Lupins are traditionally a feature of informal cottage gardens,
but their tall spires in a range of soft colours make a striking
contribution to the border in any garden design. The most
reliable types are hybrids of the species L. polyphyllus.
GROWING Set out young plants in early spring or in
the autumn, in light, slightly acid soil. Neutral soils will
do, but lupins hate lime, and in heavy soils the stems become
too soft to support the flowers. Stake with twiggy sticks
when plants are 15cm/6in high. Wait until late winter before
cutting back, to prevent water lodging in the hollow stems.
PROPAGATION Take 7.5cm/3in cuttings, with a little
rootstock attached, in spring. Insert in sandy soil in a cold
frame; pot on when rooted or set in nursery rows before planting
out in the autumn. Named varieties do not come true from seed.
VARIETIES Choose forms of the Russell lupin strain.
Many are bi-coloured. `Blushing Bride', cream and white; `Cherry
Pie', crimson and yellow; `Jane Eyre', violet and white; `Lilac
Time', rose-lilac and white; `Limelight', butter yellow; `Guardsman',
vermilion.
POSSIBLE PROBLEMS Crown rot, root rot, honey fungus.
