Prasium majus is a small spreading shrub found on stony ground. The purple stems are square in cross section typical of the mint family. The bright green, nettle like leaves are arranged in pairs along the stem, as are the flowers. The pretty white flowers have fine purple lines leading to the nectary. The protruding stamens are also purple tipped. Prasium majus is often found in phrygana, scrambling through bushes.

The leaves can be collected as a type of horta, tsitsiritsa, and used to flavour the little pies, hortopites, or boiled to serve as a starter or side-dish dressed with oil.1
