An emerging weed, Hedge Woundwort (Stachys sylvatica), has been observed along Splitters Creek, Valley View Lane, and properties on Baldrys Rd. This is a rhizomatous plant that thrives on the edges of woodlands, damp areas and

unmanaged pastoral land. Landcare and Melbourne Water are working to eradicate it from along the banks of Splitters Creek between Baldrys Crossing and Main Creek Road but Hedge Woundwort also has been observed spreading beyond the riparian zones. The recent wet conditions and flooding along our creeks will have assisted its spread.

A good description and several images (including the one here) can be found at Vic Flora, who also provide the following description.

Hedge Woundwort is an erect, unpleasant-smelling perennial herb which can grow 80cm – 1m tall; however, it can also have a sprawling habit. The stems are squarish with nodes from which leaves sprout in opposed pairs. The leaves are 10cm long, oval and pointed with toothed edges. Both leaves and stems are extremely hairy.

The flowers which are reddish purple with white markings and about 6-8mm long form in whorls along a leafy spike-like inflorescence during summer and autumn. It spreads by seeds and via slender underground runners known as ‘stolons’. Experience indicates that the seeds can travel some distance.

The only other recorded Victorian occurrence is in the Dandenongs, so quick action here could prevent yet another nasty weed getting hold. If you suspect you have an infestation, please contact Michelle Stacy, for information on how to tackle it.
