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 Bladder
Pod 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 margins of the desert. 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.
