Bulb

amaryllis-belladonna

Amaryllis belladonna

naked lady, belladonna lily, March lily

Clump-forming bulbous plant, native to South Africa. Long, strap-like, mid green leaves to about 50 cm long. Foliage emerges in autumn and dies back in late spring. Mildly scented, 10 cm long, trumpet-shaped, pink flowers appear in late summer in heads of 2-12 on 30-60 cm long purplish red stems. The common name 'naked lady' refers to the fact that the plant flowers while the foliage is dormant. Amaryllis belladonna is poisonous, and the sap and bulbs may cause skin irritations.

Prefers a sunny or partially shaded position in almost any well-draining soil. Tolerates considerable dryness, in particular when the foliage has died back. Leaves can handle quite a bit of wind, but flower stems get damaged by strong winds, so a sheltered spot where the flower stems don't get blown about, is best for a good display. Amaryllis belladonna likes to be left undisturbed, but clumps of bulbs can be divided. Individual bulbs should be planted with their necks at or just above (not below) soil level. Tolerates moderate frosts to about -80 C.

Amaryllis belladonna is easy to grow and reliably produces a magnificent display of flowers from late summer onwards. Suitable for rock gardens, containers, under large deciduous trees, coastal gardens and borders. Flowers last well on water.

amaryllis-belladonna-alba

Amaryllis belladonna 'Alba'

white naked lady, white belladonna lily

White-flowering cultivar of a South African, bulbous, clump-forming plant with long strappy leaves to 50 cm long. Foliage emerges in autumn and dies back in late spring. Large, 10 cm long, trumpet shaped, mildly scented flowers appear in late summer in heads of 2-12 on 30-60 cm long, leafless, purplish red stems. Amaryllis belladonna is poisonous, and its sap and bulbs may cause skin irritations. The common name 'naked lady' for Amaryllis belladonna refers to the fact that the plant flowers while the leaves are dormant.

Prefers a sunny or partially shaded position in almost any well-draining soil type. Tolerates considerable dryness, in particular when the foliage has died back. Leaves can handle quite a bit of wind, but flower stems get damaged by strong winds, so a sheltered position where the flowering stems don't get blown about, is best for a good display. Plants like to be left undisturbed, but clumps of bulbs can be divided and individual bulbs should be planted with their necks at or just above soil level (not below).  Tolerates moderate frosts to about -80C. 

Suitable for flower display in rock gardens, arge containers, under large deciduous trees, coastal gardens and borders. Flowers last well on water.

colchicum-autumnale

Colchicum autumnale

Autumn crocus, naked ladies, meadow saffron

Herbaceous perennial with narrow strap-shaped leaves, flowering in autumn with lilac crocus-like flowers (5-8 cm wide). The leaves appear in spring and die down before the flowers emerge. All parts are poisonous on ingestion and contact with the skin may cause irritations.

Originally from Central and South-East Europe, Colchicum autumnale is naturalised in many countries, including New Zealand. Although the flowers look very similar to those of the Crocus, Colchicum autumnale and Crocus belong to different plant families and are only distantly related in a genetic sense. Apart from a difference in flowering time, you can also tell them apart by the fact that a crocus has three stamens and an autumn crocus has six.

Prefers a sunny, sheltered position in well-draining soil. Poor drainage may result in corm rot. In hot climates, partial shade is best. Can be propagated by dividing the corms when they are dormant during winter. Frost hardy (zones 5-9).

Lovely for flower display in woodland gardens or in containers. When selecting a spot, consider the fact that the leaves will turn yellow and die in summer, so you may not wish to give it the prime position in your garden, but one to give you a sweet surprise when walking past in autumn. The flower stems tend to be somewhat floppy, and possibly surrounding ground-covering plants could offer support. 

crocosmia-crocosmiiflora

Crocosmia x crocosmiiflora

Montbretia

Perennial in the Iris family with light green, long and narrow leaves (90 x 2 cm) that spreads with underground rhizomes. Sprays of bright orange flowers held on long, thin, zig-zag stems, arising from the foliage clumps during late summer. Can become invasive in mild, wet climates as it tolerates many adverse conditions including grazing. The seeds are not a problem, since not many are produced, but the plants can multiply and spread rapidly via their corms and rhizomes. In New Zealand and some other parts of the world Crocosmia x crocosmiiflora is regarded as an environmental weed, competing with ground covering shrubs and native seedlings.

Crocosmia x crocosmiiflora is a hybrid bred in France in 1880 by crossing two African species Crocosmia aurea and Crocosmia pottsii.

Prefers a sunny, sheltered spot in well-draining soil, but will adapt to most soils and tolerates partial shade, heat, and moist soils. Quite drought tolerant, but benefits from an occasional watering during exceptionally dry weather. Frost hardy (zones 5-9). In cold climates, the corms can be lifted and stored in a cool, dry place until spring. 

Easy to grow and consistently produces lots of flowers. Divide the clump after a few years to maintain vigour. Suitable for containers and cut flowers. Beautiful bright colours.

eucomis-reuben

Eucomis comosa

pineapple lily

Originally from South Africa, Eucomis comosa is a winter-dormant bulbous plant with a basal rosette of strap-shaped fleshy, bright green leaves with maroon spots. The cream, waxy flowers are arranged in tight spikes with a tuft of green bracts at the top. There are several hybrids, such as 'Sparkling Burgundy' which emerges in spring with burgundy-red foliage, changes to green later and reverts back once the flowers fade. Its flowers are dark pink and the spikes have a tuft of purple bracts at the top. The photograph that shows hydrangeas in the background is of Eucomis comosa 'Reuben', bred by New Zealand grower Eddie Welsh.

Synonym: Eucomis punctata

Prefers a sunny position in any well-draining soil that is relatively dry in winter and moist in summer. Tolerates partial shade, but the best flower and foliage colours are produced in full sun. Suitable for USDA zone 8, but in areas where heavy frosts may occur, Eucomis comosa is best grown in a container and moved to a frost-free location during winter. Bulbs can also be lifted each autumn, stored in a dry medium, such as peat, and planted out again in spring. Easy to divide, but smaller bulbs may not flower in the first year after division. 

Beautiful plant, in particular the pink-flowering varieties. As cut flowers they last for many weeks.

muscari-armeniacum

Muscari armeniacum

grape hyacinth, Armenian grape hyacinth

Small, perennial, early spring-flowering bulb to about 20 cm tall. Slightly fragrant blue, purple or white flowers in dense 5 cm long spikes, resembling clusters of upside-down grapes. Narrow, linear leaves appear in autumn and die down in summer after which they can be removed. Reproduces by offsets from the main bulb and seed dispersal.

Occurs naturally in forests and meadows of Eastern Mediterranean regions.

Prefers full sun or partial shade and well drained soil. Generally trouble-free, but susceptible to root rot in wet sites. Divide large clumps in summer.

Looks great when planted in groups.

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.

scilla-peruviana

Scilla peruviana

giant scilla, Peruvian lily, Cubian lily, Carribean lily, Portuguese squill, hyacinth of Peru, star of Peru

Bulbous plant with basal, linear leaves (20-60cm long and 2-4cm wide) flowering during spring with starry blue, 1.5 cm wide flowers arranged in dense racemes. Foliage dies down after flowering and a brief dormant period follows in summer. Is naturalised and regarded as a weed in some parts of Australia.

Although 'peruviana' means 'from Peru', Scilla peruviana originates from South-West Europe to North-West Africa. Bulbs collected in 17th century Spain were shipped to England on a ship named 'Peru'. Carolus Clusius named the plant Hyacynthus stellatus peruanus, thinking that it came from Peru. Linnaeus continued the confusion by renaming the plant Scilla peruviana.

Scilla peruviana is still the most widely used name, but this species has been renamed Oncostema peruviana.

Prefers a sunny or lightly shaded spot in well-draining soil. Drought tolerant once established. Best planted during the dormant period in summer with the neck of the bulb just above soil level. Can be lifted, divided, and replanted, but may not produce flowers until after a year or two. Suitable for coastal gardens. Tolerates moderate frosts (zones 8-10).

Stunning spring colour. In areas where heavy frosts occur, Scilla peruviana can be grown in containers and placed outside once the spring frosts are over.
