Cultivation and Uses
USDA hardiness zones: 4-9.
Heat tolerant: Yes.
Drought tolerant: Yes.
Sun: Full sun to light part shade. This plant does best in full sun and is intolerant of heavy shade.
Planting: Locate this plant in full sun, in unamended soil that drains rapidly and is normally dry. An elevated rocky location is ideal, hence the name "Stonecrop". Several plants may be spaced 6-10" apart. This plant cannot compete with more rapidly growing plants, so be sure to remove any weeds and other plants within three feet.
Soil: Well drained, dry, low in organic content. This plant is tolerant of most soil types. Fertilization is not required.
Water after becoming established: Monthly, less often with rain. White Stonecrop is susceptible to root rot in poorly draining soil or when overwatered.
Prune: Sterilize cutting tools with 70-100% isopropyl alcohol before using. Cut back dead or damaged stems at any time. Remove dead flower stems as desired.
Litter: Very low.
Propagation: Seed, offsets, leaf and stem cuttings. Sterilize cutting tools before using. Cut an offset close to the mother plant to get as much root system for the offset as possible. Cuttings must be allowed to callous over in dry air first. Afterwards, they can be half immersed in dry soil and will produce roots within a few weeks.
Uses: An ornamental plant for a rock garden, xeric garden, or container.

Comments
