Which Sweet Pea Seeds Should I Choose for My Trellis?

Match mature plant height to your support before choosing a color. Mammoth Mix and Mammoth Navy Blue are listed at about 70 inches. Incense Mix reaches about 85 inches. Spring Sunshine selections are listed at 72–96 inches, so allow room for taller growth. These are climbing choices, not dwarf patio types; a mini trellis is not the right match for these tall varieties. Choose a mix for several colors, Navy Blue or Burgundy for deeper tones, or Blush and Light Blue for a softer palette.
