Description
Lavatera Twins Cool White is an annual variety with a bushy habit that stands out for its good disease resistance. It forms a branched clump of healthy foliage and is covered for three months with lots of round, white calyx flowers with satin-like reflections. This easy-to-grow plant combines many qualities. Sow it under cover or directly in moist, well-drained soil, in beds of annuals, perennials, or in pots.
Lavatera trimestris is a tender annual mallow native to the Mediterranean region. It is a cousin of wood mallows (Malva sylvestris) or marshmallow (Althea officinalis), belonging to the same family of malvaceae. The Twins Cool White variety has been selected for its resistance to rust and its compact habit. It quickly forms a small, branching bush with bright green to bluish leaves, reaching 45 cm (18in) high and 35 cm (14in) wide. The basal leaves are almost round, while those that cover the stems have palmate lobes, resembling maple leaves. It will bloom from June to September (earlier in warm climates) with pure white and satin-like, veined flowers of a good size (6 cm (2in) in diameter), solitary in the axils of the leaves. They will not last long but continuously renew themselves on the plant, especially if faded flowers are regularly removed. The large seeds contained in their black capsules are easy to grow when mature.
Annual mallows are essential in "cottage gardens", but varieties with vibrant colours easily fit in "mixed borders", beds of annuals alongside cornflowers, cosmos, or perennials such as flax, asters, or gauras. A single packet of Lavatera trimestris seeds can decorate several beds, with very fresh colours. Large-flowered lavateras are also good cut flowers. Small varieties like Twins Cool White look lovely in pots, mixed with sweet peas or snapdragons.

Planting and care
Annual mallows are sown in spring, directly in the ground, when temperatures start to warm up (germination occurs at 15°C (59°F)). Light promotes seed germination. You can also sow them in indoors in March and then transplant the young plants outdoors from May, once the last frost has passed. When the young plants reach about 20 cm (8in) high, pinch the main stems to encourage branching. Leave at least a 40 cm (16in) gap between plants.
Choose a well-exposed location, in full sun, and regular, well-drained soil to grow them in. Soil that is too rich will favour leaf growth at the expense of flowering.
For a beautiful flowering, the soil should remain moist, even humid, but without stagnant water. Mulch around the plants and water occasionally, especially during hot and dry summers.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
