Acanthus spinosus is an herbaceous perennial. There are other species but this is my favourite as I prefer it's more dissected, thistle-like leaves. A mature clump in flower is an impressive site. Scroll down this board for further details.
Pratia or White Star Creeper is a herbaceous perennial groundcover used as a lawn substitute, as fillers in pathways, in rock gardens and in borders. A profusion of starry white flowers bloom spring through summer, followed by globular, reddish-purple fruit in autumn, attracting birds. This plant will tolerate wet or dry conditions in sun or shade. Low growing (2-3" tall). Zones 5-10
