Cathy Sweet Pea is a tall climber that delivers months of fragrant blooms without the fuss of constant deadheading. At 6 feet, it commands vertical space beautifully, and the fact that deer leave it alone makes it genuinely useful where wildlife pressure is a concern. Bees and butterflies visit consistently, which means your garden becomes a hub of pollinator activity all season long.
Sweet peas are grown primarily for their fragrant flowers, which are prized as cut flowers for fresh arrangements and bouquets. Gardeners grow Cathy specifically for its tall climbing habit and extended bloom season, making it ideal for creating vertical color in borders, along fences, or trained up trellises where its flowers can be easily reached for cutting.
