I had great success with this F1. Germination rate was excellent but I did find the stems were not as sturdy as I would have liked. I do pinch mine back to get more blooms and ended up at about 3feet tall (including the blooms) with 3 flower spikes per plant. And the colours are perfect. The white is bright and the pink center is lovely - it's a bloom fit for a fairy princess.
We are incredibly happy with our own personal meadow.
