Tweedia brings a sky-blue splash to your New Jersey garden, with velvety downy gray-green heart-shaped leaves and star-shaped flowers that bloom from summer into early fall. This tender perennial (hardy zone 8+), treated as an annual locally, thrives in full sun with well-drained soil. It has a climbing or trailing habit, but needs support to climb. Beloved by butterflies, it adds charm to cutting gardens, making stunning additions to bouquets with its long-lasting blooms. Heat-tolerant and resilient once established, Tweedia is a rare blue gem that brings elegance and pollinator appeal to your summer landscape. Pinch back stem tips in spring to encourage branching. Its downy leaves and milky sap deter herbivores, making it unappealing to deer and rabbits.
