How are Hemerocallis measured?
Daylilies are measured by their root size. A heavier, larger root system allows the Daylily to gather more water and nutrients from the soil. Imagine all those roots like straws sucking up water and nutrients.
The more 'straws,' the more benefits the Daylily can get out of the soil. This helps the plant establish its roots more quickly the first year.Once the roots are established, every year you will enjoy a stronger, more beautiful Daylily that boasts more foliage and flowers.
