Known to be nearly indestructible, this is an excellent choice for growing between flagstones or growing as a lawn substitute. It forms a dense evergreen carpet, becoming bronze in winter. The tiny leaves are green with an edging of creamy yellow, with tiny spikes of creamy-yellow flowers in summer. Tends to need watering during periods of extreme drought. Sometimes used in formal carpet bedding schemes. Growth rate is fairly slow and easy to control. Rupturewort is a relatively unknown perennial that deserves to be used more often in our gardens. Discovered by David MacKenzie in his Michigan garden. USPP#15989: unlicensed propagation prohibited.
