Varieties of Hyssop

Hyssop is a perennial herbal plant of the mint family that grows tall spikes of flowers amid full green foliage. Its colorful blooms can last for several months during its growing season, typically the summer and early fall. The nectar of most varieties is very attractive to birds, butterflies and bees. The flowers are edible and have medicinal properties, as do the leaves. Naturopathic medical practitioners use hyssop tea and hyssop essential oil to loosen phlegm and treat colds and other respiratory ailments. Varieties of hyssop come in a range of colors and fragrances.
  1. Anise Hyssop

    • Anise hyssop (Agastache foeniculum) derives its common name from its licorice-scented foliage and flowers. Anise hyssop also has fragrant undertones of its relative, mint. The flowers of this variety are lavender and attract bees, butterflies and hummingbirds. Anise hyssop thrives in full sun and moderately moist to dry soil that is well drained. Anise hyssop can grow three to six feet high, and it blooms from early summer through mid to late fall.

    'Blue Fortune' Hyssop
