Dekko™ Deep Lavender Vein Petunia

Dekko™ Deep Lavender Vein is a spreading annual petunia selected for its lavender-toned flowers with darker veining. Syngenta lists the cultivar at 8–12 inches tall and 18–22 inches wide, with flowering from early spring through summer. The compact, spreading outline suits mixed containers, baskets, and sunny beds where its patterned blooms can be seen up close. [Syngenta Flowers](https://www.syngentaflowers.com/ams/product/flower/70076420) ## Growing conditions Give it full sun and fertile, moist but well-drained soil; University of Illinois Extension notes that petunias perform poorly in very heavy soil. Container plants dry more quickly than in-ground plants, so check moisture regularly and water before the root ball dries through. Leave room for the plant to spread, and avoid planting it where neighboring plants will shade it. Treat it as a warm-season annual in cold-winter gardens.

If stems become leggy late in the season, a light pinch can encourage a more compact outline; remove damaged growth as needed. Avoid routine heavy cutting that would remove flowering tips.
