How to grow Alliums

Ornamental alliums are hardy to zone 4 and thrive in most soils, as long as the soil is well-drained. Alliums prefer sunlight and perform best when they can bask in it all day long. Plant alliums on a full sun to partial shade spot. Alliums multiply naturally, so alliums can be left untouched and grows back each year. Remember, there is only one time of year to plant alliums: in autumn. If planted in autumn, alliums have enough time to establish before the frost. Watch alliums grow from May to June.

Alliums are long-lasting perennials that have a long flowering period. To extend the flowering period, we advise planting different varieties of alliums in the border. Some alliums bloom from May, and others flower from August.
