Planting list
Canopy trees
Primary functions: wind shelter, leaf litter.
Black Alder (Alnus glutinosa). Fast growing, wind tolerant, deciduous. Nitrogen fixing.
Walnut (Juglans regia cultivars). Vulnerable to strong winds, deciduous. Pairing with a nitrogen-fixing tree (e.g. Alder) provides shelter and increased growth. Wind-pollinated, usually dioecious; nut production requires several trees of compatible cultivars.
Willow (Salix spp.). Fast-growing, wind-tolerant, deciduous. Prefers proximity to waterways. Can be invasive if left unattended; on the other hand canes can be planted in winter and grown into hedges, fences, and archways. Crop: canes, spring.
Mulberry (Morus spp.). Large, wind-tolerant shelter and shade tree. Crop: mulberries - abundant, blackberry-like fruit.
Pittosporum (Pittosporum spp.). Wind-tolerant, evergreen, hedge-forming, NZ native.
Stone pine (Pinus pinea). Slow growing, eventually very tall pine. Crop: pine nuts.
Sub-canopy small trees
Hazelnut (Corylus spp.). Prefers waterways. Wind-tolerant, deciduous. Wind-pollinated, usually dioecious. Crop: hazelnuts, late summer; production requires several trees of compatible cultivars.
Feijoa (Acca sellowiana). Wind-tolerant, evergreen. Bees: flowers mid-late summer. Crop: feijoas, late autumn; optimum fruiting requires 2-3 varieties.
Cherry Guava (Psidium cattleianum). Evergreen. May be invasive if unchecked by frosts (check with DoC). Crop: fragrant red fruit, like feijoa but smaller and more sour.
All the orchard fruit species - apples, pears, stonefruit. Sturdy heirloom species preferred for pest resistance, growth (increase yield with a co-planting guild - nitrofixers and mineral miners). Black Doris, Billington, greengage; Bramley's Seedling. Crabapple pollenators.
Woody shrub layer
Rocoto Chilli (Capsicum pubescens). 10-15 years, mildly frost tolerant. Chillies, mid-late autumn, black seeds. Very hot, thick fleshy skins.[1]
Cedrón/Lemon Verbena (Aloysia citrodora). 15+ years, mildly frost tolerant. Flowering bee plant. Crop: leaves and shoots as tea, dried or fresh.
Chilean Guava (Ugni molinae). 1-2m tall, evergreen, small glossy leaves. Crop: small red cranberry-like guava fruits, autumn.
Tree Tomato/Tamarillo (Solanum betaceum). More a small tree, 1.5 - 2m. Short-lived, 4-8 years. Hardy, salt tolerant. Crop: fruit, tree tomatoes. Orange variety is sweeter.
Redcurrant (Ribes rubrum), Blackcurrant (R. nigrum). Deciduous shrubs 1 - 1.5m. Full sun. Crop: berries. Requires bird netting to get any decent harvest.
Climbers
Scarlet Runner Beans (Phaseolus coccineus). Perennial, 10+ years. Dies off each winter and re-sprouts from root tuber. Fixes nitrogen. Bees: all summer. Crop: runner beans.
Passionfruit (Passiflora edulis). Short-lived, fast growing, requires at least partial sun, relative shelter. Not drought-tolerant.
Kiwiberry/Hardy Kiwi (Actinidia arguta). Very hardy, wind-tolerant, fast growing. Crop: bunches of small 3-4cm smooth-skinned kiwifruit.
Banksia Rose - thornless, old-fashioned rambler. Fast-growing, wind-tolerant. Bees: abundant yellow flowers late spring - early summer. Crop: rose-hips high in vitamin C.
Grape (Vitis vinifera). Wind-tolerant, hardy, deciduous. Muscat grows well in Wellington/Kapiti.
Herbaceous crops
Rhubarb, culinary herbs, perennial leek, Welsh onion, three-cornered leek, Good King Henry, Kale, perpetual spinach, Turkish rocket, chicory, loveage, mallow, ... most of the things in ch. 15 of the "Creating A Forest Garden" book, that aren't invasive in New Zealand.[2]
Ground Cover
Peppermint. Less vigorous, slower-growing, less invasive than common mint. Bees: all summer and autumn. Crop: peppermint leaves. Somewhat trample-tolerant.
Nasturtium. Dominant but easily controlled. It's about the only thing that can out-compete bindweed (Convolvulus spp.). Fixes nitrogen. Bees: flowers spring through autumn. Crop: peppery leaves, flowers.
Thyme.
Strawberries. Not trample-tolerant but can provide cover on litter and suppress other weeds. Will spread by vegetative propagation in autumn, but easily shifted.
Nepalese raspberry, orangeberry (Rubus spp.). Slow-growing, thornless, non-invasive bramble species. Crop: small raspberries. Trample-tolerant.
Root species
Yam/Oca (Oxalis tuberosa). Root crop.
Jerusalem artichoke (Helianthus tuberosus). Root crop. Tall sunflower relative, 1.5 - 2.5m. Flatulent.
Comfrey. Mineral accumulator. Taproot up to 4m long mines zinc, magnesium, iron etc. from subsoil into leaves; crop & drop mulch. Plant around fruit tree drip line. Choose location carefully; difficult to exterminate.
Chicory. Mineral accumulator. Crop: bitter leaves, root can be dug up and roasted.
