Cultivation Details
Corynabutilon ochsenii is a plant of the warm temperate zone in Chile and can tolerate occasional temperatures down to between -5 to -10°c, especially when grown in a warm, sunny, sheltered position[1, 2, 3]. The plant can be cut back in cold weather, but will often resprout when the warmer weather returns and that new growth is able to flower freely in the summer[PFAF]. Requires a sunny position or part day shade in a fertile well-drained soil[3]. Dislikes drought[3]. Plants can to be short-lived, dying suddenly without any apparent cause. This is probably because they flower so profusely that they die of exhaustion[1]. They produce an abundance of fertile seed, however, and this normally breeds true to type, though it will hybridise with the closely related Corynabutilon vitifolium if this species is nearby[1]. Dead-heading plants to prevent seeding can enhance longevity[3]. Tip-prune young plants to promote a bushy habit, older plants can be cut back hard annually in spring if required[3]. Plants in this genus are notably resistant to honey fungus[3].
Propagation
Seed - sow spring in a greenhouse[3]. Germination should take place within a few weeks. Once the seedlings are large enough to handle, prick them out into individual pots. Grow them on for at least the first winter in a greenhouse and plant out in late spring or early summer, after the last expected frosts. Cuttings of young shoots, early summer in a frame[3]. Grow on in the greenhouse for their first winter and plant out in spring after the last expected frosts. Cuttings of half-ripe wood, mid summer in a frame[3]. Grow on in the greenhouse for their first winter and plant out in spring after the last expected frosts.
