My Sweet Peas are in full swing right now and beautiful. This very fragrant annual vine is the longest wait that I know from seed to bloom - about 6 months! I planted them in Sept. They began blooming in March. Consider a Tomato or Marigold seedling. They take like 30 days from seed to bloom! Sweet Peas are worth the wait and always remind me of my Grandmother. Mine are taller than our 6 foot fence. The more you cut them for bouquets, the more they bloom and won't spend energy making seed pods. Soon it will be hot and they'll get ripped out. Buy seeds in August.
