Gardeners' Notes:

Positive Dave_in_Devon On Sep 7, 2008, Dave_in_Devon from Torquay
United Kingdom (Zone 9b) wrote:

A hybrid between P. myrtifolia and P. oppositifolia, I've found this to be a very rewarding small shrub (up to 1.5m) for growing in the milder coastal regions of southern England. The foliage is a very pleasing silvery blue-green, which forms a perfect backdrop to the striking magenta flowers. Here it flowers for a good 8 months of the year when well established and can flower almost continuously in mild-winter years.

Mine has withstood lows of -2C (28F) followed by days when temps failed to rise above 5C (40F) without any hint of damage and it can cope quite severe gales coming in off the sea.

It does very well in a well-drained, sandy soil and seems to be moderately drought resistant, although growth and flowering will be affected. Full sun at this latitude is essential in order to promote free flowering, although it will grow away quite well in light shade.
