Extend the allium season with this late-summer delight, Allium angulosum 'Summer Beauty'. If ever you wished you could enjoy the bobbing purple blooms of alliums beyond late spring or early summer, this is one to snap up immediately! Displaying all the wonderful allium characteristics, including nectar-rich globe blooms which are total bee magnets, long, upright stems which provide a chilled-out movement in the border, and a pleasant cool-mauve hue – plant groups of Allium 'Summer Beauty' and you’ll find there’s a whole lot of allium joy to look forward to from mid summer right through to early autumn!
These easy-to-grow and fully hardy perennial alliums grow from bare roots rather than bulbs, and happily establish over the years to produce a strong and impressive chunky group. Run swathes of them through the border or a few focal-point groups, alternatively, give them a sturdy pot on the patio. If you enjoy cutting flowers from the garden to display indoors, you’ll love having an established group of these beauties for fresh snippings through the summer months!

Plant profile
Plant calendar
Choose full sun or partial shade. Improve heavy soil with organic matter and horticultural grit. For containers, use peat-free multipurpose compost with good drainage.
Plant bulbs pointed side upwards, two to three times their own height deep. A slightly flattened side is perfectly normal and nothing to worry about.
Space small bulbs around 5cm apart. Larger bulbs need more room, generally around twice their own width apart, so their foliage and flowers can develop freely.
Water after planting if the soil is dry, then only when needed. After flowering, allow the foliage to die back naturally. Decorative seedheads can remain in place.
