Heath Milkwort

Heath Milkwort - Polygala serpyllifolia

Description

Distinguished from P. vulgaris by having opposite lower leaves. The flowers are usually blue, but pink and white flowers do occur, sometimes in the same colony as blue flowers.

Similar Species

Common Milkwort (Polygala vulgaris) has alternate, not opposite, leaves.  Chalk Mikwort (Polygala calcarea) has been recorded in VC55, but only on a few sites in limestone areas; it has larger lower leaves clustered into a rosette.

Identification difficulty
ID checklist (your specimen should have all of these features)

Lower stem-leaves opposite; heathland or acid grassland

Recording advice

Records from this species should be confirmed by a County Recorder for botany.  It is on the VC55 Rare Plant Register, and therefore a specimen should not be taken.  Take detailed field photos and submit to NatureSpot as soon as possible; and if you think you have found it in a new location, inform the County Recorder as soon you can.
