Common salsify + Yellow pond-lily

Tragopogon porrifolius is a plant cultivated for its ornamental flower, edible root, and herbal properties. It also grows wild in many places and is one of the most widely known species of the salsify genus, Tragopogon. It is commonly known as purple or common salsify, oyster plant, vegetable oyster, Jerusalem star, goatsbeard or simply salsify (although these last two names are also applied to other species, as well).

Yellow pond-lily is an aquatic plant of the family Nymphaeaceae, native to temperate regions of Europe, northwest Africa, and western Asia. This aquatic plant grows in shallow water and wetlands, with its roots in the sediment and its leaves floating on the water surface; it can grow in water up to 5 metres deep. It is usually found in shallower water than the white water lily, and often in beaver ponds. [Wikipedia]
