Frequently Asked Questions

How long does Perennial Wallflower actually bloom?

Nearly year-round in mild climates, with peak flowering in spring and autumn — an unusually long season compared to most perennials, thanks to its woody-based subshrub habit.

Is Perennial Wallflower truly a long-lived perennial?

Not exactly — it's technically short-lived, but it seeds itself readily, so new plants tend to replace the originals and keep the display going year after year.
