Characteristics |
Uses |
| Salix matsudana |
PN 227 |
Tolerates drier soils than most other willows; develops early rough bark. Large spreading tree becoming prone to wind damage with age. Moderate susceptibility to leaf rust. Female |
Soil conservation, shelterbelts (requires side trimming) |
| S.matsudana |
Shanghai (PN 695) |
Faster growing than PN 227 but similar drought tolerance and early rough bark formation. Broad crown, best planted in gullies and form pruned to reduce wind breakage. Moderate susceptibility to leaf rust. Female. |
Soil conservation. |
| S.matsudana |
Tsinan (PN 694) |
Similar to PN 695 but faster growing and more susceptible to wind damage. Has less palatability to possums in the second year after planting. Moderate susceptibility to leaf rust. Female. |
Soil conservation. |
| S.matsudana x alba |
Adair (NZ 1143) |
Reasonably narrow crown; leafs out early in August. Male. |
Soil conservation, shelterbelts, river control. |
| S.matsudana x alba |
Aokautere (NZ1002) |
Susceptible to Marsonnina leaf spot disease and not recommended for humid areas. Fairly narrow crown, less susceptible to wind damage than PN 227 parent. Male. |
Soil conservation. |
| S.matsudana x alba |
Hathaway (NZ 1317) |
Growth rate and form intermediate between NZ 1130 and NZ 1149. Has a degree of possum resistance. Male. |
Soil conservation, river control, amenity. |
| S.matsudana x alba |
Hiwinui (NZ 1130) |
Rather spreading crown and pendulous lower branches. Male. |
Soil conservation, river control, bee forage, amenity. |
| S.matsudana x alba |
Moutere (NZ 1184) |
Fast growing, reasonably narrow crown. Good for erosion control on streambanks, in gullies and on foot slopes. Male. |
Soil conservation, shelterbelts, river control. |
| S.matsudana x alba |
Tangoio (NZ 1040) |
Better form for shelter and not as vigorous as other hybrids. More drought tolerant than Moutere and more suitable for planting on hillsides. Female |
