Growing Pachypodium lamerei
When I first decided to plant this Pachypodium in the ground I wasn't at all sure it would live through the winter. I'd had it for a year already and was bringing it indoors on the coldest of nights during January and February. I really love it's unusual, tropical form; it looks positively Jurassic.
The Pachypodium has been happy outdoors here in our USDA 9b'ish zone. In the winter we do get a light frost every so often - seldom anything below freezing. When the nightly temperatures do flirt with a freeze many of the leaves turn yellow and fall to the ground. Once in great while ( yrs / decades apart ) we get a hard frost and when that happens I'll most likely cover it with a temporary wooden structure and cloth.
Here we are almost one year later! There has not been phenomenal growth but the plant has definitely taken on a different form. Notice how the top looks elongated and the base looks fatter which fits it's name, which roughly translates as "thick base" (or foot)
