Gardeners' Notes:

I bought this plant about a year ago, and it has never bloomed. It has grown a lot, and we like the look of it as a shrub in one of our sunny beds, but I don't know why it won't give us those beautiful pink flowers. Is it an age thing? I think I bought it in a one-gallon container, but other than that, I have no idea how old it is. It's about five feet high, and even more wide, and we do trim it back from time to time, mainly to back it off our driveway. Any insight on how to get it to bloom would be appreciated.

Neutral Floridian On Nov 12, 2001, Floridian from Lutz, FL (Zone 9b) wrote:

This oriental looking shrub has a tendency to grow more horizontally than vertically. It has cascading branches and powder puff white/pink flowers. The flowers are mimosa-like "powderpuffs". Each flower opens for a single night to display showy filaments, which usually are white at the very base and red at the tip (although they may be pink). By the next day, the filaments have wilted, and unfertilized flowers drop.
