Flowering Herbs

Create a flowering landscape with herbs.Who says herbs have to be just plain green? Many herbs can hold their own in any flower garden with bright blooms and beautiful foliage. As an added bonus, you can harvest your handsome herbs for cooking or crafts, so they're practical as well as pretty. Many of these attract beneficial insects, too. A flowering herbal border is a great compromise for gardeners with limited space because it does double-duty as an herb garden and a perennial border. The herbs described below are some of the most beautiful and easy plants you can grow for flowers and foliage. The colors are mostly in the pink, lavender and blue range, with silver, bronze or green leaves. White and yellow blooms add splashes of color off and on through the growing season. Anise hyssop Agastache foeniculum This perennial herb grows in bushy clumps, with upright branching stems topped with spikes of lavender-blue flowers in mid to late summer. The flowers attract pollinating bees and other beneficial insects to your garden. Both the leaves and the flowers are fragrant when fresh or dried, so they're a great addition to potpourri. It will self-sow (or grow in new places from seed it drops), so pinch off most of the flowerheads before the small, black seeds mature and drop. Plants grow to 3 feet tall. Zones 4 to 9. Bee balm Monarda didyma The summer flowers of this spreading herb are usually red, but you can also find cultivars with pink, purple or white blooms. 'Marshall's Delight' is a good pink variety that resists powdery mildew, a fungal disease that causes gray patches on the leaves. In mid to late spring, pinch out up to half of the stems at ground level to thin out crowded clumps. Plants grow to 3 feet tall. Zones 4 to 9. Chives Allium schoenoprasum In June, this perennial herb produces pretty pink or lavender flowers that you can add to salads for both color and flavor. The clumps of thin, grasslike green leaves are attractive all season and they have a mild onion flavor. Clumps reach 12 to 14 inches tall in bloom, then arch over gracefully. Zones 3 to 9. Feverfew Tanacetum parthenium Feverfew may look delicate, but it's a sturdy, easy-to-grow herb that blooms from early summer to early fall. The white-petaled, yellow-centered flowers look like tiny daisies. Pinching off the spent flowers can extend the bloom season, and it will reduce the number of self-sown seedlings. You can also cut the whole plant to the ground after bloom for a flush of new growth. Plants grow about 2 feet tall. Zones 4 to 9. Joe-Pye weed Eupatorium purpureum Tall Joe-Pye is the glory of the late summer garden. Its domed clusters of rosy pink to light purple flowers tower over shorter herbs, with sturdy stalks in multistemmed clumps. The flowers attract butterflies as well as lots of attention from garden visitors. 'Atropurpureum' also offers deep purple stems. 'Album' has white flowers. Plants are slow to emerge in spring, so place markers by the clumps. Stems reach 6 to 8 feet tall in bloom. Zones 3 to 8. Lavender Lavandula angustifolia Lavender is as pretty to look at as it is heavenly to smell, and it keeps its distinctive fragrance when dried. In midsummer, English lavender produces spikes of purple-blue flowers on slender stalks over shrubby clumps of narrow, silvery leaves. 'Munstead' and 'Hidcote' are more compact, growing only 12 to 18 inches tall, with dark purple flowers. Lavender is a good choice for the front of the border—it must have good drainage to stay healthy. Zones 5 to 8. Marsh mallow Althaea officinalis Marsh mallow is a beautiful herb that produces attractive pink or white, hollyhock-like flowers for most of the summer. The broad, oval to heart-shaped, gray-green leaves are velvety soft. Plants grow 3 to 4 feet tall. Zones 3 to 8. Meadowsweet Filipendula ulmaria Also known as queen-of-the-meadow, this graceful perennial herb produces frothy clusters of creamy white flowers in mid to late summer. The large, dark green leaves grow in creeping clumps; divide plants every two to three years to control their spread. Plants can reach 3 to 4 feet tall in bloom, although they may be shorter if the soil is dry. Zones 3 to 9. Purple coneflower Echinacea purpurea Purple coneflower produces clumps of sturdy stems topped with large, rosy pink, daisylike flowers that have raised, orange-brown centers. Plants bloom from midsummer into fall, especially if you snip off the dead flowers in summer. The blooms of 'Crimson Star' are particularly deep rose-pink. You may also find cultivars with white flowers, such as 'White Swan'. Plants grow 3 to 4 feet tall. Zones 3 to 9. Rue Ruta graveolens Even if it didn't bloom, rue would be worth growing for its foliage alone. The bright blue-green leaves are deeply divided, giving the whole plant a delicate, lacy look. In midsummer, the clumps are accented with clusters of bright yellow-green flowers. Good drainage is essential for healthy growth. Plants grow 2 feet tall. Zones 5 to 9. Sage Salvia officinalis Common culinary sage grows in shrubby clumps, with oblong, gray-green leaves accented by spikes of purple-blue flowers in mid to late summer. 'Berggarten' has broader, more silvery leaves. If you'd like extra color, try planting 'Purpurea', with purple-green leaves; 'Icterina', with gold-banded green leaves; or 'Tricolor', with green leaves that are splashed with cream, pink, and purple. You can also find cultivars with white or pink flowers. Plants grow 1 to 2 feet tall. Zones 4 to 9. Yarrow Achillea millefolium Common yarrow produces flattened clusters of red, pink or white flowers on slender stems clad in feathery green foliage. These summer flowers are great for fresh or dried arrangements. If you prefer yellow flowers, you could substitute another species or hybrid. Plants are usually around 2 feet tall. Zones 3 to 8.
