Houseplant of the Month for April 2019: the Begonia


The Story of the Begonia

Flowering begonias have full, plump flowers in cheerful colors such as red, pink, orange, white and yellow. The enthusiasm with which the plant blooms means in practice that you can hardly see the plant for the flowers. 

Foliage begonias have their own distinctive beauty in the form of velvet leaves that are beautifully marked with silver, pink, burgundy and green patterns that more than make up for the absence of flowers. 

They’re both plants with a luxurious look, yet still surprisingly simple and easy to care for. 

Begonias fit well with the trend where plants provide a soft, friendly buffer against non-stop news updates and the harsh outside world. 


There are 1895 different species of begonia, most of which grow in warm, damp forest regions in South and Central America, Africa and southern Asia. The wild species come in all sorts of shapes and sizes, but are generally herbaceous (non-woody) plants with asymmetric leaves and numerous flowers borne on branching stalks. The flowers are monoecious; that is, there are separate male and female flowers on the same plant. Most begonias have upright or creeping stems, often with distinct nodes. Many have tubers or rhizomes.

The begonia range is very extensive. 

The most common flowering houseplant begonia is the Rieger or Elatior begonia (Begonia × hiemalis) with single, semi-double or double flowers. One new addition is the Bodinia Line with extra full flowers and curly foliage. The Betulia line is also very suitable for use both indoors and out. 

There is even more diversity among foliage begonias. 

Rex begonias (B. × rex-cultorum) are available in various attractive leaf colors, structures and shapes. The Beleaf line has an attractive structure and eye-catching colors. 

Another popular group are the various rhizomatous begonias, including the eyelash begonia (B. bowerae), with creeping rhizomes and colorful leaves. They’re classics within the foliage range. 

And then there are the upright varieties with canelike stems, often called angelwing begonias, like B. maculata, many characterized by pink flowers and leaves with silvery-gray spots.

What to Look for When Buying Begonias 

  • Pot and plant must be in proportion, and the plant must look attractive and full.
  • With flowering begonias, there should be sufficient ripe buds visible. 
  • To be on the safe side, check whether it’s an indoor or outdoor begonia. 
  • Damaged leaves or leaves with marks indicate shipping damage, yellow leaves indicate a lack of water.
  • The plant must be free of pests and diseases. 

Care Tips 

Begonias need bright light, but not necessarily direct sun.
  • Begonias need a lot of light, but don’t like bright sunlight in the summer months.
  • Water as needed to keep the growing mix slightly moist at all times.
  • Try to avoid spraying your begonia; it can cause mildew (a fungus).
  • Removing wilted flowers can help stimulate new ones.
  • Fertilize lightly at each watering to keep blooming begonias in flower.

Showing Off Your Begonias

The fabulous display of begonia flowers and foliage is always appealing. 

Reinforce the soft, plump appeal of Elatior begonia flowers with soft ornamental grass and plants with velvety leaves. 

Foliage begonias can be effectively displayed in different sizes to show how versatile they are. 

For both the setting should be soft and friendly: fluffy rugs, lovely cushions, planters that seem covered in fur.

Houseplant of the Month for March 2019: The Lily


Lilies (Lilium) can make wonderful if temporary houseplants, adding beautiful color and often exquisite perfume to the décor. 

Forced lilies start to come onto the market in March and remain available until fall. Potted lilies are characterized by an upright stem bearing dense lanceolate leaves and a cluster of long buds at the top that soon open into exotic flowers. 

The choice of colors in potted lilies is extensive: from red, yellow, orange and pink through to bicolors and pastel shades.

The lily is a bulbous plant that gave its name to an entire plant family: lily family (Liliaceae). There are more than 100 known species of lily. 

It’s believed lilies first evolved in China, spreading first throughout Asia, then, via the Caucasus, the Balkans and the Alps, to Europe, and, from Siberia, to the New World. They remain largely plants of temperate climates, although a few Asiatic species are tropical. 

In the wild, lilies usually grow in a woodland setting or on grasslands with their bulb completely out of sight underground, but a few tropical species are epiphytes and grow on tree branches.

Potted Lily Range

The range of potted lilies is growing. The best-known varieties come from the Asiatic Group, often with brightly colored but scentless flowers, and from the Oriental Group, with large, highly perfumed flowers, while the Trumpet Group contributes the popular and highly scented Easter Lily (L. longiflorum). In addition, there are double-flowered lilies in pink and white, without pollen and with a light sweet fragrance. There are also compact varieties in pink or white with rounded leaves and a light fragrance. 

What to Look for When Buying Potted Lilies 

Use lilies extravagantly: you deserve them! Photo:
  • Look for a large number of swelling buds per stem. The buds should not be open at the time of purchase but can show some color.
  • The bulb must be well rooted so that the stems are firmly supported. 
  • The plant should not have any dried-out buds or yellow leaves. 
  • If there is botrytis (gray mold) present on the flower or the foliage, the plant has been kept in damp conditions or has been given too much water. Such plants should be avoided.

Care Tips 

  • While indoors, lilies like a lot of light, but not bright sunlight.
  • The cooler the plant’s position, the longer the flowers will last (up to 2 to 3 weeks).
  • Water regularly—it’s better if the soil doesn’t dry out.
  • Removed wilted flowers. 
  • After its lavish flowering, the plant won’t bloom again indoors and the bulb can be planted in the garden for flowers in future years.

Potted lilies: they’re more than a throwaway gift plant. Try them and see!

Houseplant of the Month for February 2019


Ferns are among the trendiest houseplants. Photo:


From bushy to stylized, and from dark green to silvery gray-green: ferns come in many forms with leaves (called fronds) that can also vary considerably. One has curls, another featherlike plumes, and a third has no frills at all. Together they form an attractive group of foliage plants that fit with the growing interest in botanical elements and collections in the home. As a bonus, ferns also help keep the air in the home healthy.


Young fern leaves, called fronds, are often rolled up into a fiddle-head when the form, then unravel. Photo:

Ferns are amongst the world’s oldest plants. Fossil remains have been found dating back some 420 million years, and for a long time, tree ferns were the most common plant on the planet’s surface. Seams of coal are made up of the residue of dead ferns, amongst other things. There are some 10,000 different species that grow anywhere that gets some rain. Only in deserts and locations with permanent snow are there no ferns in the landscape.

The ferns used as houseplants come from tropical and subtropical regions.

Spores, Not Seeds

Ferns propagate by means of spores. Spore casings are usually located on the underside of the frond: along veins, on leaf edges, on the end of the frond or scattered. Once the spore casings are ripe, they burst open and the spores, as light as air, drift to damp places where ferns can naturally grow.

The most popular ferns for use as houseplants are:

  • Boston fern (Nephrolepis)
  • Staghorn fern (Platycerium)
  • Bird’s nest fern (Asplenium)
  • Deersfoot fern (Davallia)
  • Blue star fern (Phlebodium)
  • Maidenhair fern (Adiantum)
  • Holly fern (Cyrtomium)
  • Brake fern and ribbon fern (Pteris)
  • Cliff brake fern (Pellaea).

Species with harder and tougher foliage are easier to look after because they lose less moisture to evaporation.

Boston ferns and staghorn ferns are best suited for use as hanging ferns.

What to Look for When Buying Ferns

  • Size, pot and height should be in proportion.
  • You’ll find the greatest variety in mixed trays of ferns.
  • The growing mix must be slightly moist. Small pot sizes in particular dry out quickly. Ferns that have been left dry for too long will quickly suffer from shed fronds, dry fronds or brown leaf edges.
  • Look for plants free of yellowing foliage. The staghorn fern’s gray-brown basal frond, though, is part of the plant.
  • Check for mealybugs and scale insects. If you discover the plant is infested, leave it in the store. They are very difficult to eradicate once you get them home.

Care Tips

  • Ferns like a bright spot, but not full sun.
  • When watering, completely moisten the potting mix, but don’t get water on the fronds. Ensure that the growing mix is always at least slightly damp.
  • Ferns do well in a spot with high humidity like the kitchen or the bathroom.
  • If the fern is placed in a room where the air is dry, place the planter on a humidity tray so water can evaporate and rise around the plant.
  • Average room temperatures are fine for most indoor ferns. Most tolerate or even prefer cooler temperatures (down to 50 °F/10 °C) in the winter.
  • Apply an all-purpose fertilizer once every 3 to 4 weeks during the growing season.
  • Cut off yellow or dying fronds.

Displaying Ferns

Ferns offer a wide choice of decorative uses indoors. Photo:

A modern way to display ferns is to place various species in a row in identical jars like in a laboratory. Also play with the various ways in which they can be used: show hanging varieties, but also ferns placed on water (evaporation creates good humility) and in a moss ball (kokedama) on a dish. Bird’s nest fern and staghorn fern can also cope with being mounted on a piece of wood.
