About Wallflowers
Erysimum, commonly known as wallflower, is a genus of roughly 180 species in the mustard family (Brassicaceae), native across temperate Eurasia, North Africa, and the mountains of North America south to Costa Rica. Growth habit ranges widely across the genus, from annuals and biennials to short-lived herbaceous perennials and small sub-shrubs, with narrow, often gray-green leaves and clusters of four-petaled, cross-shaped flowers carried along tall, slender spikes. Most Erysimum sold in gardens today are complex perennial hybrids, many tracing back in part to the classic 'Bowles' Mauve', prized for an unusually long bloom season, a sweet honey-like fragrance, and flowers that open in shades of yellow, orange, pink, red, and purple from mid-spring well into summer. Low-maintenance and drought-tolerant once established, they thrive in full sun and sharply drained soil, and are a steady draw for bees, butterflies, and hummingbirds.
