October and even early November are the perfect times to be sowing sweet pea for flowers next spring. As well as annual sweet pea there is also a perennial everlasting pea which also produces masses of blooms but can be a bit of a thug if not contained and can even be invasive in some areas. I'm sowing both varieties this year for flowers next year. Both are quite tough and can withstand the cold pretty well but young plants will need a bit of protection over the colder months.
