This selection is listed as heat tolerant and long blooming, with spring and summer flowers and fall color as temperatures cool. ## Site and water Give it part sun to full sun, well-drained soil, and average moisture. The developer notes that it prefers evenly moist conditions and can show drought stress, especially in a hanging basket. Its listed hardiness is USDA zones 9a–11b. ## Maintenance Deadheading is not needed for continued bloom. Trim trailing stems if they spread across a walkway, and check container moisture during warm weather.
