Airy rosy-flowered garlic for naturalizing
Rosy-flowered garlic
Allium roseum
Product code : VAN-146-188-01
Allium roseum, or rosy-flowered garlic, produces delicate pale-pink umbels at 35 cm (14 in) above fine foliage. The Van Noort package contains 20 pink Allium bulbs size 5/6 for rock gardens, borders, and containers. Summer dormancy should remain comparatively dry, especially in heavy soil or containers. Pink flowers provide pollen and nectar for bees, bumblebees, butterflies, and other beneficial insects. Some heads may produce bulbils; remove them to limit spreading or retain them for naturalizing. Deer usually avoid onion-scented tissues, but the plant remains toxic to pets. An irregular group looks more natural than a row and creates a pink haze above fine foliage. This naturalizing pink Allium is also a pollinator friendly Allium for compact sunny plantings.

Botanical nameAllium roseum
Rosy-flowered garlic (Allium roseum) creates a lighter display than classic globe-shaped ornamental onions. Slender 35 cm (14 in) stems carry loose umbels in which pale-pink cup-shaped flowers seem to float separately. Narrow, flexible, mid-green foliage resembles a small grass and disappears after feeding the bulbs. Some flower heads may produce bulbils, offering a route toward gradual naturalizing. Pink flowers provide pollen and nectar for bees, bumblebees, butterflies, and other beneficial insects. Some heads may produce bulbils; remove them to limit spreading or retain them for naturalizing. Deer usually avoid onion-scented tissues, but the plant remains toxic to pets.
Plant the twenty size 5/6 bulbs in fall, pointed end upward, 8 cm (3 in) deep and 10 cm (4 in) apart. Distribute them in small irregular drifts within a warm, sunny position. In Canada, Zones 6 to 9 hardiness calls for a protected microclimate or carefully overwintered container culture in colder regions. Loose, sharply drained soil protects the small bulbs from excessive winter moisture. Water after planting, then only when the soil surface dries during active growth. A light application of mature compost in spring generally supports flowering sufficiently. Let every leaf yellow naturally so bulbs can rebuild the reserves required for another season.
Allium roseum softens rock gardens, borders, gravel plantings, and containers with a late-spring pink haze. Pair it with thyme, lavender, catmint, compact salvias, and fine grasses. Flowers support pollinators and enter cottage-style bouquets. Monitor bulbils so you can choose between an expanding colony and a strictly controlled planting. Some heads may produce bulbils; remove them to limit spreading or retain them for naturalizing. Deer usually avoid onion-scented tissues, but the plant remains toxic to pets. An irregular group looks more natural than a row and creates a pink haze above fine foliage.

Growing method
Plant the bulbs in fall within a warm, sunny position. Loosen soil to 20 to 25 cm, incorporate a little mature compost, and broadly improve heavy ground with fine grit. Set every size 5/6 bulb point upward 8 cm deep and 10 cm from the next. Divide twenty bulbs among three or four drifts, cover, firm gently, and water deeply once. Mark every group precisely. Full sun keeps slender stems upright and able to support loose umbels without staking. Loose, sharply drained soil protects the small bulbs from excessive winter moisture. Water after planting, then only when the soil surface dries during active growth. A light application of mature compost in spring generally supports flowering sufficiently.

Summer dormancy should remain comparatively dry, especially in heavy soil or containers. Pink flowers provide pollen and nectar for bees, bumblebees, butterflies, and other beneficial insects.
Moisture
Lightly moist spring soil, sharply drained, and dry through dormancy
Seasonal care
In fall, plant, label, and lightly protect the drifts after soil cools. In late winter, verify drainage and remove compacted debris. During spring, hand-weed around fine shoots and water only if soil dries. During bloom, avoid insecticides and decide which heads may develop bulbils. After flowering, cut no green leaf. Once foliage is fully yellow, clean at soil level and sharply reduce water. In cold zones, protect pots and microclimates before severe freezes. Mark every position because the foliage disappears completely when plants enter dormancy. In colder Canadian regions, grow bulbs in protected pots or select a warm microclimate. Airy umbels suit small cottage-style bouquets and dry while retaining a delicate silhouette. Inspect drainage after thaws and promptly correct every place where standing water remains. Divide groups only when they become crowded or flowering begins to decline. Avoid high-nitrogen fertilizers that encourage soft foliage at the expense of flowers.

Recommended pot size
At least 25 cm (10 in) deep and 30 cm (12 in) wide
Use a frost-resistant container at least 25 cm deep and 30 cm wide with several large holes. Fill it with light potting mix enriched with compost and mineral material. Plant bulbs 8 cm deep, water once, and place the pot in sun. In regions colder than Zone 6, insulate the walls, temporarily sink the container, or overwinter it in a cold position protected from extreme freezes. Do not move it into a heated room. Catmint, thyme, lavender, compact salvias, and grasses share its preference for sunny positions. Mineral mulch limits weeds without trapping excessive moisture around the bulbs.
