Betony - Stachys officinalis

Selfheal - Prunella vulgaris

Meadow Clary - Salvia pratensis

This plant grows in tall spikes up to a metre and a half. It grows from a basal rosette of leaves. It has a hood like upper lip to the flower. It's quite rare now in England and is a protected species but fairly common in the rest of Europe. It is mainly to be found on good quality chalk grassland. It needs some patches of bare ground to allow seed germination so it might typically be found growing near rabbit warrens.
