A native of South Africa, summer hyacinth sends up spikes of lovely white flowers in late summer amidst dark green, strap-like foliage, when many other perennials are done blooming. The tall spikes are fragrant and especially dramatic planted with darker foliage or flowers.
Noteworthy CharacteristicsFragrant, bell-shaped white flowers, tinged with green, and strap-like foliage make this plant welcome in the late summer garden.
CareFertile, well-drained soil that is reliably moist in spring and summer. Full sun. Overwinter in a cool greenhouse or mulch deeply in areas with harsh winters.
PropagationSow seed in containers in a cold frame as soon as ripe, keeping the seedlings frost-free for the first 2 years. Offsets can be removed in spring.
ProblemsInfrequent, but sometimes slugs and snails.
