Catsear (Hypochaeris radicata) is a common weed, often mistaken for Dandelion (Taraxacum officinale) amongst which it often grows.
It doesn’t have the same medicinal attributes that Dandelion has, which might be a surprise as they share the same soil and conditions.
Every part of Catsear is edible and lack the distinctive bitterness of Dandelions. The old leaves can be stringy and bitter while the young ones are soft. If you grow Catsear in your garden, cover the rosette of leaves while they grow. This blanches them and removes any trace of bitterness.
Stems and flowers aren’t great, but can be eaten in a pinch, while the root can be almost sweet sometimes. It is often dried and ground as a coffee substitute.
The next question is ‘how to tell Catsears from Dandelions‘?
The flowers look so similar that it’s not worth looking at those but the stem beneath them is the distinctive feature. Dandelions only have a single, unbranched, stem, while Catsears have a thinner, wiry stem that may be branched, especially near the flowers.
Dandelions have a hollow stem that bleeds bitter, white latex when broken. Catsear doesn’t.
The leaves are different too. Catsear leaves have less deeply indented and rounder teeth. Dandelion leaves are smooth too, while Catsear leaves are quite hairy.
There you go. If you mix up the two it won’t be fatal but if you’re looking for Dandelions for their medicinal properties, you won’t be happy.
