Positive Opuntia53 On Apr 3, 2007, Opuntia53 from Jamestown, CA (Zone 9a) wrote:

This CA Native Plant is a delight. It is carefree, except for minor pruning in a garden setting. It's leaves start out a lime green color and darken through summer. The flowers form a seed pod that reminds one of anise. Requires extra water during our California scorching summers and perhaps some afternoon shade. It grows along rivers and streams in it's natural state.

Calycanthus occidentalis WESTERN SPICEBUSH Dec (z8) (WNa,Fra,Cut)
This handsome medium-large shrub (4-12') with dense habit, spicily-aromatic leaves and unusual maroon-red flowers has long been a garden favorite like its sister the eastern sweetshrub. Sun-PSh/Med.moisture

Sweet Bush (Calycanthus occidentalis) grows wild along the creeks of the Sierra Nevada foothills. My neighbors and I have transplanted it into our yards as shrubs. The blooms are very aromatic and the plant is very hardy. Main means of propagation is transplanting suckers.
