- Cheryl D.AL, United StatesVerified ReviewerRated 1 out of 5 stars9/23/26Three Seasons - Zero Germination
I love BI seeds and find them very reliable, but these were consistently a no-show for me. I’ve tried in two different beds and a Greenstalk and got zero germination.

These germinated fast and grew big enough to transplant very quickly. The seedlings are struggling a bit in the ground, but the weather has been cold and wet lately. I think they'll recover well enough once it gets reliably warm outside.

Germination was good but all of the flowers ended up white! I was hoping for the vibrant pink colors.
