Je n'ai jamais pu garder d'autres espèces de Gardenia ( Gardenia augusta ou jasminoides , Gardenia tahitensis ou Tiare ), au bout de deux trois ans, ils dégénèrent, il leur faut un climat plus humide et plus chaud, alors que ce Gardenia thunbergia demande le même climat que mon jardin.
La bouture de ce Gardenia ne me sempble pas évidente, sur l'encyclo de plantes sud-africaines , ils préconisent l'été pour le faire, oui, mais leur été ( janvier février ) ou le notre ?
Pour l'instant, mes boutures végètent, mais sont toujours vivantes.
Gardenia thunbergia is a beautiful flowering shrub or small tree, with showy, heavily perfumed flowers and decorative fruits.
Description
This is an evergreen shrub or small tree, 2 to 5 m in height, with a smooth, whitish, usually straight main stem up to 250 to 300 mm in diameter, and short, rigid branchlets. The leaves are carried in whorls of 3 or 4 crowded near the ends of the branchlets. They are a glossy light green, hairless, softly to thinly leathery and conspicuously veined. Simple with an entire, wavy margin, variable in size, up to 140 x 60 mm but usually smaller, mostly oval, tapering abruptly to a rounded or blunt tip while the base tapers onto the stalk.
The flowers are large, showy, creamy white and heavily perfumed, particularly at night. They open from elegantly furled creamy-green buds. The flowers do not turn yellow as they age on the bush. The corolla is a 70-120 mm tube with 8 large lobes spreading to ± 80 mm in diameter. Flowers are produced abundantly during summer (October to March), peaking in late summer (January to March).
The fruits are hard and woody, and heavily fibrous inside, and where not being browsed by large antelope, can remain on the bush for years. Each fruit is egg-shaped, greyish green, 50-75 x 35 mm, when mature roughly dotted with whitish encrustations.
