Have been growing several trees from rooted cutting [bought online] here in zone 7a for almost 4 years now. All kept in pots and overwintered in heated room. Largest is roughly 7ft and is in a 5gal hydropower which I keep in a 17gal plastic tote. The tote I keep filled with several inches of water year round. It is cumbersome to move seasonally but I manage with a dolly and imo is worth it. Thrive in moisture and high humidity. Love heat aswell , humid heat, but do have slowing of growth at temps above roughly 100F and the same slowing/halting of growth below 55F/60F [estimate] they also tend to like acidic soil from what I can tell. Usually mix organic compost, vermiculite, peat moss, and top soil for my Mitragyna. Blooms are yellow and very reminiscent of the Temperate climate Button Bus... read more

Was wondering if anyone would be able to donate and mail any houseplant succulent and airplants to an ill relative as their last wish. Needs to be potted please.

The leaves of this plant have many beneficial medicinal qualities. The species is one of the most useful, yet overlooked, of the ethnobotanicals/homeopathics in western medicine.

I bought 2 rooted cuttings to add the plant to my medicinal plant collection. They love the long, hot humid summers here, but have to be taken inside when temps dip below 50F or the huge leaves will start to fall off. The trees rapidly grow too big to be moved! Fortunately, they grow well from green cuttings, potted in sterile medium inside ziplocs under lights with or without rooting hormone, so you can start fresh every year.

Do not let the soil dry out on hot sunny days or they will wilt and scorch! They are heavy drinkers and feeders. Outdoors, few pests. Indoors, spider mites are a major problem, whiteflies and aphids less so.

From a distance, they look like avocado trees, but on close inspection, you notice the unique spearhead-shaped bud sheaths, which ... read more

I ordered this tree from as a rooted & potted cutting in early May of 2011. It was in fabulous condition when it arrived after three days in the mail.

I was told that it would need to adjust to my area (9b) but that where it grows naturally in Thailand has a very similar to climate to that of Florida. The tree took off within a month, and has branched out beautifully; I initially had a small issue with aphids, but I dusted it, and haven't seen any bugs since.

What I've learned so far about this tree:
It prefers partial sunlight as a young tree; direct full sun will burn it.
One can scarcely over-water it. Remember it's indigenous to a rain-forest.
One should bring the tree inside if temperatures fall below 45F. (This is w... read more

I think I may have waited too long on the planting, I guess seeds are not viable for any length of time. Will put in my own pictures if they do!

Leaves can be used as a stimulant and pain killer but there are some side effects. This plant is indigenous to Thailand where it is actually illegal. It's a gorgeous tree, though. Great addition to a tropical garden or ethnobotanical collection.
