Could be confused with:

Hemlock water dropwort (another member of the carrot family). This can be deadly poisonous. Among the many differences the key ones are that the leaves of hemlock water dropwort are more finely lobed. Hemlock water dropwort typically grows in damper locations than Alexanders, on river banks or above an underground water source. When in seed it’s easily distinguishable as Alexander seeds are jet black and hemlock water dropwort seeds are not. Hemlock water dropwort has clusters of yam-like tuberous roots whereas Alexanders has a single main tap root which is obviously jet black/dark brown.

Watch out for the vibrant green but camouflaged caterpillars of the Angle Shades moth that can be hard to spot.

On top of the stem sits an umbelifer or flowering dome of yellow-petalled flowers, making it easier to distinguish from other plants in this family as their flowers are typically white.

Tips and Observations

Use a knife to cut away from young tender leaf stems, cutting below the surface of the soil, up to 3 inches, you’re looking for the white parts of the stem which is most tender.

Specifically noted the angle shades moth caterpillars which are almost the same colour as the foliage (if collected in March) so requires good washing to make sure it’s removed.

If you find the flavour too strong on trying this plant raw as an herb for the first time, cooking really moderates and loosens the pungency of flavour, making it more palatable.

Identification is key!
