A genus of showy perennials found in various
parts of china and Central Asia.
The foliage is elegant and fern-like, comprising
many segments borne on stems sometimes a foot
long. The flowers are trumpet-shaped, open at
the mouth and two to three inches long, and of
a similar width.
Incarvillea delavayi, from China, carries up to twelve
flowers of rosy-purple on two-feet stems.
Incarvillea grandiflora, from China, has its flowers either
solitary or in pairs and of a deep rose shade.
Incarvillea lutea has up to twenty yellow flowers, two inches
across, of a pendulous habit. Incarvillea olgae, from Turkistan,
has flowers of only one and a half inches in length
and a pretty pale pink shade.
In order to enjoy the fine foliage and general
elegance of a well-grown plant of Incarvillea
it is necessary to provide a light, sandy soil
that has been enriched with decayed manure, and
plant young stock from pots.
The position should be warm and fully exposed
to the sun, but protected from cold winds.
It is wise to afford some protection during winter.
Propagate by division of the root in late winter
or from seed.
The flowering season is in May and June.
