    Customer photo review of Sweet Pea Seeds - Royal Scarlet

    (Mid Atlantic) Started in early Jan for bloom mid May with good germination and grown cold during late winter and early spring, and tolerated transplant in March better than expected. I will try starting them directly in ground this November.
