'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.

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.

So happy!

I love the serendipity allium because they are late summer and keep their nice green leaves unlike most allium. They came right away and perfectly packaged so there was no damage. The plants came out of the boxes nursery-fresh!
