Squill bulb

"This species goes dormant after flowering, until the following spring. The bulbs are best harvested just as they flower."

- Zygmunt Budge, Book of Spells.

The bulb of the squill is a structure that functions as food storage organs during the dormant state of the plant. Squill bulbs have potion-making properties, are best harvested just after the plants flower.

Squill are used by Muggles to manufacture cough medicines, while wizards use it as an ingredient for Felix Felicis — renowned Potioneer Zygmunt Budge remarked that it was perhaps the squill that gave Felix Felicis its smooth texture.
