We have updated our Milfoil (Myriophyllum species) identification guide to reflect the new classification of Myriophyllum ‘Red Stem’ to Myriophyllum rubricaule.

The Guide was first launched in 2022 during Invasive Species Week to help retailers identify the correct Myriophyllum species that can be sold.

Two species are currently banned from sale: Myriophyllum aquaticum and Myriophyllum heterophyllum. However, these can sometimes be mislabelled so the guide outlines the idenfiers to look for to ensure the correct plants are being sold.

At the time of the original launch, Myriophyllum ‘Red Stem’ had not been classified so the guide has been updated to reflect its new name Myriophyllum rubricaule.
