Rock Garden Plants A to Z:
BACK
Lithospermum- (Gromwell)
Lithospermum diffusum
'Heavenly Blue' |
Lithospermum (or lithodora) is a ground cover plant with creeping
stems and clothed with slender leaves. A mass of open-faced funnel-shaped
flowers appear in summer. The color of the popular species and its varieties
is Gentian blue- as bright as anything you will find in the summer rock garden.
Lithospermum requires a sunny spot and humus-rich soil. Do not grow
L.
diffusum if your soil is chalky - choose instead the lime-tolerant
L.
oleifolium.
VARIETIES:
The favorite Cromwell for the rock garden is
L. lothospermum deiffusum (Lithodora diffusa)
- height 6 in., spread 2 ft., flowering period June-September. Its
outstanding feature is the pure blue of its flowers. Two named varieties
rather than a species are grown
-'Heavenly
Blue' and
'Grace
Ward'. Both are very similar despite the claim of obvious differences
in some catalogues.
L.
oleifolium is quiet different- the leaves are silvery-grey and the pink buds
open into pale blue
flowers.
SITE
& SOIL:
Well-drained moist soil in full sun is essential.
PROPAGATION:
Plant stem cuttings in a cold frame in midsummer.
