|How are Lilies measured?|
Lilies are measured based on the circumference of the bulb. The greater the circumference of the bulb, the more food can be stored by the plant to give it a better start and greater success.
A larger bulb will produce a fuller plant with more flowers, giving you a more beautiful garden. A 16/18cm Lily will produce 2-3 stems per bulb versus a smaller bulb size.
