Description

(Ornamental Onion) It’s always fun when a ‘sport’ is found and that is the case with Allium ‘Serendipity’. A blue foliage allium was found mixed in with Allium ‘Millenium’ a green foliage form, this resulted in an unexpected occurrence or “serendipity”. With all the great attributes that ‘Millenium’ boasts, ‘Serendipity’ features loads of 1.5-2 inch purple globe-shaped flowers on a 15-20 inch tall mounding blue-green clump. Mid to late-summer the flowers appear bringing with them the hum of pollinators and butterflies. The fragrant foliage smells like onions when crushed. Hardy in zones 4-8, allium likes to be grown in full sun to part sun locations and is drought tolerant once established. Easy to grow and makes a nice cut flower, ‘Serendipity’ is a perfect selection for mass plantings as well as a garden border. Allium ‘Serendipity’ is a Proven Winners® Perennial.

Serendipity Allium

I garden in Kansas (6B), I ordered six quarts of “Serendipity” Alliums for my garden this year. I have never grown Allium but I wanted this plant for my honey bees. I have to say, I love the foliage on this plant, it has not bloomed since it was planted in May. The foliage without the blooms is a very striking with its upright and perky foliage that compliments my rock borders, so I would say it has interest even without experiencing the blooms as of yet but can’t wait for the show. I can not say enough regarding all of the plants I have ordered from Garden Crossings, my plants were packed with care, attention to detail is above my expectations which is why I will only order on-line from Garden Crossings when it comes to receiving quality plants. I do have to comment, I have reached out to change my order after I submitted my pre-order for my plants and the customer service has been the best experience, Heidi changed my order with a smile through email correspondence and without any errors when I received my shipment. I am a person that reads reviews and it will determine my decision if I will spend my money with their company. Quality and customer service is very important to anyone who loves plants. I am not only addicted to plants but developed an addiction to ordering from Garden Crossings too!!!

Serendipity Allium

The plants arrived in beautiful condition. It's been a month since I planted them -- they look very healthy and are ready to explode with blooms.

The alliums are taking root. Came looking really good. Note: We’re in Tallahassee, FL and had tornados here last week. Lots of trees on top of houses and in yards, power outages, roads blocked and some washed out in rural areas. We had half of our PW showstopper salvias flattened and our cleome senoritas rosalita from your nursery, too. Replanted them & staked. They seem to be recovering.
