Allium tripedale

Allium tripedale (syn. Nectaroscordum tripedale) is a close relative of Nectaroscordum siculum subsp. bulgaricum, from which it differs by a denser and even more decorative umbel of flowers, which will bear more and larger bell-shaped pink flowers. This spectacular flowering takes place in late spring or early summer, and remains decorative for several weeks. Still difficult to find in horticultural trade, this magnificent Caucasian species is however no more difficult to grow than an ornamental garlic. A sunny to semi-shaded exposure, and especially well-drained soil, are the keys to successfully growing this quite fantastic bulbous plant.

Allium tripedale belongs to the Amaryllidaceae family. This botanical species originates from Armenia and a vast area covering Iraq, Turkey, and northern Iran. The plant grows from a bulb and its alliaceous-scented foliage emerges from the ground in late winter. Flowering takes place in May-June. The inflorescence forms at the end of a solid and cylindrical stem measuring 90cm (35in) to 1.3m (4ft) in height, initially resembling a large bud covered with a papyraceous whitish envelope. The bud opens to release an umbel in the shape of an umbrella, sometimes irregular in shape, reaching about 10cm (4in) in diameter. This umbel is composed of 20 to 30 pendulous bell-shaped flowers, 2cm (1in) in diameter, which gradually open over a period of 5 to 6 weeks. The petals are iridescent, ranging from white to pale-pink, striped with fuchsia-pink. The flowers open to reveal their green throat adorned with stamens. They are nectariferous and highly sought after by bees and other pollinating insects. The foliage, arranged close to the ground, is composed of linear green leaves. It usually turns brown and dries out before flowering. The fruits are conical and brown, and are erect on pedicels. It produces very few daughter bulbs and mainly reproduces by sowing. The seedlings will flower after 6 years.

A superb, frost-resistant novelty for our gardens. It appreciates sunny to slightly shaded environments and well-drained soils that remain slightly moist throughout its growth and flowering period. A drier soil in summer is well tolerated. It is a fairly accommodating bulb that thrives on the edge of woodlands, in a bed, or rockery. It is best planted in groups of 5 for a beautiful effect, and pairs perfectly with late tulips in white, pink, red, or mauve. Foxgloves and penstemons will cover its absence in summer.
