Gardeners' Notes:

Positive ogon On Jun 24, 2011, ogon from Paradise, CA (Zone 9a) wrote:

Huge white hibiscus flowers with red centers. Native to riparian areas around the Sacramento River in California, and can also be found in other states. Unique from many other hibiscus species in that the leaves and stems are covered in fine hairs. Since it grows in moist soil near the river, it tolerates garden conditions much better than most other California native plants, which tend to prefer dry summer conditions.

Positive FondOfFronds On Jul 31, 2007, FondOfFronds from Oceanside, CA (Zone 10b) wrote:

An amazing bloom producer both in size and quantity. The flowers start out an average size for hibiscus and then gradually get bigger. Some blooms measure 10" by the time August is in full stride. It dies off every fall only to spring back up by April. We always miss it when it dies but when it comes back we can hardly wait for it to bloom!
