Flowers mid summer to early autumn
One species of mallow (Lavatera trimestris) and its varieties are grown as annuals. This is a bushy plant some 60-90cm (2-3ft) high with attractive trumpet-shaped-like coming in shades of pink and white. These appear during the summer months, and are shown off to best effect in herbaceous borders.
Several varieties have been developed from Lavatera trimestris, including the following:
‘Loveliness’ is an old variety producing rose-pink flowers in late summer and early autumn. The plants are 90cm (3ft) high.
‘Mont Blanc’ has glistening large white flowers in mid summer on dwarf compact plants, 50-60cm (20-24in) high.
‘Ruby Regis’ grows 60cm (2ft) high and bears a profusion of large, deep cerise-red flowers.
‘Silver Cup’ has bright pink flowers shaded silvery pink. It stands 60cm (2ft) high.
‘Tanagra’ has large glistening cerise-pink blooms. It is a tall variety reaching 90cm (3ft).
Sow mallow directly in its flowering site in early autumn or, just covering the seeds with soil. It will flourish in most well-drained garden soils though rich soils should be avoided as they encourage leafy growth at the expense of flowers. Thin out the seedlings to 45cm (18in) apart in mid spring.
Mallow seeds itself freely and produces plants the following sea-son if the soil around is left undisturbed.
