Sunstrong™ Orange Wallflowers are robust, bold, and easy to maintain. Their dainty flowers have a vivid tangerine hue and bloom in clusters for an even bigger, more impressive display. Erysimum linifolium blooms from early spring through the first frost. The long bloom season means you’ll have plenty of time to enjoy the fragrant flowers.
This charming plant lends a cottage vibe to a mixed bed or adds color to a border. The compact size of the Sunstrong™ Orange Wallflower plant makes it ideal for containers. The blooms welcome pollinators, including butterflies, to an area. This plant is heat tolerant and will hold up nicely in warm summer weather.
Sunstrong™ Orange Wallflowers Care
Plant in fertile, moist, and well-drained soil. Select a location that receives full to partial sun. Morning sun and afternoon shade are best in areas with warm summer weather. Water consistently and deeply for the first growing season. Established plants are drought tolerant, but bloom more reliably with water during a dry spell. Fertilize each spring to support growth.
The Sunstrong™ Orange Wallflowers grow as an herbaceous perennial in zones 6 through 9. Trim all growth to ground level after the first frost and apply a layer of mulch to insulate the roots from cold temperatures.
Sunstrong™ Orange Wallflowers Spacing
Sunstrong™ Orange Wallflowers stand 20 inches tall and 18 inches wide. Grow two plants in a 12-inch container or space landscape plants 18 inches apart, center on center.
