Purple Sensation Allium Bulbs
Purple Sensation Allium brings bold color and dramatic structure to the late spring and early summer garden. Each globe-shaped bloom is made up of hundreds of tiny purple flowers, perched high on tall, sturdy stems. Whether in garden beds, borders, or containers, these alliums make a striking statement and even double as standout cut flowers for arrangements.
Highlights
- Tall and Elegant: Stems can reach up to 3 feet, adding height and movement to garden designs.
- Late Spring Blooms: Flowers appear in early summer, bridging the gap between spring bulbs and summer perennials.
- Low Maintenance: Plant in fall and enjoy reliable blooms year after year.
- Wildlife Resistant: Deer and rabbits leave them alone, but pollinators flock to the blossoms.
- Cut Flower Favorite: Adds modern texture and long-lasting beauty to fresh or dried arrangements.
Planting Guide
- When to Plant: Best planted in fall before the ground freezes.
- Sunlight: Prefers full sun (6–8 hours daily) but can handle light shade.
- Soil Needs: Loose, well-draining soil enriched with compost or organic matter.
- Depth & Spacing: Set bulbs 4–6 inches deep and 4–6 inches apart.
- Watering: Water well after planting to settle the soil around the bulbs.
Ongoing Care
- Watering: Keep soil evenly moist during growth, watering deeply once or twice a week.
- Mulch: Add a 2–3 inch layer to conserve moisture and discourage weeds.
- After Flowering: Leave the foliage until it yellows naturally to feed the bulb for next year.
Growing in Containers
- Pot Size: Use a container at least 12 inches wide and deep, with good drainage.
- Soil Mix: A high-quality, well-draining potting mix works best.
- Watering: Keep soil lightly moist, making sure excess water drains away.
FAQs
1. What makes Purple Sensation Allium unique?
The large, spherical blooms—each made of tiny purple stars—rise on strong stems up to 3 feet tall. They provide bold color and architectural form when most spring bulbs have finished.
2. When and how should I plant the bulbs?
Plant in fall, about 4–6 inches deep and spaced 4–6 inches apart, in a sunny, well-drained location. Once established, they return year after year with little effort.
3. Do they attract pollinators?
Yes, bees and butterflies are drawn to the flowers, making them a pollinator-friendly addition to the garden.
4. Can they grow in pots?
Absolutely. Choose a pot with good drainage and at least 12 inches of depth. With the right soil and care, they thrive on patios, balconies, or small-space gardens.
5. How do I use them as cut flowers?
Cut stems when about half the florets have opened for long-lasting arrangements. If left in the garden, the seed heads dry into sculptural accents that add interest well into summer.
