These plants are usually from tropical or subtropical regions so are highly vulnerable to frost. Seeds need warm soils to germinate. Most annuals are categorised as tender (e.g. marigolds).
Okay, I planted two of these seeds in my hydroponic table, and in les than 72 hours they have germinated and the first 2 baby leaves are showing. the germination was incredibly fast and I will buy from this store again sometime
Good quality product and maintaining its structure despite a VERY wet growing season.
