Several dwarf relatives of the Buttercup are grown in the rock garden – the taller types belong in the border. But the dividing line between the twois not clear-cut – R.ficaria’Aurantiacus’andR.gramineus are used as either tall rockery specimens or f ront-of-the-border plants. Add some sharp sand or grit to the soil before planting.
VARIETIES: R. calandrinioides produces large whiteabove the greyish green – height 6 in., spread 6 in.
Flowering period: February-April. R. gramineus blooms later (May-July) and its bowl-shapedare yellow. The shiny blooms are borne in loose sprays above the grassy, bluish leaves. The plant is quite large – height 1 ft. spread 1 ft. R. montanus is a neat dwarf – height 4 in., spread 4 in., yellow flowers in spring.
SITE AND SOIL: Well-drained soil and sunny site are essential.
PROPAGATION: Sowunder glass in spring or divide clumps in autumn.
