This fantastic little flowering perennial is compact, and grows in a low mound with fine-textured gray-green foliage! Great even if you don't have a yard at all! Like a carpet of aromatic color, these form compact mounds of licorice-scented gray-green foliage!
Also called the Hummingbird Mint, those silvery-blue trumpet-shaped blooms are perfect for Hummingbirds! So colorful and long-lasting, the spikes start shooting up in June and keep popping until fall - much to the delight of local honeybees and butterflies in your neighborhood!
Staying compact and just 18-24 inches tall and spread to a wide 24 inches! These are wonderfully space-saving herbaceous perennial plants that are a joy to take care of - because they require almost no care at all! The Kudos™ line of hybrid Anise Hyssops are cold and heat-tolerant throughout USDA growing zones 5 through 10 and is generally deer and rabbit-resistant, adaptable to xeric locations, and once established can be very drought-tolerant little beauties!
Planting and Application:
Silver Blue Hyssop forms a creeping, low-growing, and compact mound that is perfect to use as colorful edging along garden beds, or as facer plants along the foundation and hedge plantings! Line a path or walkway in vivid Silver Blue blooms - you can enjoy brushing past that wonderful scent! Fill a hillside in the sun with bright color en masse or simply spruce up a mailbox so no one misses the turn into your driveway again!
Use Silver Blue Hyssop for mid to late-season accent around poolside and seating area plantings - both in the ground or in colorful containers! Tuck into planters on your porch for welcoming color! These sunny blooms just won't quit! Add pots around a balcony so that the same mounding growth makes Silver Blue Agastache perfect in pots and planters as spillers and fillers!
Hyssop perennials not only look terrific, but they are also a vital nectar resource for beneficial pollinators and our precious native bee populations. No Butterfly Garden is complete without an Anise Hyssop and migrating Monarch Butterflies and Hummingbirds get their fill of nectar for the journey!
Partner these wand-like flowers with other Hyssops for a varied height mixed-perennials display! Or mix with other perennials of all kinds. Pair with purple and pink flowers, coral and peach, and of course white and blue flowers! Perfect facer plants for large or small shrubs to hide their bare lower stems, and look fantastic with blue, white, or pink Roses!
Enliven a garden bed or border with flowers that will still be blooming long after many other plants stopped in the summer's heat. Don't forget to get one for yourself as a fragrant addition to a Sensory garden, add to a Cutting Garden for colorful bouquets all growing season, or bring butterflies to your Cottage Garden. Plus xeric color to a Rock Garden in the front yard. These front-of-the-garden accents look great all season long.

#ProPlantTips for Care:
This saucy little hybrid Agastache is a low-maintenance clumping perennial perfect for a full sun location, in very well-drained soils. Appreciating the drying power of the morning sun to keep the scented foliage healthy and mildew-free! Deadhead to encourage rebloom and keep the plant neat and tidy. Prune back the stems in late fall, mulch the crown well, and water in well for the winter.
Thriving in drier soil once established, Hyssop can be highly drought-tolerant, but you'll get the best performance with a regular schedule of supplemental water. Although this plant does well in thin, poor soil, protect your investment and encourage healthy roots by using Nature Hills Root Booster at planting time to help your plant uptake nutrients in the soil more efficiently.
