nandina-domestica-richmond

Nandina domestica 'Richmond'

Evergreen shrub with finely divided leaves and showy brilliant red berries in winter. Stems are upright and cane-like, a bit like bamboo (but not suckering), hence the common names "heavenly bamboo", "Chinese bamboo" and "sacred bamboo" for the species. Foliaged is composed of many small lance-shaped to elliptical leaves to 2 cm long, some of which colour up to burgundy-red in the colder months of the year. Small creamy white, star-shaped flowers, 1 cm across, in panicles at the ends of stems mainly during summer.

Nandina domestica 'Richmond' is self-fertile, i.e. does not require another plant to produce berries. For Nandina domestica itself to  form berries both male and female plants should be planted together.

Prefers a partially shaded or sunny position in any, fertile soil. Copes reasonably well with  full shade. Quite drought-tolerant. If pruning is required, selectively prune some of the stems at a ttime instead of cutting the whole plant back.

Its growth habit and delicate foliage make this the perfect choice for gardens with an oriental theme. Can also be grown as a tub plant.

nerine-sarniensis

Nerine sarniensis

Guernsey lily, Jersey lily, red nerine, berglelie

Perennial bulb, native to South Africa, with strap-shaped leaves and umbels of up to 20 lily-like flowers. The plant is dormant during summer, sending up flower stems in early autumn, with new leaves emerging soon afterwards. The leaves are rather like those of Agapanthus. The bright reddish orange flowers are funnel-shaped with recurved petals and protruding stamens. Breeding has led to several hybrids and cultivars with flower colours ranging from white to pink, red, and purple.

It is not clear how bulbs of this South African plant ended up on the island of Guernsey more than 300 years ago, but they continue to be grown there for cut flower production.

Nerine sarniensis prefers well-draining soil and full sun or a position where it receives sunlight for at least half of the day. Plant with the top part of the bulb (neck) exposed. Keep dry during summer, but, depending on the amount of rain fall, regular watering may be required during the growing season. Careful with fertilising, in particular with fertilsers high in nitrogen; this may encourage leaf-growth at the expense of flower production. Flowering can be erratic and fluctuating from year to year, possibly due to variations in environmental conditions.Tolerates brief periods of moderate frosts. Propagate by division, detaching the new bulbs that form around the main bulb, and replanting them straight away.

Allow this beauty to be the star of early autumn and combine with plants that take over that role at other times of the year. Flowers last well on water. If you live in an area with cold winters, you can still enjoy Nerine sarniensis by growing the plant in a container and moving it indoors to overwinter in a well-lit place with good ventilation.

nerium-oleander

Nerium oleander

Oleander

Evergreen shrub or small (usually multi-stemmed) tree, flowering in summer with 2.5-5 cm wide, white, pink, or reddish pink flowers in clusters at the end of the branches. Dark green, lanceolate to linear leaves, 5-20 cm long, 1 to 3 cm wide, arranged in twos or threes. Flowers may be, but are not always, scented. All parts of the plant are poisonous. Indigestion can be fatal. Contact with the flowers or foliage may cause severe allergic reactions, so wear long sleeves and gloves when handling Nerium oleander. Its native region stretches from the Mediterranean area to India and Southern China.

The common name alludes to its resemblance to the olive, Olea. Nerium oleander is the official flower of Hiroshima, being the first to flower after the atomic bombing of the city.

Easy to grow in just about any soil. Requires very little maintenance. Prefers a sunny position, but copes with partial shade. Established plants generally don't require fertilisation. Prune for shape in autumn. Can be pruned quite hard. Avoid touching the milky latex that exudes from the cut stems. Tolerates drought, coastal conditions, and moderate frosts (zones 8-11). Suitable for exposed sites, although strong winds may damage flower buds and open flowers. Yellowing of the leaves is usually a sign that the soil is too wet.

A magnificent sight when the plant is completely covered with flowers in summer. There are many cultivars available, with single or double flowers, and in a range of colours. In cold climates, Nerium oleander can be grown in a container and brought indoors for the winter.
