Sunstrong™ Bicolor Purple Erysimum hybrida

Sunstrong™ Bicolor Purple is an upright, large-flowered wallflower in Danziger’s SUNSTRONG™ series. Danziger highlights its lavender blooms and the series’ first-year flowering without cooling, heat tolerance, and bloom through the season; the series profile lists a mature height of 45–60 cm and spread of 38–45 cm ([Bicolor Purple overview](https://cmp.danzigeronline.com/sun-strong/) and [series profile](https://www.danzigeronline.com/series_perennials/sunstrong-series/)). ## Placement and season Use this selection for spring and summer color in a sunny to partly shaded bed or a roomy container. Danziger describes the series as suitable for pots and landscape planting; North Carolina Extension notes that Erysimum hybrids grow in average to sandy, well-drained soil and suit borders, rock gardens, and containers ([Extension growing notes](https://plants.ces.ncsu.edu/plants/erysimum-x-hybrida/)). Allow about 18–24 inches of height and 15–18 inches of spread. ## Maintenance Keep the root zone well drained, especially in containers. Remove faded flower stems when you want a tidier display, and replace plants if they become leggy after successive seasons; Extension describes Erysimum hybrids as often short-lived.
