Gardeners' Notes:

Positive RosinaBloom On Oct 26, 2012, RosinaBloom from Waihi
New Zealand (Zone 1) wrote:

Senecio serpens is a succulent which has cylindrical glaucous blue leaves, grooved above and blunt tipped. In very dry conditions the leaf tips can change colour to a purplish shade. Tight heads of small cream flowers are held above the foliage.They can reach heights up to 15cm, and their blue colouring contrasts well in group plantings. The flower stems need to be removed to keep a tidy appearance. They seem to do well in part shade such as at the base of trees, are easy to grow, and are very tolerant of poor soils.

Great looking iceplant for Warmer areas of Southern California (slightly frost tender). Nearly white, but usually a blue-white coloration. Can rub off the tomentum and it's a blue-green beneath. CAn be a bit invasive, but very easy to control but just cutting it back.
