Scientific Names

Malvaceae >

Hibiscus >

syriacus >

A deciduous shrub growing to 3m by 2m at a medium rate.

It is in flower in September, and the seeds ripen in October^pf. The flowers are hermaphrodite (have both male and female organs) and are pollinated by insects^pf.

Cultivation

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and requires well-drained soil^pf. The plant prefers acid, neutral and basic (alkaline) soils^pf. It can grow in semi-shade (light woodland) or no shade. It requires moist soil^pf.

Prefers a well-drained humus rich fertile soil in a sheltered position in full sun^RH. Succeeds in any soil of good or moderate quality¹¹. Dislikes shade or badly drained soils¹¹. Plants grow best with their roots in cool moist soil and their tops in a hot sunny position. This species is hardy to about -20°c^RH but plants only really succeed in the warmer counties of Britain because of their late flowering habit¹⁸⁴. When planted in colder areas of the country, they will need protection for the first few winters^RH. The flowers only open in sunny weather²¹⁹. Plants rarely require pruning²¹⁹, though they respond well to pruning and trimming and this is best carried out in the spring or just after flowering²¹⁹. Plants are late coming into leaf, usually around the end of May or early June¹⁸². A very ornamental plant¹, there are many named varieties¹⁸².

Propagation

Seed - sow early spring in a greenhouse. Germination is usually fairly quick. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for their first year. Plant them out into their permanent positions in late spring or early summer. Some reports say that the seed can be sown in situ outside and that it gives a good rate of germinationTemplate:Pfaf78, 80, 113. Cuttings of half-ripe wood, July/August in a frame. Good percentage¹¹³. Cuttings of mature wood, early autumn in a frame. Good percentage¹¹³. Layering in mid summer to early autumn¹.
