(Redirected from Calonyction aculeatum)
'''Ipomoea alba''', sometimes called the 'moonflower' (but not to be confused with the other species also called
moonflower) or 'moon vine', is a species of night-blooming
morning-glory, native to tropical and subtropical regions of the
New World, from northern
Argentina north to
Mexico and
Florida.
It is a
perennial herbaceous liana growing to a height of 5-30 m tall with twining stems. The
leaves are entire or three-lobed, 5-15 cm long, with a 5-20 cm long stem. The
flowers are fragrant, white or pink, and large, 8-14 cm diameter. The flowers open quickly in the evening and last through the night, remaining open until touched by the morning sun.
The name Moonflower derives because they bloom in the evening, and are round in shape like a full moon.
Historical use
The ancient
Mesoamerican civilizations used the ''Ipomoea alba'' morning glory to convert the
latex from the
Castilla elastica tree and the
guayule plant to produce bouncing
rubber balls. The
sulphur in this morning glory served to
vulcanize the rubber, a process pre-dating
Charles Goodyear's discovery by at least 3,000 years.

Cultivation
The species is widely cultivated as an
ornamental plant for its flowers. In areas too cold for winter survival, it can be grown as an
annual plant. Propagation is usually by seed. The seed should be nicked with a file and then soaked overnight before planting. In some areas it is an
invasive species which can cause problems in agricultural settings.
