Often seen on exotic holidays in tropical or subtropical areas of the world, jacaranda can be grown in temperate regions as a foliage plant; outside in summer and overwintered in greenhouses and conservatories.
Common name: Green ebony tree, jacarandaBotanical name: Jacaranda mimosifoliaGroup: Conservatory or greenhouse plant (trees, shrubs and woody climbers)Flowering time: Mid spring, rarely in the UKPlanting time: SpringHeight and spread: 15m (50ft) by 7-10m (22-30ft)Aspect: Bright light under glass, full sun outsideHardiness: Frost tenderDifficulty: Easy
Although jacaranda will outgrow their space relatively quickly, they make great foliage plants until then. Sometimes flowers form on potted specimens when they reach the 1.8m (6ft) mark, but in the UK, this is rare.
Grow outside in summer or in a greenhouse or conservatory. Not being hardy, the winter minimum night temperature needs to be at least 5°C (40°F). They will lose their leaves at this temperatures, but it is best to let them become dormant. Warm conditions with low light levels would encourage legginess. They are not good houseplants.
Jacaranda can be propagated by either by cuttings or seeds.
Take semi-ripe cuttings of young growths in early summer and insert the cuttings into pots of cuttings compost and into a propagator with bottom heat of 20–24°C (68–75°F).
Jacarandas can be raised easily from seed each year for use as foliage plants.
It is unusual to get cultivated forms of jacaranda but the species Jacaranda mimosifolia - widely grown in warmer regions and familiar to many from holidays to such parts - is available in the UK.
