If you are looking for a vibrant, unique flowering bulb, consider planting allium (also commonly known as ornamental onions). These showy globe shaped flowers are available in shades of white, purple, yellow, and blue.
Tips on Growing Allium
Allium is easy to grow and they generally deter animals.
Find a location where the soil is sandy or has good drainage, avoid soggy areas as this can cause root damage. Alliums need full sun to develop sturdy stems and full blooms.
Plant these bulbs in the fall along with your cherished tulips, hyacinths, and daffodils. Depending on which variety, you have, your alliums will bloom from spring to mid-summer, so consider this when you are deciding to place them. A small handful of bone meal in the soil when you are planting will help with root development.
Always follow the instructions on the back of the bag and always remember: pointy side up! A general rule of thumb for planting: you want to dig a hole that’s at least three times the height of the bulb.
For example, if the bulb is 1” tall you should dig a 3” deep hole to plant it. This is true for many spring flowering bulbs like tulips and daffodils.
What to Plant
Long before allium ‘Millenium’ was announced as 2018 Perennial Plant of the Year®, gardeners and landscapers had their eyes on the globe shaped bulb. As UltraViolet was named PANTONE® Color of the Year 2018, the timing could not be better for this perennial to be flattered in the gardening world.
This variety gets its name from the twisty foliage that is evocative of the legend of Medusa. This plant’s grey-green, narrow foliage has a slight twist at the end with clusters of light, amethyst purple flowers.
Allium ‘Rising Star’
This petite perennial maintains a small stature and trim figure. This beauty blooms lavender-pink flowers from May to June. Its small size makes it ideal for the front of the garden bed or in containers.
