Hybridizes with : Skullcap (Scutellaria garlericulata) to produce Scutellaria × hybrida which occurs near the parents and is very sterile but spreads vigorously vegetatively.

Uniquely identifiable characteristics

Distinguishing Feature : The twinned pinkish flowers sitting just above a pair of opposite leaves on a square stem, both flowers pointing in the same direction.

Lesser Skullcap, according to some, now only grows just South of London and near Portsmouth, but there are some rare and isolated outbreaks much further north, like here for instance, or other places such as the IoM and north up to the Hebrides. Like Skullcap it is native. It grows in wet grassy places, wet heaths and open woodland on acid soils.
