Allium senescens (German Garlic)
German Garlic, Mountain Garlic, Ornamental Onion
Allium senescens (German Garlic) is a bulbous herbaceous perennial that forms a tuft of twisted, grassy-looking, green leaves and produces up to 30 fragrant round balls of soft pink-lilac flowers atop upright stems in mid to late summer. Lasting for several weeks, they attract butterflies and hummingbirds. Suitable for rock gardens, atop retaining walls, these charming blossoms look equally terrific in perennial borders.
- Recipient of the Award of Garden Merit of the Royal Horticultural Society.
- Grows up to 6-12 in. tall and wide (30-60 cm).
- Thrives in fertile, well-drained soils in full sun to part shade. Best in full sun, but appreciates some afternoon shade in hot summer climates. This Allium is drought tolerant.
- Lovely in beds and borders, city gardens, cottage gardens, rock gardens, and containers. To achieve an impressive visual effect, plant in clusters.
- Known for attracting bees, butterflies, moths, and other pollinators, but deer ignore it.
- No serious pest or disease issues. Keep an eye out for slugs and snails, onion white rot, and downy mildew.
- Remove spent flowers to prevent the appearance of volunteer seedlings.
- Propagate by seed or by division during spring or autumn.
- Allium senescens is native to Europe, and northern Asia.
