good winter grower here and good to save seeds on too--you should only ever have to buy seeds one time; a super easy annual to grow--and it is highly scented

According to the SSE catalog, this sweetpea was discovered in the 1730's, growing in a planting of 'Cupani'. It is also the very first bi-color. Blooms over a long period of time and is very prolific. 5-6 ft tall annual.
