  • The plantalliums in the garden tend to look odd. Three to five spacing well apart for large alliums or a group of 10 to 15 for smaller species is the best way to get the best effect.
  • Alliums look great among mounding Perennials such as lady ‘s mantle, true geraniums, irises, or sedums. Hostas, silver-leaved artemesias, and peonies are good companions. The foliage of the alliums tends to get brown by the time they flower.

  • To support theblooms, stake taller varieties.
  • Feed with a liquidfertilizer in the early summer.
