Otacanthus caeruleus

 

Little Boy Blue

Soft shrub to 1 m. Bright blue flowers spring-autumn. Needs full sun. The vibrant blue flowers are two-lipped, with the lower lip sporting a white streak at the throat. The flowers grow in whorls around the end of the stem. When growing, the weak, lanky stems may need some support if you want a neater shape. Well drained soil, full sun, water moderately; propagate using cuttings.

Planting young plants

From Early Spring TO Early Spring

Best when mass planted to provide a wall of summer colour. Needs a moist but well drained soil and should be planted in a sunny position. Stems can be battered and broken by strong wind so will either need supporting with canes when mature or the protection of a wall or fence, but do not deprive them of sunlight.
