Question: Are there any houseplants that are both edible and attractive?
Answer: There are many tropical plants that are both easy to grow indoors and give us something to nibble on or to add to our recipes… but you won’t find many among the most common houseplants we grow. Most “everyday houseplants” are either not considered edible or are even poisonous. The latter group includes such popular plants as philodendrons, dieffenbachias, oleanders and most euphorbias. You don’t want to eat those!
What follows is a description of some the more interesting edible houseplants.
Plants Dropped From the List
I eliminated from the get-go certain plants that I just don’t consider to be houseplants. For example, I didn’t include most of the herbs brought indoors in the fall to grow over the winter, as in my opinion they are not really houseplants and in fact really struggle to survive indoors. You really couldn’t grow them indoors all year.
Nor did I include herbs and vegetables that are sown indoors with a view towards a quick harvest of fresh foliage: sprouts, micro-greens and baby vegetables, for example. Again, in my book, they may be indoor edibles, but they’re not really houseplants. Likewise rooted carrot tops, sprouted sweet potatoes or celery bases sitting in water. They just aren’t houseplants to me.
There are also a few poisonous plants that are edible only after they’re given some kind of special treatment, like cooking, soaking, pounding or being reduced into powder, such as taro (Calocasia esculenta) and variegated manioc (Manihot esculenta ‘Variegata’). I didn’t think it was a good idea to include potentially dangerous plants in a list of edible houseplants, as some readers might skip the “fine print”.
Everyday Houseplants That Are Edible
Here are the few common houseplants, ones readily found in almost any garden center, that just happen to be edible.
Calamondin Orange (X Citrofortunella microcarpa, syn. X C. mitis)
This is the only citrus commonly offered as a houseplant. It is inevitably already in fruit when you buy it and you just need to give it good conditions (especially, strong light) for it to continue it bloom and produce abundantly. The fruits are very bitter, but they can be used in cooking, especially in the preparation of marmalades. For suggestions of other less widely available indoor citruses, see Indoor Fruits below.
Chinese Hibiscus (Hibiscus rosa-sinensis)
The flowers are edible and often used in herbal tea. Here’s an article about this plant: The Secrets to Growing a Hibiscus Indoors.
Coffee (Coffea arabica)
Young coffee plants, usually scarcely more than seedlings, can easily be found on the market, but may be 2 or 3 years from blooming… and 5 to 6 years before producing enough beans to make a cup of coffee. Occasionally you find more mature plants already producing their highly perfumed white flowers.
You can actually eat the sweet flesh of the coffee “cherries” that follow or simply clean, roast and grind up the “beans” (seeds) to make a delicious drink.
False Shamrock (Oxalis triangularis, syn. O. regnellii)
The leaves of this popular houseplant can be purple or green, with or without a silvery or pink marking… and they are quite edible, with a sweet/sour taste. This comes from the oxalic acid they contain. However, oxalic acid becomes toxic if eaten raw in large quantities, so moderate your use. Or cook the leaves before use. Just to reassure you, remember that spinach, which we routinely eat, also contains oxalic acid and is also toxic if eaten raw in excessive quantities. As they say, the poison is in the dose: eating a few leaves will not harm you.
Ornamental Pepper (Capiscum annuum and others)
All peppers are edible, even the ones sold as ornamental plants. Be forewarned though that ornamental peppers are hot peppers, indeed, very hot peppers, generally stronger then jalapeños.
You may sometimes see them bearing the label “unfit for human consumption”, though. Why is that? It’s not because the fruit itself is poisonous, but because it was treated with an insecticide that is potentially harmful to humans. Organic gardeners will consider the fruits spoiled for life; others can wait a few weeks, then rinse the fruits before eating them. Both can harvest the seeds and grow them to produce fruits totally safe to eat in the second generation.
Pineapple (Ananas comosus)
There are several varieties of ornamental pineapple, for example with reddish foliage, variegated leaves, colored fruit, etc. And all produce fruits which, although they’re often smaller than commercially grown pineapples, are still edible.
Besides ornamental varieties of pineapple, you can also buy a fresh pineapple and root its crown. And yes, it will eventually produce an edible fruit.
Scented Geranium (Pelargonium graveolens and others)
There are a multitude of varieties of scented geranium with an incredible array of scents: lemon, rose, coconut, apple. peach, strawberry, cloves, etc. In addition to rubbing the foliage to release their scent, you can use their leaves in cooking to impart a delicious aroma to your meal. Richters (Canada) offers an especially wide choice: more than 70 varieties of these highly perfumed plants!
Swiss Cheese Plant or Monstera (Monstera deliciosa)
Often mistaken for a philodendron (which is a close relative), the monstera, with its huge, deeply-cut leaves, certainly makes an impressive houseplant. When it reaches maturity, which can take many years, it will flower indoors, producing a white inflorescence recalling a calla lily. And the flower is followed by a sweet-tasting fruit, which is the reason for the botanical epithet deliciosa. The fruit can take 11 to 12 months to mature, and doesn’t change color too visibly at maturity. So how do you know it’s ripe? When the green scales that cover it begin to drop off, it’s ready to eat.
Note that the entire plant, from its roots to its leaves to its immature fruits, is toxic. Only the mature fruit is edible.
Tea Plant (Camellia sinensis)
Yes, tea plants. although not yet as common as the other everyday houseplants presented here, are found more and more often in garden centers. Here is an article about how to grow one: Homegrown Tea in Your Teapot.
There are hundreds of different tropical fruit trees, all of which could theoretically be grown indoors, but most won’t produce for decades, will become too large to make good houseplants or require really extreme growing conditions. Since they are unlikely to ever produce fruit in your home, I excluded them from my list.
In this group of “forbidden fruits”, you’ll find most of the tropical fruits that can be grown from seeds or pits harvested from the fruits you buy, such as avocados (Persea americana), mangos (Mangifera indica), and papayas (Papaya carica). Of course, if you look hard enough, you may be able to find dwarf varieties of these plants that will produce fruits indoors, but otherwise its best to consider most tropical fruits you grow from seed simply as foliage plants!
What follows are a few fruiting plants that are more suitable for growing in our homes and that really do make good edible houseplants.
Barbados Cherry (Malpighia glabra)
Pretty pink flowers, bright red cherrylike fruits on a small shrub that fits neatly into most home decors. What’s not to like?
Cacao Tree (Theobroma cacao)
A challenge to grow and not readily found on the market, a cacao tree can still produce cacao beans at home… if you turn your home into a hot and humid jungle year round.
Citrus (Citrus spp., Microcitrus australasica and Fortunella spp.)
As mentioned in the article A Lemon or Orange Tree From Seed?, real lemon trees, orange trees, grapefruit trees, etc. are simply too large and too slow to produce to make good indoor fruit trees, unless you can find grafted dwarf varieties.
Other lesser-known citrus fruits, faster in growth and of a naturally smaller size, make much better indoor plants. This is particularly the case for the Meyer lemon (Citrus x meyeri) which, despite its name, is not a real lemon, the Key lime (C. x aurantiifolia) and the Australian finger lime (Microcitrus australasica). You can sow any one of these and have fruit 2 years later!
Kumquats (Fortunella spp.) too make excellent indoor fruit trees.
Common Fig (Ficus carica)
It prefers to pass its summer outdoors… and has the bad habit of losing most of its leaves during the winter, leading to a rather stark appearance, but the fig tree still quite readily produces figs indoors. Moreover, its foliage is edible too.
Dwarf Banana (Musa spp.)
Even a dwarf banana tree takes up a lot of space indoors (among the smallest cultivars are ‘Super Dwarf Cavendish’ and ‘Truly Tiny’) and also require a lot of heat, humidity and sun to produce fruit. Plus they may take years to produce bananas, but still, most will eventually do so if your conditions are right.
The pink banana (Musa velutina), with pink flowers and fruits, is another small-size edible banana you might like to try, but you’ll have to eat around its large seeds.
Dwarf Pomegranate (Punica granatum ‘Nana’)
This is a miniature version of the rather large pomegranate tree whose fruits are found in the supermarket. It forms a small to medium-sized shrub with orange flowers that will readily produce small but nevertheless edible fruits indoors. Even if you grow it from seed (it comes true to type), it will bear blooms and fruits in only a few years.
Natal Plum (Carissa macrocarpa)
This small thorny shrub with shiny leaves makes a good houseplant and readily produces white flowers and edible red fruits. It is sometimes used as bonsai. Both the stem and leaves, and even the sap, are poisonous. Only the ripe fruit is edible.
Passionfruit (Passiflora edulis)
This vigorous climber will need a good trellis, but can produce its white flowers with a purple halo and its purple or yellow fruits (the color depends on the cultivar chosen) in a sunny spot indoors. There are plenty of other species of passionfruit that do well indoors, but only a few produce edible fruit.
Pitahaya or Dragon Fruit (Hylocereus undatus, H. polyrhizus, H. megalanthus and others)
These climbing cacti take up a lot of space, but bloom fairly easily when they reach maturity (after 5 or 6 years), producing enormous white fragrant nocturnal flowers followed by large red or yellow fruits with white flesh that is dotted with tiny black seeds. This is a good example of a plant you can grow to fruiting size from seeds harvested from fruit purchased in the supermarket. You just have to be patient!
I grow a smaller and closely related cactus, the fishbone cactus (Epiphyllum anguliger), with hanging flattened zigzag stems whose very fragrant nocturnal white flowers often give small edible green fruits… but it’s difficult to judge when they are ripe. It too takes years to begin to bloom, but once it starts, it will faithfully continue to do so.
Pixie Grape (Vitis x Pixie® Pinot Meunier)
A dwarf mutation of the Pinot Meunier grape vine which produces fruit all year on a small plant… and its leaves are edible too. It can be grown as a houseplant, but is also hardy outdoors.
Roselle (Hibiscus sabadariffa)
This shrub with small yellow hibiscus flowers grows quickly from seed. In fact, you can treat is an annual if you wish. It produces red fruits often used in drinks and jellies.
Indoor Herbs and Spices
Herbs and spices flavor our meals and often have medicinal uses as well. I limited the choice here to varieties that really make decent houseplants.
Bayleaf (Laurus nobilis)
In my opinion, this is the only “classic” herb that grows well enough indoors to make a good houseplant. It will grow indoors for years, eventually forming a tall shrub if you don’t prune it. The leaves can simply be plucked and used fresh as needed.
Black Pepper (Piper nigrum)
This climbing plant produces smooth shiny leaves and long spikes of green berries that turn red at maturity and is not difficult to grow indoors if you can offer good humidity. The berries give black, white or red pepper, depending on the treatment you give them.
Ginger (Zingiber officinale)
You can readily grow ginger from rhizomes purchased locally. Beware though that the rhizomes offered in many supermarkets were treated chemically or irradiated in order prevent them from sprouting. There is no use planting those! You need live rhizomes, with buds indicating they are ready to sprout. An Asian supermarket should have some.
Just push a section of rhizome into a pot of growing mix and water: a green rather bamboolike plant will soon start to sprout. Over time, the rhizome will spread and you can then harvest and eat any surplus. Don’t expect this plant to flower indoors, though: it almost never does.
Other spices in the ginger family also produce edible rhizomes and likewise make excellent houseplants: galanga (Alpinia galanga), turmeric (Cucurma longa) and cardamom (Elettaria cardamomum) are only a few examples.
Society Garlic (Tulbaghia violacea)
This is a bulbous plant with grasslike leaves and small pink trumpet flowers. The whole plant smells like garlic. If you use the edible leaves and flowers in your cooking, they’ll give the meal a garlicky scent, but without the bad breath that follows eating real garlic. The name society garlic come from the idea that you could safely eat it before attending polite society functions.
Spanish Thyme or Cuban oregano (Plectranthus amboinicus)
This plant is neither a thyme (Thymus spp.) nor an oregano (Origanum spp.), but rather a tropical plant closely related to the coleus (Coleus scutellaroides, syn. Plectranthus scutellarioides). It’s a very popular herb in tropical countries where its thick leaves lend taste of oregano to cooked dishes. It’s very easy to grow.
Stevia or Sweetleaf (Stevia rebaudiana)
Increasingly popular for its sweet leaves that give dishes a sugary flavor without adding calories… and it makes a decent houseplant.
There aren’t many plants you could call vegetables that also make good houseplants. I could only think of the following two:
Malabar Spinach (Basella alba)
An ornamental climber with mucilaginous leaves used to replace spinach, Malabar spinach is often grown in hot climates where real spinach doesn’t grow well. The species itself produces green stems and white flowers, but B. alba ‘Rubra’, perhaps even more commonly grown, has reddish stems and pink flowers. Both are very easy to grow.
Nopal or Barbary Fig (Opuntia ficus-indica and others)
Many different opuntias are used as nopals, but Barbary fig is the most common one. This cactus with flattened pads does produce edible fruits called Barbary figs when grown outdoors in a hot, dry climate, but indoors it rarely blooms, let alone produces fruit. It made it onto my “edible houseplant list” by virtue of its edible pads.
Nopal is the name commonly used in Mexico for the pads treated as a vegetable. You’ll probably need several plants if you want to start harvest nopals, as the plant is very slow growing. You have to singe off the spines before you eat the pads… or use spineless (or nearly spineless) cultivars like ‘Burbank Spineless’.
This plant will need full sun to do well indoors. And yes, you can root a pad from the grocery store to start a new plant.
Where to Find Edible Houseplants?
Many of the plants above are not found in just any garden center, so here are few places where you might want to look for them on the Web.
For herbs and species, try Richters, a Canadian company that ships to the US and probably offers more choices of herbs than any other.
For unusual fruits and vegetables, try Flora Exotica, also a Canadian company that ships to the US, while Top Tropicals is an American company that ships to Canada and many other countries worldwide. Logee’s, in the US, is a good source for American readers, but no longer ships to Canada.
For European readers, try AlsaPlants. If you know of any other good mail-order sources of indoor edibles in Europe, let me know and I’ll add them to this text.
I just wanted to let you know that I used the information in your very informative article for my own blog post “Zelf eten verbouwen zonder tuin” (Growing your own food without a garden), to be found at:
Naturally, I added a link to this article in my source list.
Thank you! I love to share! ?
Wonderful post, thank you! I am working on compiling a large list of edible houseplants, and hoped I could ask you a bit about your experiences with the fishbone cactus. What are the light conditions where you grow it? And does it receive any supplementary lighting, or time outdoors in summer? Many edibles only produce fruits indoors in unsually high-light conditions, so I am interested in how this is growing with you. Many thanks!
I’ve grown this plant for decades. It does spend the summer outdoors in shady spots (under tree branches) and sometimes does bloom there, but mostly indoors during the winter, months later. I’ve seen it in bloom in homes where it never goes outside.
Indoors it has been under various conditions, but mostly high light. Nothing exceptional, though, and where I live (above the 46th parallel with a cloudy climate), it would not be getting much sun in winter.
As for fruiting, I was surprised the first time mine did, as I had been told epiphyllums needed cross pollination, but apparently some self-pollination occurs. And fruits that formed after a winter bloom had no insect pollinators.
Very interesting. I had also read that it needed pollination, and having to make sure to get two genetically differentiable individuals was putting me off growing this plant. But I still wonder whether it would be able to fruit indoors without the boost of spending the summer outdoors. Do you know someone who grows them indoors year round (without grow lights) who have gotten fruits?
Very interesting. I also read that it needed a pollinator. The need to get two genetically distinct plants was what was putting me off growing this plant. I wonder whether it would be able to fruit without the boost of being outdoors in summer? Do you know someone who grows theirs indoors year round (without grow lights) and have gotten fruit on theirs?
I’m really envy looking at this beautiful Anguliger. It’s no where to be found in Asian countries, even if I find one, its of different variation. I only want this variation of Anguliger.
I tried purchased online, seller sold me Selenicereus Anthonyanus instead of this one with the white bloom. I’m so disappointed. Both absolutely different in stem loop and different lightning needs. I do not like the red bloom.
I can do absolutely nothing but just only to look at the beauty of this on the internet. Really hate how these 2 specimens mixed up.
Since this plant is becoming popular in Europe and North America, perhaps it will start to show up in Asia soon as well.
I have a Madeira vine (Anredera cordifolia) that lives in my kitchen windowsill and works mainly as a spinach, but also produced edible tubers occasionally : https://theunconventionalgardener.com/blog/munching-madeira-vine/
Very interesting! I’ve been growing this plant for years, but have yet to get around to tasting it!
