Common tansy (Tanacetum vulgare) is a weed-like perennial flower that grows from rhizomatous roots and is also known as bitter buttons, cow bitter, and golden buttons. While now considered invasive in North America, at one time the plant was an important culinary herb in Europe. Given its pedigree in the European tradition, it is not surprising that tansy flowers were soon brought to the New World by American colonists and granted a position of garden prominence. From there, however, it soon naturalized into surrounding areas and is now viewed as a noxious weed over large areas of the United States.1 The name is derived from the Greek athanatos, meaning immortality, either because it is long-lived or because tansy was used for embalming in ancient times. In Greek mythology, Zeus was said to have made Ganymede immortal by giving the him tansy on Mount Olympus. Now, however, tansy has been listed by watchdog groups as one of the worst invasive plants in North America.2 Tansy can be identified by its aromatic, fern-like foliage, and bright yellow button-like flowers that appear in flat-topped clusters in summer. The leaves bear a similarity to yarrow, which is also a member of the Asteraceae family of plants. Botanical Name Tanacetum vulgare Common Names Common tansy, bitter buttons, cow bitter, golden buttons Plant Type Herbaceous perennial flowering plant Mature Size 2 to 4 feet tall, 12- to 18-inch spread Sun Exposure Full sun to part shade Soil Type Well-drained, fertile soil Soil pH 4.8 to 7.5 Bloom Time July and August Flower Color Yellow Hardiness Zones 3 to 8 (USDA) Native Area Temperate regions of Europe and Asia, naturalized over much of North America Toxicity Toxic to humans, dogs, cats, and livestock.
How to Care for Common Tansy Common tansy is a low-maintenance plant that requires very little care on the part of the gardener. Although it is considered an invasive plant, it does have its uses. When properly harvested and dried, the bright yellow button flowers produce a soft yellow dye. The plant's history as a strewing herb still bears out today as Common Tansy will repel flies and other pesky insects. Additionally, tansy flowers add potassium to soil and attract an important beneficial insect, the ladybug.2 If you're considering growing tansy flowers, make sure to clip off the spent flowers to prevent this troublesome plant from self-seeding. Keep in mind that the sale of these "noxious-weed seeds" are prohibited in Montana and Wyoming.3 The plant itself is prohibited to be sold or grown in Colorado, Minnesota, Montana, Wyoming, parts of Washington state, and the Alberta and British Columbia provinces in Canada. Light Tansy flowers grow best in full sun, though they can tolerate part shade. Soil This perennial plant prefers well-drained, fertile garden soil but tolerate almost any soil conditions. Water Tansy can tolerate drought and does not need regular watering. Temperature and Humidity Tansy flowers are winter hardy to minus-40 degrees Fahrenheit. The leaves will turn brown, curl, and dry up in extreme prolonged heat.4 Pruning Common Tansy One of the best methods for keeping tansy under control is deadheading the flowers. Cut the foliage and flower stems to the ground every year to keep growth in check. Tansy roots go deep so be prepared to do some heavy shovel lifting if you want to remove the plant completely. You can also try spot spraying with a broad spectrum weed killer. Always use caution, and wear protective clothing, gloves and goggles, when using chemical herbicides.
Common Tansy vs. Tansy Ragwort Do not confuse this plant with "tansy ragwort" (Senecio jacobea), which is a different plant altogether. Tansy ragwort is a winter annual, biennial or short-lived perennial that is also considered a noxious weed. Common Pests and Plant Diseases Since the heavily scented leaves of common tansy act as insect repellent, the plant is not vulnerable to pests or disease. Unfortunately, unless measures are undertaken to control its spread, the plant itself could turn out to be the biggest problem.

Rue is a short-lived perennial herb with a small, shrub-like growth habit. It features aromatic, blue-green foliage with a fern-like appearance. And in the summertime, it sports clusters of small yellow flowers that attract butterflies and other pollinators to the garden, as well as parasitic wasps. The ornamental herb has a moderate growth rate and should be planted in the spring after danger of frost has passed. Be aware that despite their past as a traditional use as a medicinal herb, rue leaves are toxic both to people1 and pets2. Common Name Rue, common rue, garden rue, herb of grace Botanical Name Ruta graveolens Family Rutaceae Plant Type Perennial, herb Size 2–3 feet tall and wide Sun Exposure Full sun Soil Type Well-drained Soil pH Acidic, neutral, alkaline (6.5 to 8.5) Bloom Time Summer Hardiness Zones 4–10 (USDA) Native Area Europe Toxicity Toxic to people, toxic to pets How to Plant Rue When to Plant Rue is normally planted from potted nursery starts or from seeds in the garden once spring soil temperatures reach around 70 degrees Fahrenheit. Seeds will germinate in one to four weeks.
Selecting a Planting Site If you choose a sunny site with good drainage for your rue plants, they almost certainly will thrive with virtually no care. Rue flowers are good candidates for tough sites and will even grow in gravel. If your garden has heavy or wet soil, consider container culture. Avoid putting the plants near walkways or other areas where you might come in contact with them, as the sap can cause skin irritation.3 Spacing, Depth, and Support Smooth the soil of your garden site prior to planting, and break up any soil clumps. Then, simply scatter the seeds over the moist soil surface and slightly press them in, as they need light to germinate. Space plants around 1 to 2 feet apart. Do not allow seedlings to dry out. A support structure typically won’t be necessary, as rue naturally has an upright growth habit. Rue Plant Care Light Rue grows best in full sun, meaning at least six hours of direct sunlight on most days. But partial shade is also tolerated. However, plants will produce fewer flowers in the shade. Soil Sharp drainage is important for healthy rue plants. Add sand, perlite, or vermiculite to the soil to help drainage. Or use raised beds with prepared soil in gardens where heavy clay dominates. Rue likes a moderately rich soil but can tolerate poor soils. And it can grow in a slightly acidic to slightly alkaline soil pH. Water Once established, common rue is very drought tolerant and is a good candidate for a xeriscape or rock garden. You won't need to water except for periods of extensive dry weather. Avoid overwatering, which can cause root rot. Temperature and Humidity Rue plants thrive in hot weather and low humidity, similar to their native habitat of Greece, Turkey, and Italy. However, the plants are tolerant of humidity as long as they have good soil drainage and air circulation around them. Fertilizer Do not fertilize rue plants. Excess nutrients will cause the plants to produce more foliage at the expense of the flowers. Pollination Garden pollinators, including bees and butterflies, are highly attracted to rue and assist it in its pollination. Types of Rue There are several varieties of rue, including: ‘Blue Beauty’: This plant has especially vivid blue-green leaves. ‘Jackman’s Blue’: This variety features a strong blue color and a potent aroma. ‘Variegata’: The leaves on this variety have some white in them. Rue vs. Fenugreek As another bitter herb that bears small yellow flowers, it's easy to confuse fenugreek (Trigonella foenum-graecum) with rue. Fenugreek, however, is an annual legume and does not have some of the toxic properties that rue flowers do. You can grow fenugreek in the sunny garden after all danger of frost has passed and use the ground seeds in curries or the leaves in salads. Harvesting Rue Rue is often harvested to use as dried flowers. And some people make sachets out of rue and use them to deter pests, including fleas and ants. Wear gloves and long sleeves when working with rue to protect your skin. Cut a mature plant at ground level with pruners. Then, hang it in a dark, dry place to dry until the leaves become brittle. Keep the fully dried rue in an airtight container until you’re ready to use it for sachets or other purposes. How to Grow Rue in Pots If you don’t have garden space or have heavy soil, container growth is a good option for rue. Choose a pot that’s around 12 to 16 inches wide and deep, and make sure it has drainage holes. An unglazed clay container is ideal because it will allow excess soil moisture to escape through its walls. Pruning Rue is a semi-woody perennial that flowers on new growth. To keep the plant vigorous and looking its best, cut stems back to around 6 inches in the early spring. Don’t wait too long, or you’ll end up pruning off some flower buds. You also can prune in the fall after flowering is finished. Propagating Rue It's easy to make new rue plants via stem cuttings. This is a quick and inexpensive way to replace mature plants that are nearing the end of their life cycle, as rue plants only live around five years. The best time to take cuttings is in the late summer from new growth, but be sure to wear protective clothing during the process. Here's how: Cut roughly a 6-inch piece of stem from new growth. Remove any foliage on the lower half of the cutting. Plant the cutting in a container of moistened soilless potting mix. Place in a clear bag to maintain moisture. Keep the mix moist but not soggy. Once you feel resistance when you gently tug on the stem, you'll know roots have developed. How to Grow Rue From Seed Rue is easy to start from seeds in the garden or in trays. The soil must be at least 68 degrees Fahrenheit for germination, and some light must reach the seeds. When the seedlings develop at least two sets of true leaves, they can be transplanted into larger pots. Harden off seedlings before planting in the garden. Rue plants will self-seed, sometimes aggressively, in warm regions. You can collect the brown seed capsules in late summer after flowering to plant elsewhere. Potting and Repotting Rue You can use any well-draining potting mix for rue in containers. Repotting is necessary when you see roots coming out of the drainage holes of the pot. Remember to wear protective clothing when repotting. The bluish foliage of rue plants marries well with plants that have golden foliage, such as the gold cultivars of oregano, sage, or thyme. These herbs all like the same sunny, dry conditions and well-drained soil that rue thrives in, so they blend well in mixed containers. Overwintering In the northern portion of rue’s growing zones, add a layer of mulch around the plants to protect them over the winter. Aim to do this before frost hits in the fall. Common Pests and Plant Diseases Rue doesn’t have any major pest or disease issues. In fact, if you see caterpillars feeding on your rue plants, don't spray them. It's likely they are swallowtail butterfly caterpillars, which use rue as a host plant and benefit your entire garden. The primary disease issue that can affect rue is root rot from wet soils. So ensure that your plants are never waterlogged.
FAQ Is rue easy to grow? Rue requires very little maintenance as long as it has a sunny spot with well-draining soil. How long does it take to grow rue? Rue has a moderate growth rate and will germinate in one to four weeks. Does rue come back every year? Rue is a perennial, coming back every year, but it doesn't tend to be long-lived. However, it will self-seed to produce new plants in the garden.
