The leaves of the allium giganteum are long and oval and they are a bright green color. But perhaps the most distinctive part of this plant is the flowers it produces.
There are many tiny purple flowers that make up a complete allium giganteum flower head. These tiny flowers are assembled in a circular pattern to form one round flower. A long stem extends from the flower to the ground and there are no leaves on the long stem.

When using these types of flowers in an established garden it is suggested that a different source of ground cover foliage be used. The long, spindly leaves that rest on the ground are not very attractive but can be camouflaged by another ground cover plant. If you would like to boarder off any area using these ornamental onions it is a good idea to plant them only a foot apart. There are no leaves or foliage that covers the stems, so there may be big gaps in the spacing of these plants.

The only thing to be concerned with while caring for these plants is over watering. It if live in an area that receives a lot of rain you may consider a raised, straight lined bed for planting these flowers. Too much water can do damage and even kill these types of plants. You will have to insure that no water will ever puddle around the root area. Proper drainage is most important when dealing with these flowers. If you cannot make raised bed due to too many rocks, you can prepare your soil first. Mix some medium and small sized rocks into the soil around the roots. This draws water away from the root area. Only water these plants once a week and make sure the soil is completely dry, before adding any more water to them.
In the spring when the plant begins to start growing again, there may be brown discolored leaves left over from the last season. If this is the case gently remove these leaves by snipping the brown areas off. Never yank or grab any roots out of the flower area.
