A native of Peru and a tender perennial best
treated as an annual in Britain. Growing between
one and four feet high, the plant is shrubby with
oblong lance-shaped leaves and clusters of many
violet or purple flowers, famous for their pronounced
vanilla scent. There is a white form, and others
of garden origin.
The most successful method of culture consists
in lifting plants from the open ground in September,
wintering them in a warm greenhouse, and propagating
new stock from cuttings in early spring.
Seed sown early in March will produce vigorous
seedlings for planting out-of-doors in a sunny
and well-drained position in early June. These
will provide a good display in the same summer.
Also known as Heliotrope, this plant is an old
garden favourite and should not be omitted from
any summer bedding scheme.
Propagation is from seed or cuttings.
The flowering season is from midsummer onwards.
