This knockout herbaceous perennial is evergreen, with soft, rounded silver leaves that look like pewter. Native to Arizona, New Mexico, Texas and northern Mexico, it thrives in climates such as Austin, TX, where these photos were taken. Although not especially cold hardy (to 20-25º F), it is fast-growing and is a popular annual in colder climates. Often selected to cascade out of planters and pots, it also makes a durable and lovely groundcover, rooting along the stem nodes if soil is available. Silver Ponyfoot needs good drainage, and will appreciate some afternoon shade in the hot low deserts.
