'Serendipity' Ornamental Onion (Allium) boasts globe-like, rosy-purple flowers mid to late summer that top attractive blue foliage. The upright habit works as a thriller in containers and the landscape. Alliums are charming plants for the rock or herb garden. When the foliage is bruised, it smells like onions since they are in the onion family. Butterflies and honeybees adore the flowers' sweet nectar but deer and rabbits steer clear of this perennial beauty.

Beautiful root balls and well packaged

I ordered these allium in early fall when the blooms were already gone, but the foliage looks very healthy, the root ball is nicely developed, and the shipping was packaged well. Can’t wait for next year to see the blooms!

Great service and selection

Had been searching for these locally all summer. Just discovered PWD and am very happy. Plants were in good shape and expertly packaged. End of the season for us here in Michigan, but they will get a hold for next year.

Serendipity Allium

This allium is beautiful. I love the size; its perfect for the space where I planted it. The plants were so healthy when they arrived, and they have gone into the ground and never slowed down. I look forward to enjoying them for years to come.
