Scape with leaf-like bracts on the St Bruno's Lily (Paradisea liliastrum)
In botany, scapes are flowering stems, usually leafless, rising from the crown or roots of a plant. Scapes can have a single flower or many flowers, depending on the species. Some show scales, foliaceous bracts and sometimes even branches.
When growing garlic in your home garden, remove the scapes as soon as they come up in order to focus all the garlic's energy into bulb growth, and try cooking with them (use like scallions). [1]
