Description
A small upright shrub up to 1.8 m tall, woody and often quite branched. The leaves are linear-lanceolate, narrow, with serrated margins, up to 8–15 cm long. Flowers pink or lilac, tending to fade to whitish with age, forming a showy terminal inflorescence.
Propagation and growing
Plant at a spacing of 25 to 50 cm. It can be used on banks, in rock gardens, in pots on terraces and balconies, and even for cut flowers. It generally flowers between April and June. Feed with manure at planting and once a year at the same time as the garden's annual feeding. About 4 applications of mineral fertiliser can also be added during the flowering period.
Garden use
A species of great interest for ornamental use. Its water needs are moderate and it has a moderate to high need for hours of light. It grows best at mild temperatures (20–22 ºC) and adapts well to fertilised, well-drained soils. Its root growth is small, so there is no need to fear any destructive effect underground.
