The word "clematis'' typically triggers images of multitudes of flowers smothering a beautiful climber, writes Robyn Abernethy.
Clematis is even derived from the Greek word for "climbing plant''. That is great when you have a wall, tree or bank for it scramble down or over, but for the smaller garden, there are shorter options, the bush or herbaceous clematis.
Clematis integrifolia has been in cultivation for centuries, and was introduced to gardens in England from southern Europe in 1573.
It grows up to 1m and most commonly has nodding velvety purple flowers, occasionally with white and rose forms.
Clematis recta is more sprawling and can reach up to 2m. The flowers are small, starry and white and produced in masses on the shoot tips.
It naturally sprawls through shrubs and other perennials along woodland margins in central and southern Europe, and central and western Russia.
In both species, the flowers are produced on the current season's growth, so it is best to prune hard to near ground level in autumn to allow new shoots to sprout from the base the following spring.
They are best grown among other plants in order to have the support of their neighbours.
Flowers are followed by the characteristic fluffy ornamental seed heads.
Clematis recta has been flowering at the Dunedin Botanic Garden for a fortnight, scrambling through foxgloves and witch hazel, with the shorter C. integrifolia coming into flower beside it.
They are in the border alongside Lindsay Creek just opposite the bandstand.
