Description
This hebe is a shrub reaching heights between one and two meters. Its evergreen leaves are dark green, shiny, and quite thick, usually measuring 2 to 5 centimeters long. The inflorescence is up to 8 centimeters long and densely packed with pale pink to bright magenta flowers. Each flower is just under a centimeter wide and has a short throat spreading into a four-lobed corolla. Two very long stamens protrude from the throat of each flower, giving the inflorescence a whiskery look. The fruit is a capsule containing flat, smooth seeds.
In cultivation
Hebe speciosa, its many cultivars and hybrids are very popular garden plants in area with suitably mild temperate climates. Many can even be grown outdoors in sheltered parts of southern Britain. They appeal because of their lush evergreen foliage, showy flowerheads, long blooming season and ease of cultivation.
Popular cultivars include the purple-flowered 'Alicia Amherst' and deep pink 'Simon Deleaux'. Hybrids includes cultivars of Hebe × andersonii (Hebe salicifolia × Hebe speciosa), especially the variegated 'Andersonii'; and Hebe × franciscana (Hebe elliptica × Hebe speciosa) cultivars such as 'Blue Gem' and 'Waireka'.
As of December 2013, the New Zealand Landcare Research considers that all forms of Hebe and Parahebe should be returned to the genus in which they were originally classified: Veronica. This appeared to be gaining general acceptance but recent research is indicating that divisions such as Hebe, Parahebe, Chionohebe, Leonohebe and Derwentia should be retained.
Flammability & building protection
Hebe speciosa is included in the Tasmanian Fire Service's list of low flammability plants, indicating that it is suitable for growing within a building protection zone.[1]
