Pachypodium bispinosum is native to South Africa and is a small shrub reaching between 2 to 5 feet in height. To get the bushier shape and abundance of flowers, prune it regularly. The plant is an eye-catching one with its strong, spiny and succulent limbs, spines, and waxy, thick leaves. It enjoys full sun position in the garden, however, it also tolerates semi-shade. Pachypodium should be watered moderately and tolerate dry conditions quite well when established.
The most attractive feature of the plant is the sweetly scented, white or off-white flowers, with a blush of pink at the center. In a sunny blue sky day, the bright magenta of the red and crimson, vinous colors are irresistible.
It is a deciduous plant and the leaves will drop off in cold winter temperatures, showing the impressive caudex that occurs where the trunk is covered with soft and grainy thorns or spines.
These plants are grown mainly in USDA Zone 9-11, with some reports of success in Zone 8. It can also be grown in pots, in colder regions. In Southern Europe, the plants are sometimes grown as houseplants, such as in Germany and the UK, where it is sometimes ok to keep the pot outside during warmer months, provided the temperature does not drop below 40F. During the cold winter months, water the plant sparingly and, if the temperature drops too low, bring the plant in to a bright and airy room and keep it totally dry.
These plants are relatively hardy and low-maintenance, and a great option if you looking for an exotic perennial to add to your garden. With some care and attention, you can ensure that you get a beautiful, unique and eye-catching specimen worthy of any garden.
