Frequently Asked Questions

Why is it called Wallflower?

It naturally thrives on rocky slopes and old walls, growing happily in the thin, well-drained soil found in crevices — which is exactly where it earned its common name.

Will Wallflower come back on its own next year?

Often yes — as a biennial or short-lived perennial, it self-seeds readily in suitable conditions, so new plants frequently replace the originals in rock gardens and borders.
