Growing false heather
Position. Full sun, by the North Carolina State toolbox, which says it takes high summer heat. The New South Wales flora records it from moist sites.
Soil and water. The toolbox says it adapts to most soils with good drainage, clay, loam or sand, withstands some drought but grows best with regular moisture, and is moderately salt tolerant. These are American observations; no Australian reference read grades it.
Climate. The toolbox gives USDA zones 9a to 11b and says that in cold weather it dies back to the ground in its cooler zones, sprouting again from the base if it was well mulched; where winters are colder it is grown as an annual, a container plant or a houseplant. No Australian reference read gives a frost figure.
Flowering. The New South Wales flora gives late winter to spring; HortFlora, the horticultural flora of south-eastern Australia, summer to autumn; the toolbox says it flowers profusely from summer until frost. Bees and butterflies visit the flowers, by the toolbox.
Pests. The toolbox lists mealybugs, thrips and whitefly, mostly on indoor plants, flea beetles that can strip the leaves quickly, and nematodes that weaken plants.
Propagation. From seed or softwood cuttings, by the toolbox.
In Australia. The New South Wales flora calls it widely cultivated and occasionally escaping from cultivation, and the Australian Plant Census records it as doubtfully naturalised in New South Wales. The NSW WeedWise list, as read, has no entry for it. The toolbox notes it has naturalised in New Zealand and Hawaii and is considered weedy in Hawaii.
Using false heather
The North Carolina State toolbox suggests false heather for borders, edging along walkways, groundcover, mass plantings and hedges, and for containers and hanging baskets on a patio. For spacing, the toolbox's table gives only an 'available space to plant' band, not a planting distance; its spread of 0.2 to 0.8 m is the figure to work the centres from. HortFlora names seven cultivars sold in south-eastern Australia, among them Rob's Mauve, Golden Ruby and Star White, and growers also list a mauve form with its own page.
What to check before you buy
Check the flower colour on the line: the species is lilac to purplish pink, and the North Carolina toolbox notes cultivars with white and with pink flowers. The North Carolina toolbox says plants are best replaced every year where it is grown as an annual; in a frost-free garden it is a small evergreen shrub. The table above shows the sizes growers list. The guide to nursery plant quality covers what to check in the roots, canopy and for pests before stock leaves the grower. Stock that crosses a state border travels under that state's biosecurity rules.
