Gardeners' Notes:

I'm confused about the identification of this plant. In Sunset Western Garden Book and elsewhere on the Internet, Microphyllus seems to refer to the compact shrub that grows only 2 to 3 foot tall. I believe that is what i have. It's about two years old and is only 18 inches tall. I think that it is the Microphyllus Variegatus. It is doing well in full sun and growing in compacted clay soil. I only wish that it would grow 6 feet tall or more.

We had this plant growing in Ventura, California...and when we moved we bought one to put in front of our house near the driveway (it also hides a telephone pole stabilizing wire). It has grown quite a bit in 20 years...I'm sure it's at least 8 feet tall. We have a range of weather patterns from drought to below freezing to 110 degrees in the summer...and this plant can take it all. It has never appeared to be fazed by any kind of weather, but puts out those bright yellow leaves with constant energy and is quite lush and really rather an unexpected beauty to behold.

Very easy to care for. Grows slowly, the yellow coloring is spectacular and cheerful. Mine is growing perfectly content in near total shade (north side of house, may get 2-3 hours of dappled sunlight a day).

Remove stems with no variegation (solid green) to keep the color coming. I prefer not to shape it, just let it grow with natural spikes. If you insist on trimming/hedging, you may cut away the variegation, then what's the point?

Ours is bordering a flower bed and walkway, easy to take care of slow growing, We keep it compact.

A lovely plant to brighten up a dull area in dry shade. It is suitable for hedging. The small leaves will not look odd after clipping as some of the larger leaved varieties do.
It is also suitable to grow in sunnier spots and can only add charm and colour to its surroundings.
If kept well trimmed it can also be used on a container - very handy for providing winter cheer.
