What makes this plant tricky to grow is that it is coming up when gardeners are busy raking leaves and ripping out spent annuals and perennial stems. One must be careful not to trample or weed out these new seedlings. Also these plants prefer a shaded, moist site. I had some in full sun and they were cooked after a couple of days of warm spring weather.
Other species of US native annual Collinsia, hailing from the western states, are C. grandiflora (Blue Lips) and C. heterophylla (Chinese Houses). Seeds for these plants are more easily obtained.
