Hebe speciosa, Carmichaelia williamsii, and Clianthus puniceus grow in an open position, or they can be deliberately planted in partial-shade for frost protection. C. puniceus should be pruned lightly after flowering, and it is generally beneficial to remove spent flowers from hebe bushes. The other shrubs on the poster, Chordospartium muritai, Hebe armstrongii, Pittosporum dallii, and P. obcordatum are hardy and easily cultivated in all parts of New Zealand. P. dallii is the most distinctive of the native pittosporums with its large, serrated leaves, but in cultivation it flowers only rarely. It is difficult to grow from cuttings, but can be grafted on to another species such as P. tenuifolium.
Seed germinates easily.
The leafless and erect growing C. muritai has the smallest flowers of our native legumes, but these are attractive as they are numerous and densely placed on erect inflorescences. The conifer-like H. armstrongii is exceptionally hardy and once established can be grown in most gardens. Large or woody plants of H. armstrongii can be rejuvenated by hard pruning as new growth readily shoots from old wood. The climbing daisy, Helichrysum dimorphum , has limited horticultural appeal, but is easily propagated by cuttings. It likes to scramble among twiggy shrubs, and it will eventually form a dense mat of stems on the top of such plants.
