{"title":"Giant allium","description":"\u003cp\u003eWant to add instant height and calm to your border in spring? In this giant allium collection, you'll find large ornamental alliums with round flower heads on sturdy stems. They are easy to combine with perennials and ornamental grasses and quickly create a striking yet calm look. Plant the bulbs from September to November for flowers in May and June. Want to compare sizes and heights? \u003ca href=\"https:\/\/blomgarden.nl\/collections\/allium\"\u003eExplore all alliums\u003c\/a\u003e.\u003c\/p\u003e\u003ch2\u003eWhy choose a giant ornamental allium?\u003c\/h2\u003e\n\u003cp\u003eGiant allium is loved for its strong shape. The flowers seem to float like round globes above the border and bring structure without making the planting look heavy. That makes this ornamental allium suitable for both a formal border and a more natural garden.\u003c\/p\u003e\n\u003cp\u003eBesides its ornamental value, giant allium is also a practical choice. The plant needs little attention, combines easily with other garden plants, and attracts bees and other pollinators. Even after flowering, the seed heads often stay decorative, so you can enjoy them for longer. Want to do more for pollinators? Discover our \u003ca href=\"https:\/\/blomgarden.nl\/collections\/inspiratie-bijvriendelijk\"\u003ebee-friendly flower bulbs\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch2\u003ePlanting giant allium\u003c\/h2\u003e\n\u003cp\u003eYou plant allium bulbs in autumn, from September to November. Choose a spot in sun or partial shade with well-drained soil. Giant ornamental allium is less suited to places where water sits for a long time in winter, so an open spot usually gives the best results. Planting in containers or on a balcony? See \u003ca href=\"https:\/\/blomgarden.nl\/collections\/allium-voor-potten\"\u003ealliums for pots\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eThe right planting depth and spacing vary by variety. So always follow the product information for the bulbs you choose. For a strong effect in the garden, it works well to plant giant allium in small groups or repeat it through the border. For step-by-step tips, see \u003ca href=\"https:\/\/blomgarden.nl\/pages\/allium-planten-en-verzorgen\"\u003eAllium planting and care\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch2\u003eCare and coming back each year\u003c\/h2\u003e\n\u003cp\u003eGiant allium is an easy garden bulb. Let the foliage die back naturally after flowering, so the bulb can store energy for the next flowering season. You can remove spent flower heads, but you can also leave them in place as decorative seed heads.\u003c\/p\u003e\n\u003cp\u003eMost giant alliums can stay in the ground and often return every year, as long as the spot is not too wet. In exposed places, a sheltered spot helps keep the tall stems upright. That combination of low maintenance and strong impact is exactly what makes giant allium so popular.\u003c\/p\u003e\n\u003ch2\u003eCombining well in the border\u003c\/h2\u003e\n\u003cp\u003eBecause of its round flower shape, giant allium combines well with plants that have fuller foliage or a looser habit. Think ornamental grasses, sage or lavender. This is not only attractive, but also practical, because surrounding plants can subtly hide the foliage later in the season.\u003c\/p\u003e\n\u003cp\u003ePrefer a softer palette?

It is an autumn-planted bulb that you plant in autumn for flowers in May and June.\u003c\/p\u003e\n\u003ch3\u003eDo alliums come back every year?\u003c\/h3\u003e\n\u003cp\u003eMany alliums come back every year if they are in a suitable spot. Well-drained soil in particular helps keep the bulb healthy. Always let the foliage die back first after flowering before removing it.\u003c\/p\u003e\n\u003ch3\u003eDoes allium self-seed?\u003c\/h3\u003e\n\u003cp\u003eSome alliums can self-seed, but this varies by variety and location. For reliable results, mainly count on the bulb itself coming back, not just on spontaneous self-seeding.\u003c\/p\u003e\n\u003ch3\u003eIs allium winter hardy?\u003c\/h3\u003e\n\u003cp\u003eGiant allium is usually grown as a hardy bulb and can generally stay in the ground.
