About Spiderwort

All are zone 9b-hardy, producing three-petaled blooms in pink, purple, or white from spring through fall, and valued for both colorful foliage and pollinator appeal. Starting at $6.95.

Care essentials
Light
Tradescantia performs in full sun to partial shade; T. pallida (Purple Heart) thrives in full sun with the best foliage color, while T. ohiensis (native spiderwort) and trailing forms prefer partial shade in NE Florida's intense summer heat.
Water
Water regularly to maintain moderate soil moisture; established plants tolerate short dry periods, but consistent moisture during summer promotes fuller growth and extended bloom — cut back in midsummer to refresh.
Soil & Fertilizer
Adaptable to a wide range of soils including sandy, loamy, or clay, with moderate fertility; light feeding in spring with a balanced fertilizer is sufficient — avoid high nitrogen, which promotes foliage over flowers.
