Isomeris arborea, Peritoma arborea - Bladderpod
Isomeris arborea is one of those plants that you can plant and mostly leave to its own devices. I have found some nurseries now selling this plant under the new scientific name Peritoma arborea. The Bladderpod grows well without additional irrigation in all but the very driest of gardens once established. Some infrequent Summer irrigation is likely for inland gardens for the Bladderpod to look good. Warm season irrigation should be provided between heat waves, and is best with a slow deep soaking. Isomeris arborea is more likely to be killed by the good intentions of over watering gardeners than by drought. Bladderpod grows 3-4 feet tall and wide from the coastal bluffs to the desert. Isomeris arborea can be found thriving at Joshua Tree National Park. Isomeris arborea flowers from Winter into early Spring. With such distinctive fruits it only seems right that the Bladderpod often has a few seedlings nearby. The foliage is quite pungent and plants might be kept back from walkways for genteel noses. Isomeris arborea is Winter hardy into the mid teens °F if not below. Peritoma arborea is a good choice for a hot climate hummingbird garden.
