Corokia
Corokia the generic name of this group of plants is an adaptation of the Maori name 'Korokio' They are a very useful set of plants for bonsai and I can not understand why you don't see more of them in displays.
Corokia are very hardy even under extremes, they will survive in almost any soil and situation where other plants would definitaly fail.
They have a very interesting branch structure and berry freely from an early age. Corokia thrive on regular trimming and respond well to shaping.
There are two main varieties that most other hybrids are taken from.
Corokia buddleoides
This is a very beautiful tree found in northland growing in association with Kauri trees. The leaves are a rich green with a silvery down on the underside. During November and December it has clusters of bright yellow flowers, these turn to dark red berries around August.
Corokia cotoneaster
This plant is used to cross with C. buddleoides to produce a hybrid called corokia x Vircata. This produces a shrub with contorted stems and branches, usually covered with black bark. The leaves are smaller but similar in colour to Corokia buddleoides. They have a profusion of yellow starry flowers in spring and summer, followed by red or yellow berries in autumn.
I have no idea why that thread was locked ?
I grow 4 corokia in my garden, cotoneaster and cotoneaster compact form, buddleoides which I use as a hedge and cheesmanii.
The wirery foliage of cotoneaster is called divaricating. New Zealand has a whole plethora of divaricating shrubs which evolved that way as a protection against grazing by moa birds.
I don't grow any of these plants as bonsai because they refuse to conform to the traditional styles which I like.
