    Tradescantia sillamontana plant details

    Irresistible to touch, The Cobweb Spiderwort is covered in velvety soft webbing, a good tactile element for the sensory garden. The soft pinkish-purple flowers are pretty against the silver leaves. Gently spreads to form a nice low clump that looks especially smashing perched at the edge of walls and pots. There are varying reports of cold hardiness, zone 9 is probably a safe bet, but with good drainage and a protected spot, it's been reported to overwinter in zone 7 (we'd guess that's if cold snaps are not prolonged). Even when grown as an annual in colder, wetter climates, it's a welcome addition to the summer garden. As an easy-going plant that prefers a bit of neglect with little water, good drainage, and a somewhat sunny spot, they're good companions for succulents like sedums and sempervivums.

    Tradescantia sillamontana is a broadleaf evergreen or semi-evergreen perennial groundcover with blue foliage. In summer lavender and magenta flowers emerge. Features fuzzy texture. Grows well with sun - mostly shade and regular - low water. Drought tolerant once established. Does well in average and well-drained soil. A good option if you're seeking something verticillium wilt resistant.

    Fuzzy leaved spiderwort, appearing as if its pale green leaves were covered with...yes... spiderwebs. Low growing and spreading, to 10-12” x 18”, with striking magenta flowers in summer through autumn. Showy in containers or the garden. Found in the mountains of northern Mexico, they prefer sun and are easy growers, needing little water and generally thriving on neglect. Frost hardy in UDA zone 7 in a well-drained environment.

    White Velvet Tradescantia. This gets great cobwebby silver-white foliage with light purple flowers nestled in the leaf axils. Likes it on the drier side thank goodness. Far hardier than we thought, this overwintered in the ground outside at plant maestro Brian McLaughlin's garden at 10 degrees.
