Moonshine Yarrow, Fern Leaf Yarrow
A favorite among herbaceous perennials because of the silver-gray green feathery foliage. This yarrow loves full sun in my garden. It’s my favorite Yarrow because the flower are a pale yellow and blooms on straight stalks about 18″-24″ inches tall. Yarrow forms an 18 to 24 inch wide clumps. The blooms last a long time and I deadhead the flowers all summer to promote more flowering. I also don’t hesitate to cut back the foliage to tidy up the plant. Yarrow is both drought tolerant and needs very little water to thrive. It prefers a somewhat sandy well-drained soil. I have divided it and moved it around in the spring with success. USDA Zone 3 to 8.
Licorice Mint Hyssop, Sunset Hyssop
Get this. A perennial that has a fine texture in both flower and foliage. All summer hummingbird appreciate its nectar-rich flowers and for that reason I cut if back by about a 5th every few weeks to keep the blooms coming. Very drought tolerant, it loves a hot, sunny spots in well-drained soil. Place it in the middle or the back of a perennial bed as it get a little over 3′ high and about 3′ wide. As usual, because it is such a solid performer, I suggest buying 4-6 in a smaller size and planting them in a group 3′ on center. USDA Zones 5 to 7.
