Callistemon citrinus Splendens


crimson bottlebrush 'Splendens'

Unusual bottlebrush-like flowers

An exotic looking shrub that is easy to grow in a sheltered spot and perfect for giving a luxurious feel to a planting area. The flower spikes really do look like pink bottlebrushes.


Any sunny spot in moderately fertile, well-drained soil will do nicely. Despite their tropical origins they can be grown outdoors in a sheltered position. They also grow well in large pots that can be moved into a bright frost-free greenhouse if harsh, cold weather threatens.


Bottlebrushes are quite hardy in milder parts of the UK and in coastal areas they can grow into substantial plants that need little attention. Pruning after the flowers are over will keep them bushy and looking good.

Bottlebrushes are native to temperate parts of Australia and naturalised elsewhere

Planting instructions

Choose a container, with drainage holes at least twice the size of the one the plant is currently growing in. Place stones, broken up flowerpots or polystyrene in a thin layer over the holes to help with drainage. Place a layer of multi-purpose compost on top. Remove the pot and position the plant so the top of the rootball sits 2.5cm below the rim of the pot. Fill around the rootball with compost, firming as you go. Water in well and keep well watered especially through dry spells.

Planting site Patio container, City garden, Mediterranean garden
