Geranium palmatum
geranium
This perennial is semi-evergreen so it can lose some of its leaves in winter. In colder regions or more exposed gardens, it may lose them all, but then fresh new growth appears again in spring.
- Position: full sun or partial shade
- Soil: fertile, well-drained soil
- Rate of growth: average
- Flowering period: June to August
- Hardiness: half-hardy (may need winter protection)
Valued for both it's impressive, often evergreen foliage (which can develop a red flush in winter), as well as its showy clusters of magenta-pink summer flowers, this cranesbill will often self-seed in the right setting. Native to Madeira and the Canary Islands, it can be perennial if grown in milder regions or sheltered gardens, provided the soil is not too heavy and wet. - Garden care: Protect from frosts if grown outside, or move container-grown plants to a cool, sheltered site such as a coldframe or unheated greenhouse when the temperatures start to drop. In spring, remove any tatty looking foliage that has past its best, and then in midsummer, rejuvenate plants that are starting to look jaded, by trimming them back to encourage a fresh flush of new growth. Lift and divide large colonies in spring.
