Hibiscus Syriacus ‘Rubis or Rose Mallow

Hibiscus Syriacus ‘Rubis’

Rose Mallow

Malvaceae

hibiscus-syriacus-'rubis'

The generic name was used already in Ancient Greece (ibiscos) and Rome (hibiscus). Its origin is not clear, but may be derived from the sacred Egyptian Ibis. The genus comprises over 200 species found mostly in tropical regions. Many are of practical use in commerce, yielding essential oils, oily seeds and fibres.

Hibiscus syriacus from China and India is the only species grown in gardens. It has given rise to many garden varieties, of which ‘Rubis’ is one. This variety is a deciduous shrub about 3 m (10 ft) high with short-petioled, rhombus-shaped leaves, 5 to 10 cm (2 to 4 in) long, sometimes three-lobed with three prominent veins. The short-stalked flowers are borne singly; they have five petals which are curled in the bud. The flowers of this form are red or wine-red, dark at the centre and with dark veins. There are usually a great many stamens which fuse to form a tube at the base. The flowering period is from August to September.

Hibiscus, or rose mallows as they are called, are readily propagated by means of seeds which are sown directly in the flower-beds in spring and have very good powers of germination. The young seedlings, however, are somewhat tender and should therefore be protected against frost. They may also be propagated by summer cuttings, taken with a heel. Garden forms are generally grafted and grown for one year in pots, which are put in a cold greenhouse or deep frame for the winter.
