Hebe ‘Joanna’ is a compact, erect branched, evergreen shrub, growing up to 40 in (1 m). The green, spear-shaped leaves are 0.8–1.2 in (2–3 cm) long, and not glossy. The flowers are pale lilac-pink; summer. A hebe fairly hardy in the UK.
This hebe cultivar was raised by Graham Hutchins of County Park Nursery in 1995, and named after his granddaughter. The parents of Hebe ‘Joanna’ are probably Hebe traversii and one of the Carnea group.
