Propagation
Sow fresh seeds during autumn and place in a protected environment to germinate. Seedling variation occurs regularly and seeds are prone to fungal attack.
Semi-hardwood cuttings of non-flowering shoots taken from late summer to early autumn and placed in a protected environment with bottom heat.
Botanic information
Leaf: The variable sessile leaves are long lanceolate to oblong lanceolate up to 20 mm (µ in) wide with an accumulate apex. The dark green leaves have a fleshy texture and are arranged slightly asending to spreading along the stems.
Flower: The tubulate flowers have a very short pedestal with a narrow glabrous calyx lobes with an acute apex. The corolla tube opens with spreading narrow-ovate petals and has exserted stamens in the centre. They are arranged densely in a raceme that may be pendant and varies in length up to 200 mm (7µ in)by 25 mm (1in) in diameter. The axillary inflorescence appears towards the end of the branches amongst the foliage during summer.
Fruit: The long ovoid nut is a glabrous with an acute apex and contains numerous seeds. The small seeds are viable but the plant is commonly reproduced vegetatively to maintain true to type.
General information
Hebe requires an annual light prune to maintain a compact habit. If the plant becomes leggy a hard prune may result in dieback of the plant.
Hebe grows and produces more flowers in full sun, but will tolerate some shade. They are generally pH adaptable preferring and organic rich moist soil but care must be taken not to allow the roots to dry out. They also tolerate cold conditions and a widely cultivated in the UK and parts of the USA.
