Gardeners' Notes:

I hate to burst the bubble of our Californian friends but this plant is not a Californian, or even USA, native plant. It in fact comes from the South-West of Western Australia where it grows in near-desert conditions.

The trick with this plant is that when established it will send down a long tap root to find water so plant it in it's final position and don't try and move it when it is established. Trim by one third after flowering and keep it about 1.5 to 2 metres high.

If you can grow this plant you may also want to try Alyogyne Hakeifolia, also an Australian native with the same beautiful flowers but with fine, feathery leaves.

My blue hibiscus won't bloom. I've fertilized it and watered it (it's in a pot) but no flowers. Any suggestions would be appreciated.

Incredible rarity for a California native. I found one at Kings Nursery here in Santa Rosa and snatched it up ad soon as I could. As was stated, deer LOVE them and will munch down as much of it as they can. Part shade here in the toasty summer climate.

My first plant died promptly, don't really know what happened. Could have been too young a plant to survive our 2009-2010 winter, which was colder than usual. My second plant is doing great. Planted inground, part sun, has survived 2010-2011 winter. I plan to trim it in early spring to promote bushiness. Beautiful, beautiful plant. Not too easy to find in our area so grab it if you see it.

We just bought this plant and the flowers are lovely however at least half of the leaves are yellow and are falling off. Any idea why? I would love advice because I really like this plant.

I have been growing it in a foggy neighborhood of San Francisco, with sandy soil. The flowers are beautiful and it blooms off and on throughout the year. Right now, June 21st, it is covered in flowers and buds.

I occasionally add some Bay Area Forest Mulch Plus around the base and water it regularly. There was a bit of an aphid problem a couple of weeks ago, but I sprayed once with Safer Insecticidal soap and all seems ok now.

This is a very hardy and beautiful plant. We bought ours last summer and live in Houston, Texas. It doesn't really care for our extremely hot August and September afternoons, but loves the Spring and Winter. It made it through the coldest winter I remember in Houston in many years. We had two days of 25 degree weather. This plant didn't so much as lose a leaf. It is loaded with blooms now in March.

This is one hardy plant and beautiful. I planted it last spring '06 and had to move it, then move it again into a pot and finally plant it where it has been since late summer. But it has been blooming continuously since the fall and even bloomed on through a pretty hard freeze here in Southern California, completely unfazed. 10b. It rarely freezes at our house but we had a 1/2 inch of hard ice on our pond and birdbath.

I would like to plant more, the blooms remind me of a wirlywig, just beautiful

Great native plant, little water once established, prune aggressively for a dense flower laden specimen. Deer love these so plant accordingly!

I have two of these beauties planted out by the pool. I purchased them last fall and I have had almost continuous bloom, even thru the winter ! Can't wait to see how they do during our hot summer months here in CA.

I grew this shrub once...what a treasure...the exquisite blue colour of the bloom...a most unusual plant, that in some circumstances it blooms and others, very slow to put out! I am currently looking for another! good for greenhouse specimen and in the summer, outside! Elaine
