Spiderwort 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, because they are a versatile perennials, valuable pollinator and very modest and adaptable perennials with long flowering period.
Cultivar ‘Osprey’ belongs to “virginiana” group. It offers clumps of grassy leaves, big cool white flowers with feathery violet-blue stamens. Suitable for many types of gardens, including some naturalizing. It is recommend to cut back the clump after first big flower to induce new leaf growth and late summer flowering.
As Tradescantia touches both habitats – sunny and half shade (up to lighter shade), there can be thousands 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.
