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

Calistoga yarrow is in all ways similar to the species, except that its foliage is more silvery grey. Peach to yellow flowers bloom late spring to early summer. Attracts butterflies; is unattractive to deer and rabbits. Grows about 2 to 3 feet tall and wide.
Many different cultivars of Yarrow are available, with different flower colors, including yellows, reds, peaches, and pinks. Yarrow makes a good ground cover when mowed, and tolerates a fair amount of foot traffic. Divide in the spring every few years as the centers can sometimes melt out. Grow in full sun to part shade in well drained soils. Tolerates clay soils. Yarrows are best not planted next to slower-growing and smaller perennials, as they may overtake and overwhelm them.
