With its often purple and ball-shaped flowers, the ornamental onion visually compensates for weak points in the garden. But he doesn't feel like he's in good hands at every location.
Which location is optimal for ornamental onions?
The ideal location for ornamental garlic is a sunny to partially shaded place with nutrient-rich, humus-rich, moderately moist to dry, well-drained and calcareous soil. However, some varieties, such as Allium triquetrum, prefer partial shade to shade.
A lot to little sunshine
The ornamental onion prefers to be in full sun. It can also thrive in partial shade without any problems. But there are also varieties that prefer to be in partial shade to shade. This includes, for example, Allium triquetrum. Basically, almost all types of ornamental onions are warm-loving.
The substrate: nutrient-rich and permeable
You should plant your ornamental onion in a substrate that mimics the soil of its area of origin. The following properties are extremely advantageous:
- nutrient-rich
- humos
- moderately moist to dry (the larger the onion, the drier)
- well drained
- calcareous
Tip
Since the ornamental onion has unsightly yellowish foliage in summer, it should be planted with ground-covering and clumpy perennials such as lady's mantle, cranesbill and floribunda.
