Xtreme™ Lilac Impatiens

Xtreme™ Lilac is an F1 color variety of Impatiens walleriana in Syngenta’s Xtreme™ series. The breeder lists a mounding plant 8–10 inches high and wide, flowering from mid to late spring through summer in full or part shade; the product page gives hardiness zone 11a. The [Syngenta product page](https://www.syngentaflowers.com/ams/product/flower/70007942) identifies this exact selection and its growing details. ## Placement and growth Use this compact annual in shaded seasonal containers, packs, or landscape beds. Syngenta describes the Xtreme series as uniform and early flowering, with short internodes and branching. The Lilac listing gives an 8–10 inch garden height and width; these are ranges, so no single mature measurement is implied. ## Soil and water Iowa State Extension’s guide to [garden impatiens](https://yardandgarden.extension.iastate.edu/how-to/growing-impatiens-home-garden) says I. walleriana performs best in moist, well-drained soil and partial shade. It can grow in heavier shade, though plants may become taller and flower less. Check container soil frequently and water when its surface dries; garden beds need water during dry periods. ## Maintenance Plant outdoors after frost danger has passed where that is relevant to the local climate. Keep the root zone evenly moist without leaving containers waterlogged, and adjust watering for heat, shade, and pot size.
