Perfoliate Alexanders - Smyrnium perfoliatum

Description

Superficially similar to Alexanders (Smyrnium olusatrum) with umbels of yellowish flowers, but only grows to about 60cm, half the height of Alexanders, and has yellowish-green leaves rather than the dark glossy green of Alexanders. Another difference is that the leaves strongly clasp the stem, encircling it.
