Plumbago
Dot,
There are annual and perennial leadwort. Is your plant Ceratostigma
plumbaginoides? (I have a penchant for using formal names, but in this
case it's really much easier to call it plumbago or leadwort.) It's
supposed to be mildly invasive, but mine isn't spreading very quickly.
It's planted on a slope, so I assume that it is not getting quite as
much water as it would like.
This is from Encyclopedia of Perennials by Christopher Woods:
Grow in full sun or partial shade in ordinary, well-drained
soil.
Propagations: Divide in spring. Take stem cuttings in
midsummer.
[C. plumbaginoides] is a good groundcover for a lare area,
although it comes in leaf late in the spring. Divide every few
years if the clumps begin to thin out. Makes an excellent
groundcover for areas planted with Crocus bulbs, coming into
leaf as the bulbs fade. Zones 5-8.
