Trees (New Zealand Native) Hebes hybrids & cultivars with photos
Below are some of the Hebes and their cultivars and hybrids that are grown in New Plymouth
Hebe is the largest genus of New Zealand shrubs containing almost 80 species, many of which hybridise. It is typically a New Zealand genus and there are only about 100 species known.
Hybridisation between species growing in the wild is not common but when compatible species are in planted in gardens, hybridism is extensive. Many growers and collectors have selected and named these cultivars. Planned breeding of ornamental Hebe cultivars has been happening for a long time. It is thought that the first hybrid was produced in 1845 in Suffolk, England and it is now estimated that there are around 700 hybrid Hebes.
The Royal New Zealand Institute of Horticulture is the International Registration Authority for Hebe and they have been working steadily towards a Register of cultivar names for the genus Hebe for many years. It contains a number of cultivar names which are now of historical interest.

Another site to visit is "The Hebe Society" which was founded in 1985 and is a British Registered Charity. It is affiliated to the Royal Horticultural Society, New Zealand Alpine Garden Society and Tatton Garden Society.
What's the difference between "hybrids" and "cultivars"?
The anwser from Australian Native Plant Society web site
Well, as far as ornamental plants are concerned, a hybrid is usually a cultivar; but a cultivar doesn't have to be a hybrid!
The word "cultivar" is short for "cultivated variety" and a cultivar is a selected form of a plant that has some desirable characteristic for cultivation. It is often given an attractive name by an enterprising horticulturist with the hope of commercial success. The desirable characteristic might be flower colour, growth habit, foliage characteristic, disease resistance or anything else. The cultivar may be an unusual form of a pure species that was discovered in the wild, a form that arose in a batch of seedlings in a nursery or a hybrid...so a cultivar doesn't have to be a hybrid.
A hybrid is a genetic "cross" between two different species (usually within the same genus) or between a species and other hybrids. Hybrids can occur naturally or they can be produced by human intervention. The aim of deliberate hybridization is to produce plants with desirable characteristics. If the hybridization gives successful results, the plant is usually given a cultivar name and released commercially....so, a successful hybrid is also a cultivar.
