Erysimum menziesii, commonly known as Menzies’ Wallflower, is an evergreen biennial or perennial herb native to coastal dunes and bluffs in California, particularly in the Central Coast region. It typically grows to a modest height of not more than 15 centimeters. The plant has a basal rosette of leaves that are often thick, hairy, and lobed, with narrower leaves higher on the stem. The inflorescence is a dense cluster of bright yellow flowers, which are highly attractive when they bloom in the spring. The flowers give way to elongated siliques, which are seed pods that stick out from the stem. Menzies’ Wallflower can exhibit variation in form, especially among subspecies.

This wallflower is valued for its vibrant yellow flowers that can add a splash of color to rock gardens, coastal gardens, and native plant landscapes. It is drought-tolerant once established, making it suitable for xeriscaping and low-water garden designs. Menzies’ Wallflower thrives in well-drained soils and can tolerate sandy conditions, reflecting its coastal origins. It prefers full sun to part shade and requires minimal maintenance. While generally disease-free, it can be susceptible to root rot if overwatered or planted in poorly drained soils.CC BY-SA 4.0
