Wallflower—Erysimum pureum (Bowles Mauve)
By Pat Adams
Wallflower is in the mustard family. I have the yellow one also but it has just started blooming. The leaves are grey-green with clusters of fragrant purple flowers. The fragrance is heavenly and when the sun shines on it or if a breeze blows over it you can smell it without being near the plant. It is especially fragrant at night. It is classified as a perennial but often grown as a biennial or annual. It is not picky about soil because I have one that came up last year and came back this year in gravelly sandy soil. It is drought tolerant. When it gets hot it will die back and I just cut it off close to the ground so it doesn’t look ugly in the garden.
