In the garden

Allium 'Judith' is a cultivated ornamental within the genus Allium (family Amaryllidaceae), valued for its seasonal display of flowerheads from May to July. The blooms sit atop leafless stems while the basal leaves are deciduous, ripening away after the flowering period. Plant bulbs where they receive full sun and in soils that drain freely; this cultivar accepts chalk, clay, loam or sand and a broad pH range (acid to alkaline) provided moisture does not remain trapped. It suits south-, west- or east-facing positions and will tolerate both exposed and sheltered sites; H6 on the hardiness scale means it is very hardy for UK conditions. Allow the foliage to die down naturally so the bulb can replenish its reserves for the next season. Allium 'Judith' works well in flower borders and beds, gravel and courtyard gardens, patios and containers, and is also appropriate for wildlife-friendly planting and cut flowers. Because the blooms are carried on leafless stems, they are easy to harvest; if using them as cut flowers, cut when the umbels are just opening to maximise vase life.
