#1 Marsh Marigold – Caltha palustris
General Description: Buttercup-like flowers 1-1.5″ 5-9 deep yellow sepals (appear as petals). Heart-shaped leaves are deep green. Stems are hollow and succulent. In flower from April to June.
Uses:It is the yoiung leaves and flower buds that are used in the early to mid spring. The leaves NEED to be boiled in 2-3 changes of water for 20 mins. as they contain poisons that need to be boiled in order to make them edible! Once boiled the young leaves are quite tastey and very appreciated as some of the first edible greens of the year. Remove the stalks from the leaves before boiling. The young flower buds can be boiled for 10 mins in two changes of water and ‘pickled’ in vinegar.
