A dwarf cultivar of the species, Kalmia latifolia "Elf" is in flower at present.
The petite flower buds set weeks before opening and are just as ornamental as the flowers themselves.
The pink buds are followed by a dainty cup-shaped pale pink flower which fades to white.
This evergreen plant ensures year-round interest with its somewhat dense and compact habit and shiny dark green leaves.
Although delicate in appearance, this wee plant can pack a real punch as the entire plant is highly toxic if ingested.
However, the toxic chemicals it produces also act as a natural insecticide; consequently, the plant is rarely troubled by pests.
Kalmia latifolia "Elf" can be used as mass planting in shrub borders and woodland gardens, and works well alongside rhododendrons and azaleas.
Kalmia can be quite a difficult plant to propagate.
Seed can be collected and sown in mid- to late winter, or it can be propagated from cuttings taken in late summer.
Seed should be scarified before being sown; this is to allow water to enter the seed to assist with germination.
