Can sweet peas be grown in pots?

Do these seeds make a good gift?

Yes — this is a straightforward packet to give, and what makes it work as a gift is mostly timing. Sowing runs January to May, and October to December, so a packet given inside that window can go straight in, and one given outside it keeps perfectly well until the season comes round. There are approximately 20 seeds in the packet. On effort it looks after itself, which matters if you are giving it to someone new to growing. It suits pots, beds and cut flower displays, so it works for a small space as well as a garden.
