The beautiful Californian Pipevine makes a showy addition to every shady spot in spring.

Curiously shaped, wooly flowers appear everywhere in the axillary buds even before leaves emerge and the plant starts growth.

Although closely related to the massive vines A. macrophylla and A.tomentosa from the US and Canada I've found it by far not that invasive and space-consuming.
