Thanks for the story and the information of the plants. That's what I learned about this flower.
MARGUERITE DAISY. This hardy chamomile is one of the best options for summer color on the solar boundary. Plants form a shrub mound of green green foliage, carrying loads of small bright yellow camomiles, since the beginning of summer. Excellent for planting in bathtubs and mixed containers, as well as for fresh cut flowers. Short-lived perennial, but will re-sow itself. Grow 24-30 inches tall in full sun or particle.
