Every so often I buy seeds from one company that sells packets for only twenty cents. I bought some nasturtium seeds and on the packet it says to plant these any time between September and February (I live in zone 8b). I can understand this autumn planting for perennials, but nasturtiums? Anyone ever try it that way? Does it give the seed time to get its roots deep into the soil slowly before blooming, working with the life cycle more naturally that way?
