Chamomile is a flowering plant that has been used for thousands of years in traditional medicine and beverages. The plant belongs to the Asteraceae family, which also includes sunflowers and daisies. Two main varieties are used for tea: German chamomile (Matricaria chamomilla) and Roman chamomile (Chamaemelum nobile). German chamomile is the more common type found in tea blends and is native to Eastern Europe and Western Asia. Roman chamomile, native to Western Europe, is slightly more bitter and is often used in herbal medicine preparations.

The name "chamomile" comes from the Greek words "kamai" (on the ground) and "melon" (apple), referring to the apple-like scent of the flowers. Archaeological evidence suggests chamomile was used in ancient Egypt for mummification and in traditional Chinese medicine for over 4,000 years. The plant's popularity spread throughout Europe during the Middle Ages, where it became a staple in monastery gardens and household remedies.
German chamomile typically grows 16 to 24 inches tall with fine, feathery leaves and small daisy-like flowers. Roman chamomile is a lower-growing plant, usually 8 to 12 inches tall, with thicker foliage and slightly larger flowers. Both varieties contain similar active compounds, though in different concentrations. Research published in the Journal of Functional Foods indicates that both types contain flavonoids like apigenin and bisabolol, which contribute to their traditional uses.
When selecting chamomile for tea, understanding these varieties matters because they have slightly different growing conditions and flavor profiles. German chamomile tends to produce more flowers per plant and is easier to grow in most climates, making it the preferred choice for home gardeners. Roman chamomile has a more delicate flavor and is sometimes preferred by those sensitive to stronger herbal tastes.
Practical takeaway: If you're growing chamomile at home, German chamomile is more productive and forgiving for beginners. If you're purchasing dried chamomile, check the label to see which variety you're getting, as this affects both flavor and the concentration of beneficial compounds.
Growing chamomile in your home garden or containers is a straightforward process that requires minimal experience. Chamomile thrives in full sunlight, needing at least six hours of direct sun daily. The plant adapts well to various soil types but prefers well-draining soil with a pH between 5.8 and 7.5. If your garden soil is heavy clay, amending it with compost or sand improves drainage and plant health.

Starting from seeds is the most economical approach. In spring, after the last frost date in your area, direct sow seeds into the garden bed or containers. Chamomile seeds are tiny and should be scattered on the soil surface without covering them, as they need light to germinate. Keep the soil consistently moist but not waterlogged for the first two to three weeks. Seeds typically germinate within 7 to 14 days at temperatures between 60 and 70 degrees Fahrenheit. Seedlings emerge as delicate sprouts and develop their characteristic feathery foliage within several weeks.
Once established, chamomile is drought-tolerant and requires minimal maintenance. Space plants 12 inches apart to allow for proper air circulation. Fertilization is generally unnecessary if your soil contains organic matter, as excessive nutrients can reduce the concentration of beneficial compounds in the flowers. Chamomile plants typically begin flowering 6 to 8 weeks after germination, with peak blooming occurring in mid to late summer.
Container growing works well for chamomile, especially if you have limited space. Use a 6 to 8-inch pot with drainage holes and quality potting soil. Water when the top inch of soil feels dry. Container plants may require weekly watering during hot weather but need less frequent watering during cool seasons. According to research from the University of Vermont, chamomile grown in containers produces similar flower quality to garden-grown plants when provided adequate sunlight.
Common challenges include powdery mildew in humid conditions and root rot from overwatering. Improve air circulation by spacing plants appropriately and avoiding overhead watering. Most pests avoid chamomile due to its natural compounds, though spider mites may occasionally appear during extremely dry spells.
Practical takeaway: Start chamomile seeds directly in soil in spring for the most reliable results. Container growing is ideal if you have limited garden space or want to move plants to optimize sunlight throughout the day.
Timing your harvest correctly ensures you capture the maximum concentration of the beneficial compounds in chamomile flowers. The flowers contain the highest levels of apigenin, bisabolol, and other flavonoids when they are fully open but still fresh. Harvesting typically begins in mid to late summer when flowers are abundant. The best time to harvest is mid-morning, after dew has dried but before the afternoon heat becomes intense. This timing ensures flowers are at their peak hydration and potency.

To harvest, gently pinch or cut the flower heads just below the base of the bloom, leaving the stem and foliage on the plant for continued growth. A single chamomile plant can produce multiple flushes of flowers throughout the growing season if harvested regularly. Removing spent flowers encourages the plant to produce more blooms. During peak season, you can harvest from the same plant every few days. Collect flowers in a basket or cloth bag rather than a plastic container, which can trap moisture and cause deterioration.
The amount of dried tea you can produce from fresh flowers is significant. Approximately 2 to 3 pounds of fresh flowers yield about 1 pound of dried flowers, and a typical serving of tea requires only 1 to 2 teaspoons of dried flowers. A single mature chamomile plant can produce 50 to 100 flower heads per season, providing multiple servings of tea. If you have limited garden space, even growing two or three plants provides substantial tea production for personal use.
Check flowers carefully before harvesting. They should have fully separated petals from the yellow center disk. Flowers that are still partially closed contain lower concentrations of active compounds. Discard any flowers that show signs of damage, discoloration, or pest damage. Avoid harvesting after rain or when flowers appear wilted, as these conditions indicate reduced potency.
If you prefer to skip growing your own, purchasing high-quality dried chamomile from reputable suppliers is a viable alternative. Look for dried flowers that are vibrant in color and have a pleasant apple-like aroma. Avoid products with visible dust or that smell musty, which indicates improper storage or age.
Practical takeaway: Harvest chamomile flowers in mid-morning when they are fully open but still fresh. Regular harvesting encourages continued flower production throughout the season, maximizing your tea supply.
Proper drying preserves the beneficial compounds in chamomile and extends its shelf life significantly. There are several effective drying methods, each with advantages depending on your climate and available equipment. Air drying is the simplest method and requires no special equipment. Spread freshly harvested flowers in a single layer on a clean cloth, paper plate, or mesh screen in a warm, dry, well-ventilated area away from direct sunlight. Position them in a room with temperatures between 70 and 80 degrees Fahrenheit. Drying typically takes 5 to 10 days, depending on humidity levels and flower size.

To test if flowers are completely dry, gently squeeze a small handful. They should crumble easily and feel papery, with no moisture remaining. If flowers feel at all soft or pliable, they require additional drying time. Incomplete drying leads to mold growth and loss of potency. A dehumidifier in your drying space accelerates the process, particularly in humid climates. In very humid regions, a fan circulating air around the drying flowers helps prevent mold.
For faster drying, you can use a food dehydrator set to 95 to 105 degrees Fahrenheit. Spread flowers in a single layer on dehydrator trays and check progress every 2 to 3 hours.
