Spiderworts are still underused perennials in our yards. Maybe because we can still see some wild colonies of native spiderwort in the countryside, but even the wild forms should be present in our gardens - they are versatile use perennials, valuable pollinator plants and very modest and adaptable perennials with longer flowering period.
'Concord Grape’ belongs to “virginiana” group. It offers more compact clumps of grassy leaves (about 12" tall), over 1" big, dark purple- pink flowers nicely contrasting with gray-green leaves. And long flowering period is obvious.
Suitable for many types of gardens, including some naturalizing. It is recommend to cut back the clump after first big flower to induce new leave growth and late summer flowering.
As Tradescantia touches both habitats – sunny and half shaded (up to lighter shade), there can be thousand of great perennial combinations of both. In sunny border plant it with perennials like Aquilegia, Geranium, Hemerocallis (daylily), Iris x germanica, Knautia macedonica, Monarda, Paeonia, some species of Nepeta (N. subsessilis, N. kubanica, even N. x faasenii), Salvia nemorosa, Sedum telephium. In half- shade spot it goes well with Amsonia, Heuchera, Geranium, Iris, early flowering woodland Phloxes like Phlox divaricata or non-native perennials like Brunnera, Bergenia, Hosta. Looks well with grasses and ferns too.
