Most people picture cactus as desert plants: hot sun, sharp spines, dry sand. But that’s only half the story. There’s another branch of the family that lives in the shade of rainforests. These are the jungle cacti — epiphyte plants that climb trees, trail from branches, and throw out flowers so big and showy they look closer to orchids than to cactus blooms.

See one up close and it’s a surprise. The stems can be flat, zig-zagged, or even curly. Some trail like ferns, others pile into a shaggy basket. And when the flowers open — often at night — they’re wide, fragrant, and gone by morning. It’s no wonder gardeners like them from a first sight.

✔️ Jungle Cactus Q&A

Aren’t all cacti desert plants?

Not these. Jungle cacti are epiphytes and grow in rainforests, clinging to trees and catching rain. They never touch desert sand.

What kind of light do they need?

Outdoors, filtered sun under a tree works best. Indoors, give them bright but indirect light — east or north windows are usually safe. Direct summer sun can scorch the stems, whether inside or out.

How much water is safe?

They take more water than desert cactus but still hate wet feet. Outdoors, a rain shower is fine if the pot drains fast. Indoors, water when the top inch of soil feels dry. Always use a loose mix like Adenium mix so roots get some air.

Do they bloom indoors?

Yes. In fact, many bloom better inside where conditions are steady. They set buds when a little root-bound, and cooler nights help. Outdoors in frost-free zones, flowers come with seasonal shifts. Indoors, expect surprise buds after a cool spell by the window.

Best way to display them?

Hanging baskets show off trailing stems both inside and out. Shallow pots work well on shelves or ledges indoors. In warm climates, they can even be tied to a tree branch outside — exactly how they grow in the wild.

Extra note on indoor vs. outdoor care?

Indoors, watch for dry heated air in winter — they like a bit of humidity. A tray of pebbles and water under the pot helps. Outdoors, protect from heavy midday sun and bring them in if nights dip below the mid 30s F.

Jungle cacti are easy to keep and full of surprises. Whether trailing from a basket or blooming after dark, they prove that not every cactus belongs in the desert.

Condo Mango

Q: I was curious about indoor fruiting mango trees. I live in upstate New York and was thinking about trying to grow an indoor tree for fruit. I have a small heated greenhouse. Is there a variety that can be grown from seed that would suit my purposes and if not what is the most economical way I could obtain a cutting or small grafted plant? I keep my greenhouse around 60F in the winter and have no supplemental lighting. Are there any varieties that may work in a sunroom or other well lit indoor location?

A: There are many dwarf varieties of mango suitable for container culture. They are called "condo mangoes".
The most popular condo varieties are: Carrie, Cogshall, Cushman, Fairchild, Graham, Ice Cream, Julie , Mallika, Nam Doc Mai, Pickering. You may read more about them in our online catalog. You may also look into variety Lancetilla which is also a compact tree, and produces one of the biggest size fruit, up to 5 pounds. If you want some rare variety that hardly anyone else has - try Baptiste, an exotic Haitian dessert mango.

Your greenhouse should work for the winter time. Mango trees can take as low as mid 40s during winter and even lower as long as that cold is occasional. If you keep the temperature around 60, this should work well for over wintering. Just make sure to reduce watering to a minimum, because cool temperatures, low light and wet soil - is a bad combination for tropical plants, especially for mango trees which prefer to be kept on a dry side.

Many indoor gardeners have fruiting mango trees in their collection. However, keep in mind that the most important requirement for a mango is full sun. While you may over winter the plant for a few months in a low light conditions, in order for it to flower and produce fruit it needs lots of light. If moving the tree into full sun your yard during the summer is possible, this would be the best solution.

We always recommend SUNSHINE boosters for both over wintering tropical plants in colder climates, and for indoor gardening. SUNSHINE applications will help your tree to cope with cool temperatures and low light conditions. This will also dramatically increase flowering and fruiting performance. Another important factor for keeping your container plant healthy is quality of your potting soil. We offer a special professional mix that contains lots of good stuff: coconut fiber, peat moss, pine bark, and perlite. Fertilizing potted plants is also very important during the warm season, because this is the only way for them to get nutrients (which in the ground can be reached by spreading root system).

As far as seedlings vs. grafting - the only way to have a nicely fruiting mango tree is to plant a grafted variety. Seedlings start producing only after 8-15 years, and the quality of such fruit may be questionable. Only grafted plants can guarantee the desired taste of a variety. Besides, grafted mangoes start producing immediately - you may see fruit forming on plants as small as 3 ft, in 3 gal containers. However, during the first 1-2 years you will need to remove extra fruit and leave only 1-2 fruit so the plant doesn't get exhausted and has enough energy to establish strong root system.

Adenium: a Rose by any Other Name

New article by Jane Jordan.
"...The famous quote is often used to imply that the names of things do not affect what they really are, in the case of The Desert Rose (Adenium obesum) it is not a rose at all, rather a succulent that thrives in hot, dry and sunny conditions. These spectacular plants have no relation to the rose family, they are a species of flowering plant from the dogbane family, Apocynaceae. The naming of this plant is partly correct as they originate in sub-Saharan Africa and the Arabian Peninsula, where they can grow into large trees with huge swollen trunks..."
