species from India, China and Malaysia is an erect, bushy annual
that grows fairly quickly to a height of 12Ð18 in (30Ð45 cm) with a
spread of 8Ð10 in (20Ð25 cm). It has lance-shaped bright green
leaves and produces small, camellia-like single or double spurred
flowers throughout summer and early fall (autumn). Colors include
blood red, purple-red, pink and white; some flowers are spotted.
Impatiens balsamina is marginally frost hardy and is a good species
for bedding displays in sunny situations.
Hardiness zone from 9 To 12
Cultivation: Fully frost hardy to frost tender, they will grow in
sun or part-shade; many species do well under overhanging trees.
They prefer a moist but freely drained soil, and need protection
from strong winds. Tip prune the fast-growing shoots to encourage
shrubby growth and more abundant flowers. Propagate from seed or
stem cuttings in spring or summer.
