A native tall shrub that is very adaptable; excellent for the woodland garden. The white bell-shaped flowers appear in the spring and are followed by ornamental, inflated papery seed capsules with a bladder-like aspect, which persist into early winter.
It is fast growing and tolerates a variety of soils, including clay soils. The flowers are rich in nectar and pollen attracting bees, bumblebees and other insects.
Germination: apparently, seeds have a double dormancy; they require alternating periods of cold-warm-cold stratification treatments. Alternatively, they can be sown outdoors and allow to germinate in natural conditions.
