These are good beginners plants as they grow vigorously and will stand most situations. Deep green glossy leaves have slight serrations and are around 1 cm long, but much thinner. These are held on decumbent stems and will root as they grow making a solid mass of growth, not invasive however. The flowers are produced on short flower stems above the foliage and held in a spike which may be 5 cms tall. Numerous flowers are held in the spike and colour is mid blue.
