Sunstrong™ Orange Improved Erysimum hybrida

Sunstrong™ Orange Improved is an upright wallflower with tangerine flowers in Danziger’s SUNSTRONG™ series. Danziger lists this selection as an early to medium flowering, large-flowered plant that blooms through the season without cooling; its profile gives a mature height of 45–60 cm, spread of 38–45 cm, and zones 6–10 ([Orange Improved profile](https://www.danzigeronline.com/catalog/perennials_catalog/sunstrong-orange-imp/) and [series profile](https://www.danzigeronline.com/series_perennials/sunstrong-series/)). ## Placement and season Use it for spring and summer color in a sunny or partly shaded bed, border, or container. Danziger describes the series as suitable for pots and landscape planting and identifies a delicate scent for the orange selection. North Carolina Extension recommends average to sandy, well-drained soil for Erysimum hybrids and lists borders, rock gardens, and containers among their uses ([Extension growing notes](https://plants.ces.ncsu.edu/plants/erysimum-x-hybrida/)). ## Maintenance Give container plants a free-draining mix and water when the root zone begins to dry. Remove faded flower stems to keep the planting neat, and replace the plant if it becomes leggy after successive seasons; Erysimum hybrids are often short-lived.
