Spanish Heath

Classification: Environmental weed. There is a large invasion of Erica species which originate in the Europe and Africa, many being potential weeds in Australia. Spanish Heath has become widespread in South Gippsland appearing along roadsides and infesting native vegetation. The Erica Baccans commonly sold in nurseries is also a potential weed for the southern regions being very similar to Spanish Heath. Driving round the local roads at this time of year Spanish heath is easy to spot with its white and pink very small tubular flowers. It is an erect shrub growing up to 2.5 metres. Key Points • Spanish heath produces numerous tiny seeds with a life span up to 4years and spreads by wind, vehicles and water and is highly flammable. • If the plants are burnt or broken they readily re grow from the lignotuber or butt. • Small plants can be hand pulled. Mature plants can be cut and painted with herbicide. • Other Erica species are invading native vegetation in southern Australia and species growing in gardens may become weeds in the future if allowed to escape. • Accurate weed identification is essential—weedy Erica species are sometimes confused with native heaths. Our local native Common Heath (Epacris impressa) is often mistaken for Spanish Heath • Apply control methods for Spanish heath to other weedy Erica species.
