About Lasiandra
Botanically, Tibouchina lepidota 'Alstonville' is a fast-growing shrub in the Melastomataceae family. It reaches around 4 m tall and 3 m wide at maturity, with evergreen foliage. Purple flowers appear in autumn.
Where to grow Lasiandra
Lasiandra suits subtropical, tropical and warm-temperate climates and grows best in full sun and part shade or morning sun. It is frost tender, so protect it from hard frosts or grow it in a sheltered spot or pot.
Soil & planting
Lasiandra does best in acidic, free-draining and loamy soil. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Lasiandra does best with regular, moderate watering. A light spring feed is usually enough to maintain steady growth. Check moisture below the mulch during establishment and water thoroughly when needed rather than following a rigid schedule.
Pruning & care
Prune Lasiandra after flowering to keep it compact and encourage the next flush of blooms. Expect a moderate maintenance care workload once it is established.
Using Lasiandra in the garden
Lasiandra earns its place for a feature or specimen planting and drawing nectar-feeding birds into the garden.
Companion planting & design
For easier irrigation and care, group Lasiandra with species that also favour regular, moderate watering and subtropical climate. Leave enough room for the mature spread so neighbouring plants are not crowded out.
