What are your plant identification skills like? Sometimes there are plants that look different and so your first thought is that it is a weed. Lawrencia spicata, Salt Lawrencia may look like a weed, but it is a rare native plant often associated with salt marshes. These photos were taken near the Ross Bridge Flora Reserve, south of Ararat. The reserve and roadside is mapped as Western Plains Basalt Grassland. Thanks to Frank Carland for supplying the photos.
Salt Lawrencia is a perennial herb that has tall cylindrical flower spikes with white or yellow flowers. The leaves are distinctive and have a long stalk (petiole) and it grows from a rosette. Vicflora has some close up images
