How to Start It
★ Recommended for beginners
Hardwood cuttings root in warmth — the usual way to make more (it dislikes root disturbance, so pot on gently).
Blazing colour for hot, sunny spots — though the 'flowers' are actually papery bracts around tiny true flowers. The counterintuitive trick: bougainvillea flowers BEST when a little stressed — full blazing sun, lean soil, and kept on the dry side. Too much water and feed gives lush leaf and no colour. Frost-tender (to about -1°C), so it's a container plant wintered indoors in cold climates. Watch the thorns.

Planting & Sprouting
Growing Tips
- 1Sun, sharp drainage, and tough love are the recipe — bougainvillea rewards neglect and sulks on kindness (overwatering and overfeeding give all leaf, no colour).
- 2Grow it in a pot in cold climates so it can summer outdoors and winter indoors.
- 3Prune to shape after flushes, mind the thorns, and don't disturb the roots when repotting.

Harvesting
When to Pick
Bracts colour in flushes through the warm season; a dry spell triggers each flush
How to Harvest
- 1Let it dry out between waterings — that mild drought stress is what triggers the colourful bracts.
- 2Feed sparingly.
- 3Prune after each flush to shape it and encourage the next (flowers form on new growth).
- 4Handle with care: the stems carry sharp thorns.
- 5In cold climates move the pot somewhere bright and frost-free before winter.
