The most popular Christmas plant in North America is certainly the poinsettia (Euphorbia pulcherrima). There is scarcely a store that doesn’t sell them or a home that isn’t decorated with one. But there are other Christmas plants, including Christmas cactus (Schlumbergera spp.), Christmas kalanchoe (Kalanchoe blossfeldiana), amaryllis (Hippeastrum spp.), Christmas pepper (Capsicum annuum), Jerusalem cherry (Solanum pseudocapsicum), frosted fern (Selaginella martensii ‘Frosty’), Norfolk island pine (Araucaria heterophylla) and, more recently, wintergreen (Gaultheria procumbens).

Christmas trees are popular all over North America, too. Fir trees (Abies spp.) are the biggest sellers, but Douglas firs (Pseudotsuga menziesii), spruces (Picea spp.) and pines (Pinus spp.) are widely used.

The Christmas fern (Polystichum acrostichoides) was once commonly used in Christmas wreathes, garlands and centerpieces in Eastern North America, as it has evergreen fronds that last all winter and are thus available at Christmastime, but its star has waned considerably. It’s just too easy to find longer-lasting artificial or preserved foliage for such use these days. The Christmas fern still makes a great garden plant for shady spots and is hardy to zone 3.

The branches of winterberry (Ilex verticillata) have fared better over time and are still widely used. This deciduous holly, native to eastern North America, is leafless at Christmas, but its branches are covered with bright red berries that create great swaths of color in Christmas arrangements. You can grow them yourself (the shrub is hardy to zone 3 and you will need to include at least one male plant in your planting to pollinate the berry-bearing females), but you can also buy branches in florist shops … including fake ones, unfortunately.

That covers most of the plants associated with Christmas in North America, but Christmas plants differ around the world. Let’s take a look at what’s going on elsewhere.

Europe

In general, the plants featured in the first paragraph—poinsettias, Christmas cactus, Christmas kalanchoe, etc.—are also popular in Europe, although the poinsettia, even though it is not rare per se, is not as popular as on this side of the Atlantic. But there are other plants associated with Christmas (and New Year’s Day) that are more specific to Europe.

For example, holly (Ilex aquifolium) is a European shrub or tree with spiny-edged, shiny, leathery, evergreen leaves and red berries and is grown in many Old World gardens. True enough, holly is available on a limited basis in North America too (although are mostly seem either on Christmas cards or as sprigs of plastic leaves), but nothing to the extent to which it is used in Europe, where, in some countries, sprigs of holly are found on nearly every window ledge and doorway. This tradition has come to be seen as a sign of welcome, but is in fact based a centuries-old belief that putting holly on all possible entranceways would prevent evil spirits from invading the home.

Kissing under the mistletoe during the Christmas season is a very old European tradition and can be traced back to the time of the Druids, who laid down arms and exchanged greetings under the mistletoe, considered to be a very sacred plant. Mistletoe is a parasitic plant that grows on tree branches, counting on sap it absorbs from its host for its survival. European mistletoe (Viscum album)—with its translucent round white berries—is the original variety to kiss under.

The tradition of kissing under the mistletoe was brought over to the New World and thrived for awhile, but now appears to be dying out. Certainly mistletoe is now only available very locally in North America: I haven’t seen a sprig of it in years! It’s still widely used in Europe during the holiday season.

English ivy (Hedera helix) is a traditional Christmas plant in Europe, widely used in holiday garlands and wreaths. Think of the carol The Holly and the Ivy, for example. And why not, since this evergreen climber grows abundantly everywhere on that continent and so is readily available! The tradition of using ivy as a Christmas decoration never caught on in North America, probably because ivy is neither native nor widely grown, though it has escaped from culture to become abundant in a few areas. Harvesting ivy for Christmas decorations is something that could be encouraged as a control measure in areas (mostly on the US West Coast) where ivy is proving to be a pernicious weed.

The Christmas rose (Helleborus niger) is not a rose (Rosa spp.) at all, of course, but a perennial. It’s a traditional Christmas plant in southeastern Europe, notably in areas where Orthodox Church is the common religion. Orthodox Christmas takes place about two weeks later than in Western rites, around January 7. And this very early perennial is usually in bloom by then. Although mainly used in flower beds or naturalized in woodlands, it’s also sold as a gift plant at that season.

Elsewhere in Europe and pretty much everywhere in North America, this plant flowers too late to be a Christmas plant. Where I live, it isn’t even in bloom at Easter … it’s more like a Mother’s Day plant!

In Europe, the tradition of Christmas trees is well established and often spruce or pine, or even a juniper or other conifer, are used, depending on what is available locally.

The tradition of the Yule log has largely died out in Britain and Central Europe as it has in North America, but in many parts of Europe, notably in Scandanavia and Eastern Europe, it remains deeply entrenched. A Yule log is a very large hardwood log, the idea being to light it on Christmas Eve and have it burn through the night and Christmas Day. In the Balkans, the Yule log is called a badnjak (or budnik, according to the local language) and it is usually an oak, a symbol of longevity. Those who do not have a fireplace to burn a log in often decorate their apartment with twigs of oak.

In France, Belgium and Switzerland, the Yule log (bûche de Noël) has morphed into a log-shaped cake, traditionally served at Christmas … you don’t need a fireplace for that!

The main Christmas plant in this region is the pomegranate (Punica granatum): a perfect choice, as it matures at just the right time of year. Doors, fireplaces, tables, etc. are decorated with pomegranate fruits, both fresh and artificial.

Two other plants often used in Christmas decorations are the shrubs butcher’s broom (Ruscus aculeatus) and firethorn (Pyracantha spp.), both bearing evergreen foliage and red berries.

In Israel, olive branches (Olea europaea) are offered at Christmas to friends as a symbol of peace.

Mexico

The poinsettia (Euphorbia pulcherrima) is native to Mexico and is popular in there, where it’s known as flor de Nochebuena (Christmas Eve flower). Butcher’s broom and firethorn, brought over from Spain, are also popular, as well as are several local plants that bloom at Christmas.

Manzanita, also called tejocote or manzanilla (Crataegus mexicana), a large-berried hawthorn, is another plant traditionally used as a Christmas decoration in many parts of Mexico and Central America. The orange fruits may be threaded onto a garland and are also used to make Christmas punch.

One of Mexico’s most curious Christmas traditions, however, is the Night of the Radishes (Noche de Los Rábanos), celebrated in the region of Oaxaca on December 23rd. In it, radishes are carved and arranged into some very impressive displays.

South America

Since most of this continent lies south of the equator, the seasons are inverted and Christmas takes place in summer, not winter. That means traditional Christmas plants of the Northern Hemisphere bloom six months too late for Christmas. As a result, the poinsettia is called “Easter flower” (flor de pascua) in many South American countries, because it blooms at Easter, while our Christmas cactus (Schlumbergera) is called “flor de maio” (May flower) in its country of origin, Brazil. Yet there is a Christmas cactus in these countries. The plant we call Easter cactus (Hatiora gaertneri, formerly Rhipsalidopsis gaertneri) in the North is the “cactus de Navidad” and blooms at Christmas in much of South America.

South Americans tend to use native plants as cut flowers or holiday plants at the Christmas season. Branches of the Brazilian peppertree (Schinus terebinthifolius) and its cousin, Peruvian peppertree (S. mollis), known in the north for the pink peppercorns they produce, are often used to decorate churches and houses during the holiday season, as they are loaded with small red berries at that time of year.

Venezuela has its own Christmas orchid that blooms for the holidays: Cattleya perciviliana. Elsewhere in South America, the usual “orquídea de navidad” is Angraecum sesquipedale, actually native to Madagascar, but widely grown for its large white star-shaped flowers. It’s also called estrella of Belén (star of Bethlehem), but then, so are many other white, star-shaped flowers, including bulbs of the genus Ornithogalum.

In Paraguay, house and Christmas displays are often decorated with “flores de coco,” the long, fragrant inflorescences of a local palm tree, the coyol (Acrocomia aculeata). This pre-Christian tradition comes from the indigenous Guarani people.

Asia

In general, the concept of Christmas is relatively new to this continent and the celebration is mostly a commercial one of American inspiration, so there are often no traditional plants associated with the holiday, at least not long-standing ones. Most are the same Christmas plants seen in North America (poinsettias, Christmas cacti, etc.). Christmas trees, almost nonexistent only 30 years ago, for example, are now seen everywhere, although more often in shopping centers than in private homes. Usually artificial trees are used.

The Christian population in Japan is more firmly established than most in Asia and has solidly adopted the tradition of the Christmas tree, usually a real fir or spruce tree. Heavenly bamboo, Nandina domestica, which is not a bamboo at all, but a shrub, is the second-best-known Christmas plant, with its scarlet fruits and red winter leaves. Chrysanthemums (Chrysanthemum morifolium), popular in all seasons in Japan, are widely used at Christmas too.

In China, an apple wrapped in colored paper or stamped with an appropriate seasonal message is often offered as a gift on Christmas Eve because the word “Christmas Eve,” translated as “night of peace” (Ping’an Ye) in Mandarin, sounds like the word apple (píngguǒ).

In the tropical regions of Asia, the Christmas palm (Adonidia merrillii), better known by its old name, Veitchia merrillii, is widely grown. With its stocky trunk and relatively short fronds, it looks like a dwarf royal palm … and bears bright red fruit at Christmas. Originally from the Philippines and Malaysia, this palm is now grown throughout the tropics.

Finally, in India, the golden Monterey cypress (Cupressus macrocarpa ‘Goldcrest’) is growing in popularity as a Christmas tree, but otherwise, Christmas is little celebrated in India.

Africa

The traditions of using Christmas plants are more firmly established in South Africa than in the center and north of the continent, brought to this region by European settlers (notably the Dutch and English).

Again, though, with the seasons being inverted, the South African Christmas plants are very different from those in the Northern Hemisphere. Notably, the hortensia (Hydrangea macrophylla), well-known in the North for its summer bloom, is called “Christmas flower” and is by far the most popular Christmas plant!

On the other hand, poinsettias are catching on as well. They have to be specially prepared in order to bloom at Christmas rather than in May, which is when they’d bloom if left on their own. Local nurserymen manage to do this by covering their production greenhouses with black cloth after 4 pm to ensure the short days necessary to stimulate bloom.

Various native plants also serve as Christmas plants, such as Christmas bush (Pavetta spp.), Christmas bells (Sandersonia aurantiaca) and Christmas berry (Chironia baccifera). Several plants imported from Australia, which has a similar climate, are also appreciated for their winter bloom. You’ll read more about those below. Africans also celebrate Christmas with many plants that are for us just typical summer flowers, like daisies, roses and zinnias.

Christmas trees are very popular in South Africa, but they use as subjects conifers adapted to local conditions, such as cypress (Cupressus spp., including C. macrocarpa), Japanese cedar (Cryptomeria japonica) and various pines (Pinus spp., including P. radiata).

Australia

In Australia, the traditional Christmas tree is the native Norfolk Island pine (Araucaria heterophylla). Grown in mostly as a houseplant in the northern hemisphere, where it rarely exceeds 5 feet (1.5 m) in height, in Australia, it can eventually reach up to 250 feet (65 m) in height, about 20 floors! Other mild-climate conifers from various parts of the world are also used as Christmas trees, including various pines.

And Australians have their own Ozzie Christmas tree, Nuytsia floribunda … but it’s not a conifer, but rather a broad-leaved tree. Moreover, it’s a parasitic tree (or rather hemiparasitic tree, since it does carry out its own photosynthesis) that steals most of its water and minerals from nearby plants! The Australian Christmas tree produces frothy spikes of orange-yellow flowers just in time for the holidays.

To add to this, each Australian state seems to have its own “Christmas bush,” always a shrub that produces masses of either flowers or colorful fruits at the right season, including Correa spp., Chromolaena odorata, Ceratopetalum gummiferum and Prosanthera laisanthos. Also, there are many bulbs that bloom at Christmas, including various species of Blandfordia, called “Christmas bells.” And Australia also has its own Christmas orchid: Calanthe triplicata, native to the north of the country

New Zealand

Mention Christmas tree to any New Zealander and they’ll immediately think of Meterosideros excelsa, a rounded broadleaf tree with feathery red flowers at Christmas. It’s called the New Zealand Christmas tree or pōhutukawa. And an introduced bulb from South America (Alstroemeria psittacina), with green-tipped red tubular flowers, has “gone native” and is well-known by locals as New Zealand Christmas bells.


So, wherever you travel around the world, there are always interesting Christmas plants to discover!

Frosted Fern: A Christmas Mystery Plant

Standard
20161214a

Selaginella ‘Frosty’ is often sold with various Christmas decorations to stimulate sales.

Among the plants sold during the Holiday season, the so-called “frosted fern” is certainly the most mysterious, because not only is there is so little information about it, but most merchants don’t even seem to know what to call it!

You see, this plant is not a fern at all, but what is known as a spikemoss (Selaginella), a primitive plant not really that closely related to true mosses (bryophytes) either, but rather to clubmosses (Lycopodium and others). So you could call it a “fern ally”, but still, it’s neither a fern nor a moss.

The plant in question is Selaginella martensii ‘Frosty’, but it is generally sold, when indeed any semblance of a botanical name is used at all, as S. kraussiana ‘Frosty Fern’. The real S. kraussiana, though, is a low-growing and distinctly creeping plant, rarely more than 2 inches (5 cm) tall, that forms a spreading carpet, whereas ‘Frosty’ is very different and clearly a variant of Marten’s spikemoss (S. martensii) with its more upright habit and tufted growth.

Description

20161214b-pick-ontario

The arching stems of scalelike leaves make the plant look rather like an arborvitae (Thuja).

Selaginella ‘Frosty’ can grow to be up to 1 foot (30 cm) tall, but only under very good conditions. 6 to 8 inches (15 to 20 cm) is more likely in most homes. It forms a dense clump of stems that are upright at the base, then arch outwards. They then branch repeatedly, forming a flattened fan, and what with their covering of tiny scalelike leaves, make the plant look very much like an itsy bitsy flat-topped arborvitae (Thuja). Curiously, ‘Frosty’ occasionally produces long stiltlike aerial roots that descend from the stems towards the soil.

The name Frosty comes from the coloring of the new growth at each stem tip. It is white at first, contrasting with the darker green color of older sections, and this does gives a frosted look to the plant.

20161214d

This isn’t ‘Frosty’, but another cultivar of S. martensii: ‘Variegata’. It’s white coloration is not strictly limited to the leaf tips.

S. martensii ‘Frosty’ differs from another variegated selection of Marten’s spikemoss, S. martensii ‘Variegata’ (‘Albomarginata’), in that its variegation is limited to the tips of the stems. In ‘Variegata’ the white coloring is more sporadic (only a few stems are affected), but since they doesn’t green up over time, the stems that inherit the discoloration keep it, creating patches of white. As for S. martensii ‘Jori’, another cultivar sometimes seen, it’ very similar to ‘Frosty’, but the stem tips are yellow rather than white.

Neither of these are as commonly seen as ‘Frosty’.

Greenhouse Conditions are a Must

20161214c

Note ‘Frosty’s aerial roots, produced only under the highest humidity.

Although you’re likely to see selaginella ‘Frosty’ sold in nurseries as a holiday plant, it actually doesn’t do at all well in the average home. If it holds up in the greenhouse section of plant nurseries, it’s because of the high humidity that prevails there, but when you bring it home, the plant tends to die rather quickly… unless you know what to do.

You see, it needs very high humidity, of the order of 70%, otherwise it dies back little by little, starting at the tips. That’s far more humidity than just about any household can provide, at least during the winter heating season.

So when you bring this plant home, don’t just set it on a windowsill and think your job done. You’ll need to grow in on a humidity tray or inside a terrarium, either open or closed. Or seal it inside a clear plastic bag for the winter. It will also perform well in a very humid greenhouse. And before you even ask, no, misting it on a daily basis will not help at all, while running a room humidifier will only help a bit, as most humidifiers don’t produce enough humidity to meet the needs of this plant that is dreaming of its homeland, the steamy jungles of Mexico.

Once the Humidity Problem is Fixed…

Once you meet its requirements for high atmospheric humidity, ‘Frosty’ selaginella is much more accommodating.

When it comes to light, for example, it is satisfied with medium or even low lighting. No direct sun is necessary or even desirable, although northern gardeners shouldn’t be afraid of exposing it to direct sunlight during winter, when the sun is very weak.

The soil must remain moist at all times, so water as soon as the soil appears to be dry to the touch. It may be necessary to water this plant more than once a week if it’s exposed to the air. Plants in a terrarium, though, won’t need as much attention, as they lose less water to evaporation. In a closed terrarium or a sealed plastic bag, your plant may not need more than a spoonful of water two or three times a year!

20161214e

The white tips tend to be only visible in winter.

Don’t worry if your plant loses its frosted coloration in the summer. It does so because daytime temperatures are too hot (the white cells turn green at temperatures greater than 70˚F/21˚C). Its frosting will return when temperatures drop in the fall.

Be careful when you fertilize this plant: products too rich in nitrogen (the 1st number) can also make the white parts turn green. The easiest solution is to rarely fertilize it and, when you do, only with a very diluted fertilizer. One or two annual applications of a very dilute soluble fertilizer (1/8th of the recommended rate) is plenty.

Other selaginellas have turned out to be invasive when planted outdoors. I don’t think this one would be, but still, if you plant it outside in a humid tropical climate where it might escape, like Southern Florida (hardiness zone 10 or above), keep a watch on it. It won’t be invasive in temperate climates, as its frost resistance is nil.

Finally, our little selaginella seldom suffers from insect or disease problems. And there’s no need to be concerned about the health of your kids, your pooch or your kitty: selaginella ‘Frosty” simply isn’t poisonous.

Propagation

Multipiying selaginella ‘Frosty’ by stem cuttings is a snap: simply pluck a section of stem and press it into a pot of moist soil, then maintain high humidity by covering the container with a transparent dome or plastic bag. It’ll root within a week or so.


So there you go: a more complete picture of a widely available Christmas plant that has pretty much gone under the radar until now. Best of luck with it!20161214c
