Greater London area, UK:
Slower-growing and less invasive than the blue star creeper but with smaller flowers. Forms a nice mat (I grow it over small slate chippings) between a low wall and the lawn. It needs a barrier to stop it encroaching (by spreading fibrous, mat-like rhizomes) into the lawn. It has just two or three hours of sunlight from Spring to Autumn which is enough to flower, though not profusely. No disease problems in the three years I've grown it there. Partly dies back in winter - normally to -8C

White Star Creeper is a small, hardy, low growing, vigorous carpet forming plant covered with starry white flowers. The low growing nature lends itself to border edges or large containers where it is allowed to creep. It should survive normal winter conditions outside, especially if protected from the hardest frosts. Prefers partial shade with free-draining soil or compost.

This is a beautiful little plant for rockeries. However it develops brown patches that spread rapidly and the plant dies leaving only bare soil! On close investigation I find mycelia but spraying with funcide (Mancozeb) has not (to date) made too much difference. I fear that a year of careful tending is being lost in less than a month.

Any thoughts would be helpful.
