UID 8Y-Y "Hattie's Chartreuse"
For whatever reason, the vagaries of life entice these two tazettas to bloom at very different times year to year. Sensitive to a climatic trigger yet determined, they may bloom early or late within a two month window. Both are thought to be "older" cultivars, one not much beyond an improved species, the other mid-1800s hybrid. Another habit both share is the inclination to multiply.
