  • circleLife cycle

    The life cycle of Erysimum × marshallii 'Orange Monarch', commonly known as Wallflower, begins with seed germination, which typically occurs in spring or autumn under favorable moisture and temperature conditions. Seedlings then develop into juvenile plants with a rosette of leaves close to the ground. As the plant matures, it sends up one or more flowering stems, which bear clusters of orange flowers typically in the spring, but it can bloom throughout the growing season. After pollination, which is often facilitated by insects, the flowers develop into long, narrow seed pods known as siliques. Upon maturing, these seed pods split open to release seeds, completing the reproductive cycle. The plant is a short-lived perennial or biennial, and after flowering for one or more seasons, it will eventually senesce and die, although it can self-seed under the right conditions.

      Spring to summer

    • Erysimum × marshallii 'Orange Monarch', commonly known as Wallflower, is frequently propagated through semi-ripe stem cuttings. This method is most effectively carried out in late summer. When propagating 'Orange Monarch' from cuttings, one would select healthy, semi-ripe stems and cut a 3 to 4-inch (approximately 7.5 to 10 centimeters) section just below a leaf node. The lower leaves should be stripped, and the cutting may be dipped in rooting hormone to encourage root development. The prepared cutting should then be inserted into a pot filled with a well-draining potting mix and kept moist. It's important to place the pot in a warm, bright place but out of direct sunlight to allow roots to establish. With proper care, the cutting will develop a robust root system that will eventually enable it to be planted out into the garden.
