About Great Bougainvillea
Botanically, Bougainvillea spectabilis is a fast-growing climber in the Nyctaginaceae family. It reaches around 10 m tall and 6 m wide at maturity, with evergreen foliage. Red, orange and purple flowers appear for much of the year.
Where to grow Great Bougainvillea
Great Bougainvillea suits tropical, subtropical and warm-temperate climates and grows best in full sun. It is frost tender, so protect it from hard frosts or grow it in a sheltered spot or pot. It also tolerates salt-laden coastal winds and is a genuinely water-wise choice.
Soil & planting
Great Bougainvillea does best in sandy, free-draining and poor soil. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool. For a screen, space plants about 3.6 m apart.
Watering & feeding
Great Bougainvillea performs well with relatively little water once established. A light spring feed is usually enough to maintain steady growth. Keep a newly planted specimen evenly watered through its first season; established plants can then follow the water needs above.
Pruning & care
Prune Great Bougainvillea after flowering to keep it compact and encourage the next flush of blooms. It clips well, so trim two or three times a year for a formal finish. Expect a moderate maintenance care workload once it is established.
Using Great Bougainvillea in the garden
Great Bougainvillea earns its place for a fast screen or informal hedge, a feature or specimen planting and holding soil on banks and slopes.
Companion planting & design
For easier irrigation and care, group Great Bougainvillea with species that also favour happy on low water and tropical climate. Leave enough room for the mature spread so neighbouring plants are not crowded out.
Good to know
It is thorny — useful as a barrier, but wear gloves when pruning.
