(B/P) to 4′. Early Woad. We obtained original seed from Glasnevin Botanic Garden, Dublin. We have grown this plant for many years and do not see any significant difference between I. praecox and I. tinctoria. We speculate that it blooms earlier than I. tinctoria. I. praecox is a lovely early summer perennial offering sprays of yellow, four-petalled blooms atop deep green, basal foliage. Self-sows. Sun. 3 & T1
