Sweet Alyssum (Lobularia maritima), growing in a novel and heavily sprayed weed ecology on the Jolimont railway embankments, alongside agaves, soursob and various weed grasses. Principally a weed of coastal dunes, this escaped garden ornamental also colonizes high calcium inland soils. Brought to Victoria by 1860 (thanks J. and J. Rule, Richmond, and McMillan & Co., East Melbourne!), Sweet Alyssum had escaped at Port Fairy by the 1880s and along the west side of Port Phillip Bay by the 1920s.
