I love Sweet Peas.  Every year I look forward to being charmed by the Sweet Pea’s beautiful flowers and romanced by their heavenly fragrance.  Sweet Peas are certainly an annual that I recommend you try growing.  Sweet Peas, which are also known by their botanical name of Lathyrus odoratus, are very versatile, here in the UK, you can sow their seeds from September right through until April.
