Water Saving Tip:

Replace turf with groundcovers, trees, and shrubs. If you have areas where no one uses the grass, patches that do not grow well, or a turf area too small to water without runoff, consider replacing the turf with water-efficient landscaping.

  • Description

  • Notes

Sweet peas are lovely, old-fashioned annuals with a climbing or mounding habit and sweet, clove-like fragrance. They prefer cooler climates, but by selecting earlier blooming varieties they can be enjoyed, though briefer. Shades of pink, red, purple, apricot, cream, and white. Some modern hybrids aren't as fragrant, so check the seed packet.
Sweet peas require rich, well dug soils with a lot of organic matter. Full sun to a bit of shade. Sow seeds outdoors as soon as soil can be worked. Deadheading prolongs blooming, and the flowers make lovely additions to bouquets. Blooms during spring, before the heat of summer.
