protea-neriifolia-limelight

Protea neriifolia 'Limelight'

Evergreen shrub with lanceolate leaves, flowering mainly during autumn and winter with creamy-green flower-heads with purple-red tufts on the bracts. Similar to, but a smaller shrub with smaller flowers than 'Green Ice'

'Limelight' (= 'Green Jade') is a cultivar developed in 1950 in New Zealand, originating from the oleander-leaved or narrow-leaved Protea neriifolia, which is endemic to South Africa.

Prefers a sunny position in acidic, and relatively poor soil. Any soil type is suitable but it must be well-draining. A yearly application of blood and bone in spring is recommended, but otherwise keep the nutrient levels low and don't apply any further fertilisers. In general, proteas dislike humidity, so a relatively windy site is ideal, since the wind keeps the humidity down. Staking will be required in very windy locations. No additional watering is necessary, except maybe in extremely dry summers. Mulch to keep the weeds down or grow as a lawn specimen, to limit the need to remove weeds around the plant and thus disturb its sensitive, shallow root system. They can be pruned quite heavily, but not beyond the foliage. Remove dead and damaged wood, as well as the by-pass shoots that the develop just below the flower-head. Suitable for coastal conditions.

Striking plant when in flower. Perfect for coastal gardens. The flowers (and foliage) last for ages on water. Just be careful not to "kill them by kindness"!

prunus-billington

Prunus 'Billington'

plum Billington, Japanese plum Billington

Small deciduous tree with white blossoms in late winter and dark red plums in summer. Fruit has firm, sweet tasting, juicy, red flesh. Use as fresh fruit, or for cooking and preserving. Partially self-fertile. Pollinators: 'Black Doris', 'Wilson's Early', 'Omega' or 'Santa Rosa'. Sometimes available as part of a double-grafted plum tree.

Prefers a sunny position in fertile, well-draining soil. Good disease resistance.

Prunus 'Billington' is an early-fruiting plum with a heavy crop of fruits ripening around Christmas time in New Zealand. Beautiful dainty appearance when in flower during winter. Good 'all-rounder'.

prunus-awanui

Prunus x yedoensis 'Awanui'

Vigorous, ornamental cherry, flowering in spring with masses of slightly fragrant, pale pink-white, single flowers. Foliage turns yellow and orange in autumn. 'Awanui' (and Prunus x yedoensis itself), is propagated by means of grafting, but also roots easily from cuttings. Usually it is top-worked, i.e. grafted at a higher level as opposed to near ground-level) to form a clear-stemmed tree with layered branches. Attracts birds, bees, and butterflies.

'Awanui' is a cultivar of the Japanese Prunus x yedoensis, also known as the Yoshino cherry. It was selected by the New Zealand nurseryman Keith Adams. 'Awanui' was the name of the street that gave access to his property, and is the Maori world for gully.

Prefers a sunny position in any well-draining soil. Provide some shelter to prevent flower damage and prolong flowering. Good disease resistance. Frost hardy (zones 5-9). 

An avenue with a row of flowering Prunus x yedoensis 'Awanui' on either side is breathtakingly beautiful. Make sure you have sufficient space for this gorgeous tree as it gets quite wide.

pseudopanax-cyril-watson

Pseudopanax 'Cyril Watson'

Pseudopanax lessonii hybrid in the Araliaceae family, named after Cyril Watson, a sales manager at Duncan and Davies nursery in New Plymouth, New Zealand, who was instrumental in the development and release of this plant. Bushy, slow-growing, evergreen shrub with lush, green foliage. Leaves are leathery and have 3 to 5 rounded, partially fused lobes with toothed margins. Inconspicuous, greenish flowers in summer.

Prefers a sunny or partially shaded position in any well-draining soil. Seems to cope with full shade quite well also. Tolerates moderate frosts once established, but may require frost protection when young. Trim yearly, or prune relatively hard every couple of years to keep compact and maintain a good shape.

Attractive fresh green foliage plant, perfect as a filler or backdrop for other plants. Suitable for containers.

pseudopanax-linearifolius

Pseudopanax 'Linearifolius'

Erect growing evergreen New Zealand native shrub, probably a hybrid of Pseudopanax crassifolius and Pseudopanax lessonii. Leathery leaves with three to five (3-5 foliolate) long, narrow leaflets with serrated margins. Leaves may become 3-foliolate or even simple (i.e. a single leaf per node) as the plant matures.

Requires well-draining soil and is not tolerant of damp soil conditions. Grows well in any light situation from shade to full sun. Tolerates light to moderate frosts, coastal conditions, dry shade, and exposed sites.

Ideal tub plant. Great as a backdrop for smaller plants and useful as a contrast plant in particular when combined with large-leafed shrubs such as Griselinia lucida or Meryta sinclairii.

psoralea-pinnata

Psoralea pinnata

Dally pine, blue Psoralea, African scurf pea, blue pea, fountain bush, blue broom, taylorina, fonteinbos, penwortel

Evergreen shrub or small tree in the legume family, with bright green, soft, needle-like leaves. Flowering in early spring with blue and white or lilac and white, pea-like, bee-attracting, scented flowers (to 1.5 cm across) clustered at the ends of the branches. The flowers are followed by small, wrinkled seedpods that each contain a seed. Psoralea pinnata is native to South Africa where it occurs naturally along streams and wet places (i.e. winter-wet areas). It has established itself in other regions of the world such as Southern Australia and the north of New Zealand where it is regarded as a weed. Psoralea pinnata tolerates a wide range of growing conditions, including wind, drought, high rainfall, coastal conditions, and poor soils. Because it is a nitrogen-fixer, it changes the growing environment for the original native plant species that may no longer be able to compete as a result. Germination is stimulated by fire. The pant is relatively short-lived (about 10 years).

Psoralea pinnata prefers a sunny position, except in areas with very high summer temperatures where a partially shaded site is better. Tolerates waterlogged soils, but also copes with occasional drought once estabished. Prune after flowering. Self-seeds quite easily. Tolerates light to moderate frosts (zones 9-11).

Striking tree when in flower. You may need to give it some help in the form of pruning and training to develop a good shape as it does not appear to do so naturally and often has a somewhat straggly, unbalanced appearance.

pyrus-salicifolia-pendula

Pyrus salicifolia 'Pendula'

weeping silver pear or willow-leafed pear

Graceful small tree with a rounded canopy, silvery grey willow-like foliage and pendulous branches. Creamy white flowers, to 2 cm across, in spring, some of which are followed by small pear-like, inedible fruit in autumn. Brief period of yellow autumn foliage. 'Salix' is the Latin word for 'willow'.

Prefers a position in full sun or partial shade in well-drained soil. Adaptable to a range of soil conditions. Suitable for coastal planting. Prune in late autumn to keep the canopy compact. Remove branches below the canopy to make sure the rootstock is not going to overtake, and to keep a 'clean' stem.
