The great plantsman and writer E. A. Bowles called this "the most beautiful of all fern-leafed plants" and "the queen of the umbelliferae." I'm inclined to agree, and though I've never grown it myself, it's on my "must-have" list.

Big white plates of flowers to 8", branching stems often tinted red, and lacy foliage, elegantly tiered. Flowers are said to attract a variety of pollinators. Blooms July-September.

With regular water in 9b, this plant takes its time to grow and bloom, a bit over a year for me, but it grows taller than me!

It blooms for 3 months straight, the flowers are self cleaning and the foliage is so finely cut. This plants never looks messy or bedraggeld and takes no care at all besides watering.

It is evergreen where I live.

The flowers do not smell and I never see a bee on it, but they sure please me!

Mine is planted next to my fig, for a bold contrast in leaf.
