💜 Giant Allium – The Showstopper of Your Garden

Imagine a late-spring morning: giant purple globes float above your flower beds like fireworks frozen in bloom. Bees hum from flower to flower, and every neighbor who walks by stops to ask, “What is that?!” ✨

🌟 Thousands of Tiny Stars in One Bloom

Each flower head is made of 2,000–3,000 tiny star-shaped florets that come together into one perfect, eye-catching sphere, set above soft gray-green leaves.

🌸 Big Blooms, Long Show

The globe grows larger as the florets open, reaching up to 8 inches (20 cm) across. Each bloom lasts nearly 20 days, giving you weeks of dramatic color.

❄️ Cold-Tolerant & Easy to Grow

Giant Alliums handle cold down to about 5°F (-15°C). In most areas they can stay in the ground through winter; in very cold regions, add a thick layer of mulch or overwinter bulbs indoors.

🌱 Feeding Tips

Mix slow-release fertilizer into the soil at planting, or add some in spring once shoots appear
During the bud stage, feed with a bloom-boosting fertilizer about every 10 days
After flowering, add a little slow-release fertilizer and let the leaves yellow naturally so the bulb can store energy for next year

💐 After the Blooms

Flowers appear in late spring to early summer and begin to fade around June, when the florets turn into small green seed heads. Cut the stems midway to enjoy them as fresh arrangements or dried flowers, bringing the beauty indoors for months.
