Comments:
Year 1:
Plants in northern areas did not flower. Very similar to a marguerite daisy flower. Not special enough to put up with the height. The flowers opened slowly so it did not flush; Please let us know how to get flowering on shorter plants! Cut back when? The flowers are a nice spray (like Rudbeckia triloba and nice color); Maybe next year. The few flowers I saw were nice; Good size plants but no flowers.
Year 2:
Had to transplant to more open area because of height of plant. Planted in drought area so had no flowers. Hope to have a better report next year.
