It is a vigorous climber with scented flowers and deep green foliage.It produces white male and pale purple female flowers in spring and sometimes red to purple fruit are produced in late summer.Plant in good soil in sun to light shade out of cold drying winds.15-20ft(5-6.5m) evergreen.

Physical Characteristics

Holboellia latifolia is an evergreen Climber growing to 4 m (13ft 1in).
It is hardy to zone (UK) 9. It is in leaf 12-Jan It is in flower in March. The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant)

USDA hardiness zone : 8-11

Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in full shade (deep woodland) semi-shade (light woodland) or no shade. It prefers moist soil.

Habitats

Woodland Garden Sunny Edge; Dappled Shade; Shady Edge; not Deep Shade; 

Edible Parts: Fruits

Fruit - raw[51, 177, 272]. A mealy texture and often considered to be insipid[2, 146, 243], though it is considered to be very palatable in the Himalayas[183]. The fruit is large[105], purple, sausage-shaped with many black seeds in the white pulp[183].The fruit is up to 10cm long[200].

Cultivation details

Easily grown in any fertile soil in sun or part shade[182, 200]. Plants grow best on a shady wall or when grown into a tree[200]. They succeed in sun or deep shade, but fruits are much more likely to be produced when the plants are grown in a sunny position[200, 219]. Plants are not fully hardy in Britain, they tolerate temperatures down to about -15°c[184] and can be damaged by prolonged periods below -5°c[200]. A plant outdoors between two greenhouse at Cambridge Botanical Gardens was thriving in 1989[K]. Plants thrive in S.W. England[11, 59] but do not fruit freely in this country[11]. Plants at Dartington Hall in Devon occasionally produce fruit[11]. Hand pollination would probably help[11, 166], fruits are more likely to form in hot summers[166]. There is also some doubt as to whether the plants are monoecious or dioecious, it would be best to grow at least two distinct plants (not cuttings from one plant) and make sure that male and female flowers are present[K]. The flowers are sweetly and heavily scented. The males are produced on the previous years wood whilst females are produced on the current years wood[182]. Plants are fast growing[200] and climb by means of twining[182]. Closely related to H. coriacea[11]. This genus is closely related to Stauntonia spp[200].

Propagation

Seed - we have no details on this species but suggest sowing the seed as soon as it is ripe if this is possible, otherwise as soon as you obtain it, in a warm greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of softwood[1]. Cuttings of half-ripe wood in late summer or autumn.
