A classic ornamental onion. Allium christophii has a large lilac flowerhead, measuring up to 15cm across. The flowerhead is made up of many small, shiny violet flowers, and has an open and airy appearance. In 1883 the plantsman Christoph discovered this ornamental onion in central Asia, where it is found growing in the wild. Allium christophii has featured in gardening circles ever since.
In our garden we combine Allium christophii with a medium high Hosta. Give ornamental onions a yearly dose of manure to ensure that they return every year.
