There’s a Scientific Reason Why Some People Think Cilantro Tastes Like Soap
This biennial develops ferny foliage its first year in the garden and bears white flowers and seeds the second year. The seeds are most commonly used to flavor rye and other breads, but all parts of the plant are edible. Caraway prefers a sunny location with rich, well-drained soil. Although the plant tolerates drought, don't let the soil dry out completely.
Comfrey leaves are full of nutrients that make a natural high-potassium fertilizer or addition to compost. This perennial herb sends down deep roots that pull nutrients into the plant's large, hairy leaves. It grows best in moist sites high in organic matter. Common comfrey, Symphytum officinale, is a vigorous plant that can grow up to 4 feet tall. The plant spreads by rhizomes and can become invasive.
Calamint is dotted with masses of tiny flowers that attract butterflies from midsummer until frost. The small white or pale lavender blooms make a good substitute for baby's breath. Calamint is a member of the mint family, but it doesn't spread by runners, so it usually remains well behaved in the garden. However, it can self-seed and occasionally pops up elsewhere in the landscape. Grow calamint in a location with good drainage for a low-maintenance, drought-tolerant perennial with airy texture.
Angelica is a tall, hardy biennial herb with dramatic stalks that can be candied and used on cakes or cookies. The first year, the plant produces beautiful frilly green foliage. The second year, angelica sends up flower stalks and then produces seeds. The flowers and foliage make a dramatic back-of-the-border accent in perennial beds. The celery-flavor stems may be eaten raw or candied for use in baking. Use the dried root in tea. Plants might self-sow, but plant new angelica each year to ensure a constant supply. Grow it in full sun or dappled shade in rich, organic soil.
Aloe vera is an eye-catching perennial that displays lance-shape succulent leaves decorated with white spots and edged with small whitish teeth. The leaves are known for their gel-like sap often used to soothe burns and moisturize skin. Native to hot, dry regions of Africa, this herbaceous perennial prefers frost-free, sunny, well-drained sites where the night temperature never dips below 50 degrees F. Thankfully, adaptable aloe vera makes a great houseplant; use it on its own or let it add vertical interest to a container of vining houseplants, such as philodendron or ivy. Exceptionally easy to grow, aloe vera is a good choice for a new gardener.
