Calonyction aculeatum
Ipomoea bona-nox
From tropical America, this fast-growing, soft-stemmed, evergreen
perennial vine grows up to 22 ft (7 m) or more. It is cultivated for
its large, fragrant, silver-white flowers, which are borne in summer
and open at night.
Cultivation: They prefer moderately fertile, well-drained soil and a
sunny position. Care should be taken when choosing species, as some
can become extremely invasive in warm districts.
Propagate in spring from seed which has been gently filed and
pre-soaked to aid germination, or from cuttings in summer (for
perennial species). |
