These remains were seen at the Reader Rock Garden recently. "Originally from Central Asia it is now found worldwide, spread largely due to its use as a herbal remedy. L. cardiaca, a member of the mint family, has a square stem and opposite leaves. The basal leaves are wedge shaped with 3 points while the upper leaves are more latticed. Flowers appear in leaf axils on the upper part of the plant and it blooms between June - August. The flowers are small, pink to lilac in colour often with furry lower lips. The plant grows to about 60-100 cm in height. It can be found along roadsides and in vacant fields and other waste areas." From Wikipedia.

I never knew what to call these before - dead flowers? Now, thanks to Doug, I know that the correct word is "receptacles"! Not sure if these are Aster receptacles. They always catch my eye when I'm out for a walk.
