Sweet peas

Absolutely, growing sweet peas in a hanging basket is not only possible but can be quite charming! Ensure your basket has good drainage, use a quality potting mix, and provide support for the vines. Regular watering and deadheading will promote more blooms. Give it a try, and enjoy your sweet peas cascading down in a unique display!

I’ve just bought a packet off EBay. Apparently they will also grow in containers and are good for groundcover. Also sweet perfume. We shall see.

My experience has been they do much better in the soil, their roots need more room than even a large pot provides

I bought some sweet pea plants, specifically for hanging baskets, a few years ago, but they were very disappointing despite dead-heading every day. I won't be bothering again.

My dear friend (I) used to grow them in pots, hanging baskets etc. She loved her sweet peas. Wish she was still with us. I would have asked her for a few tips and passed them on to you.🥲

Yes, you need a variety which is specifically for hanging baskets. The ordinary ones won’t be suitable, too tall/long.

I think you need sweet peas that are specifically for hanging baskets. You can do ordinary culinary peas in a basket to eat the pea shoots but you need a low growing variety.
