Bilimbi, Cucumber tree, Tree Sorrel

Ethnic names are: Kamias, Belimbing Asam, Belimbing Buloh, Bimbiri. This rare exotic fruit is very popular in Thailand, Malaya and Singapore. In India, where it is usually found in gardens, the bilimbi has gone wild in the warmest regions of the country. Outside native habitat, Bilimbi is hard to find plant, very few growers produce them, although it is not so hard in cultivation.
The bilimbi is closely allied to the carambola but quite different in appearance, manner of fruiting, flavor and uses. The only strictly English names are "cucumber tree" and "tree sorrel". "Bilimbi" is the common name in India and has become widely used. Many people are more familiar with the close ralative - Averrhoa carambola - Star Fruit, which foliage looks very similar to bilimbi. The bilimbi leaves and taste of fruit are quite similar to those of the Phyllanthus acidus - Otaheite Gooseberry), although these plants are not related. Continue reading...

From Mark, the Garden Whiz. Since working in the horticultural field for nearly 50 years, at either nurseries or botanical gardens both in Florida and southern California, I have come into contact with a LOT of very cool plants.

Multi-flowering Hoyas:
from Mark, the Garden Whiz

TopTropicals.com

Q: A few months ago, i was given a Hoya vine. At the time, I was told to not cut-off the flowers but was never told why. However now that it IS flowering, they are so wonderful I would like to. Is there really a reason to not clip them off?

A: Actually, that was very good advise. Unlike most plants we encounter, hoyas develop perennial flower spikes. This means that each spike flowers more than just once! In other words, after the flowers on such a spike have gotten old and fall off, the knobby ended spike remains. Then, after a period of time, that same spike will develop another ring of flower buds. Depending on what kind of hoya it is, these perennial flower spikes may continue to periodically make more flowers for several years! And while the plant will continue to make more of these perennial spikes its whole life, the flowering display becomes better all the time as more and more spikes grow. (By the way, these are technically called "flowering spurs"). So every time a spur might be cut for ornamental purposes, it'll be one less place the vine can flower from in future years.

Season Colors from Kristi, TopTropicals Flower Queen

TopTropicals.com

Q: I live in New Jersey and I have a collection of potted tropical plants in my sun room. Our Fall season comes in bright colors, do you have something with colorful foliage for Fall?

A: For our northern customers it's almost time for the changing of the seasons. It is a very exciting and enjoyable time. The onset of fall means, less humidity, cooler nights and the Fall foliage. Here in Florida we do not get the chance to see the changing of the leaves, except maybe a few like Florida Maple Tree. So we use plants that mimic the season change, for all year round color! These are a few examples of the plants with colorful leaves that you may use for your Fall colors, plus remember - there is always a big list of Fall and Winter Flowering Tropicals!

Care for a Baobab Bonsai

TopTropicals

Q: How to grow Baobab bonsai properly? How long does it take to shape a nice little bonsai tree?

A: Baobab, or Adansonia digitata, is a unique addition to a bonsai collection. Native to Africa, it has an unusual structure and appearance. Some legends say that the tree was cast down from the heavens and landed upside down, where it began to grow. This story is no doubt a result of its appearance in the winter, when the upper branches of the tree look more like roots than treetops. The Baobab has some specific needs, but if you pay careful attention to its requirements, this tree is not difficult to grow and makes an excellent bonsai specimen.
1. Keep Baobab warm, it is sensitive to freeze.
2. Place Baobab in a bright, sunny window. Baobabs need at least six hours of full sunlight per day, so a window with a western or southern exposure is best. If your house doesn't get enough light, supplement natural light with artificial grow lights. See article Indoor lighting for tropical plants.
3. Water Baobab regularly during the growing season whenever the soil is dry. Never water the tree when it is dormant (dropped leaves).
4. Feed Baobab a good-quality fertilizer about once a month. Apply micro-element solution SUPERFOOD once a month, as well as SUNSHINE-BC plant booster for Bonsai and Caudex plants.
5. Prune the branches of your Baobab bonsai as often as they need it to give the tree the shape you desire, pruning or pinching off branches that are growing at odd angles or are too long. Trim early in the spring before new growth appears.
6. Repot the baobab bonsai every year in Spring. Remove it from pot and trim the roots back by one-third of their length, completely removing any that are damaged or dead. Place it in a container that is twice the size of the root ball and fill the pot with a well-drained soil like Adenium Mix.

It is believed that it takes forever to form a nice shaped tree, up to a few years. However if you provide warmth and bright light, branches grow very quickly, and an experienced bonsai hobbyist can make a unique specimen within 2-3 years. And then, the tree will stay with you for 5000 years - it can be passed from generation to generation!
