Just a quick comment for those curious about it's hardiness- about 2 years ago I planted a 2-foot high specimen in a relatively sheltered position, receiving a little shade in summer and around half-day shade in winter. It is a free-draining, somewhat dry site with fairly crappy soil.
It's now about 6 feet tall and beginning to power away, putting on canopy and looks set to really get going next summer. It gets no extra water or feeding, in fact, no attention at all! To me it seems to grow slowly throughout the year, with the most growth coming late summer/autumn.

For climate context, we are sea-side, with good humidity. We get the occasional mild frost but the ground never freezes, brief snow, some hail, wet wint... read more

writterkat-there is NEVER a good time to top a tree!!! you basically want to cut it in half- its not a perennial- have it PROFFESIONALLY pruned and every few years

After germinating and growing this plant for a year i've found that it is not exclusively a cool grower, so it can be cultivated even in areas with warmer summers than of coastal California where it thrives. Scarification of the seeds is necessary to achieve high germination rates. I've posted a photo in the gallery of the plant here with photographic details.

Hi everyone, Im new to this site but I hope you can help me with some information on the Chiranthodendron pentadactylon tree! I bought this tree when it was only a foot tall because I loved the pictures of the blooms; it has now grown to twenty feet high in one and a half years. I would like to top it off so it grows no higher than ten to twelve feet. Is there a best time and way to do this so I don't hurt it? I will say I think this tree seems to be indestructible and I am amazed at how fast it has grown. I also would like to know when they usual bloom for the first time.
Thank you.

I LIVE IN PLIMMERTON, PORIRUA, NEW ZEALAND AND ABOUT FIVE YEARS AGO THE MONKEYHAND TREE I HAD BLEW DOWN IN A STORM. I COLLECTED ALL THE SEED PODS AND ABOUT TWO YEARS AGE I DECIDED TO HAVE A GO AT PROPIGATING THEM. I PUT ABOUT THIRTY SEEDS STRIGHT OUT OF THE PODS IN A TRAY OF SEED RAISING MIX AND LEFT THEM OUTSIDE AFTER ABOUT THREE MONTHS ABOUT 25% OF THEM SPROUTED THEY ARE BETWEEN FOUR AND NINE FEET TALL NOW AND DOING WELL. TO OPEN THE PODS I PUT THEM IN A VICE AND FORCED THEM OPEN WITH A SCREWDRIVER WE GET VERY LITTLE FROST HERE AND THE TREES ARE ON THE HILLSIDE FACING THE SEA

My son just brought this Monkey Hand tree flower home from SF Botanical garden and I'd like to know what is the best way to plant it if possible at all (please see uploaded picture above).

Thanks,

I am so glad you posted the above regarding the propagation from seed as I have some of these seeds and have been trying to find information regarding that subject. I just got the seeds this past weekend. They are black. I will try your instructions on the refrigeration then boiling water etc. The seeds are relatively small and scoring them or sanding them seems like it might be a difficult task. But I will see what I can do. Having to cool them in the fridge for 3 months seems like something I might not have the patience for but I will try it out. I am real anxious to grow this tree.
7/22/06-Since the above posting by me, I have been able to germinate one so far and have posted a picture of it. It is still just a little baby in a teeny tiny pot. I have also purchase a 15 g... read more

My location is Auckland, New Zealand.
There has been a Mexican Handflower Tree growing on my property for about 15 years.
The tree is growing in clay - there is very little top soil here where the climate is subtropical. We seldom if ever get frosts and the summer temperature does not normally exceed mid to low thirties centigrade (mid eighties farenheit).
The tree is growing in the foothills of the Waitakere Ranges where the annual rainfall is 2000mm (80 inches).

The tree produced seed pods for the first time this year in summer. It is now the end of May and we are approaching mid-winter. The pods are still in place on the tree although we have removed a few upon which to experiment. Most of the summer's pods have not burst open although we did f... read more

I have a Monkey Hand Tree in my backyard that is about 60 years old and stands 40+ feet tall. I am in the Mar Vista area of Los Angeles, CA. The tree is healthy even though it has had some heavy pruning where it extends over my neighbors properties. Although it drops seed pods every spring, it has never propagated in the 37 years that I've owned it. The flowers are extremely striking and look more like a "devil's hand" than a "monkey's hand". It does seem to be producing less flowers than it did when it was younger. The flowers have a double row of yellow pollen on the back of each finger of the scarlet hand. Perhaps it needs cross pollenization from similar trees in order to propagate. The tree was imported by the Paul Howard Nursery in the late 40's and there is, or was, another ... read more

Chiranthodendron is Greek for "Tree with a hand-shaped flower." Pentadactylon is Greek for "5-fingered." Rare tree, even in it's native Mexico and Guatemala. It is reported to tolerate light frost. It should be grown in full sun, in a well drained location.
