The Yellow Bell belongs to the lily or Liliaceae family. It has an erect stem with lance-shaped leaves and can grow to be about 4-12 inches tall. The flowers are yellow and they nod towards the ground. They are also shaped like a bell, hence the common name, Yellow Bell.
The bulbs of the Yellow Bell are edible and are quite tasty. They can be eaten raw or cooked and can be a nice addition to soup. However, it would take killing many of these beautiful little plants to create a meal. Personally, I think it would be a shame to kill large amounts of this lovely little plant to eat, unless it's absolutely necessary.
Remember, if you are going to pick wild food from nature try to take less than 10% of what is there. That way the population can sustain itself and you and future generations can continue picking wild edibles for years to come.
Also, beware that many plants in the lily family are quite poisonous and eating them can lead to death. Many lilies can look quite similar when they are young. Please take great care and have a solid grasp of plant identification skills before you ingest any wild plant material.
