Callistemon (Bottlebrush) [42] These evergreens are ideal for the cool conservatory where they will appreciate plenty of light. The two forms shown can be grown outside in a sunny, sheltered position where they would be able to tolerate light frost.
C.lanceolatus [483] Forms a dense mass of dark green very narrow leaves which can give off a lemon scent when crushed. The crimson flower spikes can appear throughout the summer.
