Coleus, made popular as Victorian-era bedding plants, have made a huge comeback thanks to the all-season color the lovely foliage offers, whether it's planted in full sun or shade. Coleus plants are characterized by square stems and leaves situated directly opposite one another. Though it produces tiny blue to white flowers, they are insignificant and are often pinched off to conserve the plant's energy. The foliage can vary widely in shape, style, and color. Breeders regularly produce new introductions with even more unusual colors and patterns. Planted outdoors in early spring, coleus quickly grows to full size in a single season. Large swaths of assorted coleus plantings that take on a quilt-like appearance can look luscious in a landscape or garden beds. Its vividly colored foliage also adds a decorative touch to window boxes, outdoor container gardens, and hanging baskets. Coleus is toxic to pets.1
Common Name Coleus Botanical Name Plectranthus scutellarioides Family Lamiaceae Plant Type Herbacious perennial (usually grown as an annual) Mature Size 6-36 in. tall and wide Sun Exposure Part shade to full shade Soil Type Rich, moist, loose soil, well-drained Soil pH Slightly acidic to neutral (6.0 to 7.0) Bloom Time Seasonal Flower Color Blue to white Hardiness Zones 10-11 (USDA); grown as an annual everywhere Native Area Asia Toxicity Toxic to animals Coleus Care Coleus is a tender tropical plant, native to areas bordering the equator. Warmer zones can grow coleus as garden perennials, where they can grow to resemble small shrubs with thick woody stems. Though it loves the heat, it will happily grow as an annual in just about any garden, where it's normally used as an annual bedding plant or in containers. However, coleus plants are not at all frost-tolerant, so don’t rush to get your plants in the ground. Wait until temperatures remain reliably above 60 degrees Fahrenheit before you move them out in the garden. They will do best in rich, loose, well-drained soil, so amending with compost or adding perlite to soil before planting is advised unless you have very good soil. Light Coleus is a classic part-shade to full-shade plant, but light exposure depends on the variety. The old-fashioned seed-grown coleus does best in part shade to full shade, but newer cultivars, like the Wizard series, perform well in full sun. Too much sun can scorch leaves and cause color to fade in most classic coleus varieties. Coleus performs best with filtered morning sun and shade in the afternoon, especially in hot climates. Plants grown in containers indoors usually get plenty of light from indirect sun during the warmer (brighter) months but may need to be exposed to filtered sunlight during the winter. It doesn't take much, but they do need some light. Soil Coleus prefers consistently moist, rich, well-draining soil. Before planting, amend the soil with compost or another organic material. For potted plants, any good-quality potting mix will work fine. Make sure to choose a container with drainage holes. Container-grown coleus loves the loose texture of potting soil, and it always helps to start with a quality mix with a slightly acidic to neutral pH of 6.0 to 7.0. Provide drainage in the pot to ensure the soil isn't constantly wet, which can lead to root rot. Water Coleus plants grow best in soil that is consistently moist but not soggy. The soil should not remain wet all the time, but long dry spells will slow the plants’ growth, and the leaves will start to turn brown around the edges. Let the soil dry out a bit between waterings, and water when the top inch of soil feels dry to the touch. Mulch will help the soil retain moisture longer, but don't use cedar mulch, which can be toxic to coleus. Also, don't let the mulch touch the stems, as it can promote rot and hide slugs. Coleus in containers may need watering twice a day during hot weather. Outdoor containers may require water twice a day. Indoor plants need water only when the top inch of soil feels dry to the touch. Temperature and Humidity As a tropical plant, coleus thrives in hot, humid conditions. In temperate climates, the barest hint of frost will spell the end of the plants. Move plants indoors or protect them on chilly nights when temperatures dip into the 50s. Make sure to take cuttings for propagation before the weather turns cold. Keep indoor plants away from air conditioner vents and other cold spots. In dry climates, the plants will like some humidity from a humidifier or a bathroom environment. To take potted plants outdoors in spring, wait until the temperature is 70 degrees Fahrenheit or warmer. Fertilizer If you have rich soil, you may not need to feed coleus plants at all. If you have poor soil, add a balanced slow-release fertilizer in the bed. You’ll get the best color from your coleus leaves if you go easy on the fertilizer. Feed container-grown plants once a month with a water-soluble fertilizer. Container plants generally need more feeding than garden plants because frequent watering washes nutrients from the potting soil. Types of Coleus There are hundreds of coleus cultivars available with various colors, leaf textures, and patterns. Additional cultivars are developed each year, and garden centers tend to focus on a select few that have proven to be most popular among their customers. You may have to shop several different nurseries or online retailers to find the most unique varieties. Some types to look for include: Wizard series: These are small 12- to 14-inch plants in standard color mixes. They are known to be very easy to grow from seeds. Kong series: These coleus varieties have huge 6-inch leaves on big 2-foot tall plants. They are quite sensitive to direct sunlight. 'Black Dragon': This unusual variety has deep burgundy leaves with ruffled edges. They grow to 18 inches tall. Premium Sun series: These cultivars are bred to tolerate full sun. Fairway series: These are dwarf coleus varieties, only 6 to 10 inches tall, in a variety of leaf patterns and colors. Pruning To get full, bushy plants, pinch out the growing tips when the plants are about 6 inches tall. Pinch under the flower buds if you want the plant to spend its energy on leaves and not flowers and seeds. Plants that are not pruned tend to get leggy and lose their nice shape and dense foliage. If they remain leggy, the plants may need more sun. This is most common with indoor plants during winter so give them a bit more sun or, if necessary, artificial light. Propagating Coleus Favorite coleus plants can easily be propagated by taking stem cuttings and rooting them. With a sharp shearing scissor, cut a 4- to 6-inch long stem tip. Make sure to cut right beneath a leaf node along the stem. Remove all leaves from the lower half of the cutting. Dip the end of the stem in a rooting hormone compound, then plant it in a moist potting mix so the soil covers the exposed leaf nodes. Place the container in a plastic bag, making sure the plastic doesn't touch the cutting. Place the covered cutting in a bright, warm location until new roots develop, which will take two to three weeks. Remove the plastic and continue to grow the new plant in a bright, warm location. Some of the more unusual cultivars might be reluctant to root, so with these, take plenty of cuttings to ensure that you get enough viable plants. How to Grow Coleus From Seed Modern coleus varieties sold in stores are hybrids that are almost always grown from cuttings potted up for nursery sale, but you can still find seeds of many varieties. If you will be planting the coleus in the outdoor garden, start seeds indoors about eight to 10 weeks before your last frost date. It's easy to grow coleus from seed. It can take as long as 21 days for the seeds to germinate, so be patient. Once seedlings appear, it will take three or four weeks of warm weather to help turn them into fully grown plants. Lightly sprinkle the tiny seeds over a tray filled with potting mix, then lightly cover with a sprinkling of soil. Cover the tray with plastic and set it in a bright, warm spot until seedlings sprout, which takes about two weeks. Remove the plastic and continue to grow the seedlings while keeping the soil moist. When two sets of true leaves appear on the seedlings, carefully transplant them into their own pots and continue growing them until outdoor planting time. Make sure to harden off seedlings before planting in the garden. Potting and Repotting Coleus To grow coleus in a container, start with a large pot that the plant can grow into, otherwise, you'll be repotting this fast-growing plant before you know it.
In mixed container plantings, coleus usually serves as an upright "thriller" plant in the center of the container, surrounded by "fillers" and "spillers." In colder zones, container plants are sometimes moved indoors to overwinter. Common Pests & Plant Diseases Groundhogs and young rabbits love coleus. If you can protect your plants early in the season, these pests will usually turn their attention to other plants by mid-summer. Watch out for mealybugs, aphids, spider mites, whiteflies, and slugs. Coleus is not usually bothered by diseases unless the weather turns cool and damp. If that happens, expect to see signs of fungal diseases, such as mildew. Be careful that the plant enjoys good drainage, because standing water can lead to fungal root rot and stem rot. FAQ Is coleus easy to care for? Coleus is very easy to care for. If you plant coleus in containers, you may want to bring it indoors during the winter to help it survive. How fast does coleus grow? Coleus quickly grows to full size, potentially up to 36 inches high, in a single season. Can coleus be grown indoors? Coleus makes a good container plant that can even be grown indoors.

The coffee plant is an attractive little specimen with glossy green leaves and a compact growth habit. It makes a surprisingly good potted indoor plant. Native to Ethiopia, the coffee plant (Coffea arabica) will flower in the spring with small white flowers and then bear half-inch berries that gradually darken from green to blackish pods. Each of these fruits contains two seeds, which eventually become the coffee beans you use to brew coffee. Other than the seeds, it's important to know that all plant parts are toxic to both humans and animals.12 In their native habitat, coffee plants grow into medium-sized trees. But growers regularly prune the plants to be a more manageable size, especially when the plants are grown indoors. (Note that you can't grow coffee plants from the beans you buy in a store; those have been treated and roasted and will not sprout.) Even though coffee plants are vigorous growers, it will typically take a few years before your plant produces flowers and subsequent fruits. All parts of the plant are toxic to pets and humans—the beans are edible to humans. Common Name Coffee plant, Arabian coffee Botanical Name Coffea arabica Family Rubiaceae, Madder Plant Type Evergreen perennial Mature Size 6–15 ft. tall and wide Sun Exposure Bright, indirect light Soil Type Rich and moist Soil pH 6.0-6.5 (slightly acidic) Bloom Time Spring Flower Color White Hardiness Zones 9–11 (USDA) Native Area Ethiopia, tropical Africa Toxicity All parts of the plant are toxic to dogs, cats, and people; beans are edible for people
Coffee Plant Care The best environment in which to grow coffee plants is to mimic its natural conditions found on a tropical, mid-elevation mountainside: plenty of water with good drainage, high humidity, relatively cool temperatures, and rich, slightly acidic soil. You can grow coffee plants outdoors if the conditions are similar to their natural environment. Indoors, coffee plants do best placed near a window but not in direct sunlight. Make sure to keep the plant away from drafts, such as those produced from air conditioning. Be prepared to water at least weekly to keep the soil moist. Light Coffee plants prefer dappled sunlight or full sunlight in weaker latitudes. They are actually understory plants (existing under the forest canopy) and do not thrive in direct, harsh sunlight. Coffee plants that are exposed to too much direct sunlight will develop leaf browning. Soil Plant coffee plants in a rich, peat-based potting soil with excellent drainage. Coffee plants prefer acidic soil, so if your plant is not thriving add organic matter such as sphagnum peat moss to increase soil pH. The ideal pH range is closer to 6 to 6.5. Water These plants are water lovers and require both regular and ample watering. The soil should stay evenly moist but not waterlogged. Never allow the soil to dry out completely.3 Temperature and Humidity The optimal average temperature range for coffee plants is a daytime temperature between 70 to 80 degrees and a nighttime temperature between 65 to 70 degrees. Higher (hotter) temperatures can accelerate growth, but higher temperatures are not ideal for growing plants for their beans. The fruits need to ripen at a slow, steady pace. In addition, because these plants naturally grow on the sides of tropical mountains, they thrive in highly humid conditions which usually receive plenty of rain and fog. A humidity level of 50 percent or higher should suffice. If the air is too dry, the leaf edges might start to brown. Mist the plant daily to raise the humidity level. Fertilizer Feed with a weak liquid fertilizer throughout the growing season every couple of weeks. Cut the fertilizer back to once a month or so in the winter. Types of Coffee Plant Coffea arabica 'Nana': This is a dwarf variety that only grows 12-inches tall, making it ideal to cultivate indoors. Coffea canephora: Commonly known as robusta coffee, this species comes from sub-Saharan Africa. Its plants are robust; however, the coffee beans are less favored because they tend to have a stronger, harsher taste than arabica beans. Coffea liberica: A variety native to central and western Africa, it was first discovered in Liberia. It produces large fruits with a higher caffeine content than arabica beans, but lower than robusta beans. Pruning Coffee plant needs little pruning, but should be cut back in the spring with clean, sharp gardening shears. This will help shape your plant, and it will grow back bushier! Propagating Coffee Plants To propagate coffee plant, you can do so from cuttings or air layers (a somewhat involved technique where you root branches still attached to the parent plant). The best time to take a cutting is in the early summer. Select a straight shoot that's about 8 to 10 inches long and remove all but a pair of upper leaves. Then, plant the cutting in a small pot of soilless potting mix, and keep the soil slightly moist. When you can gently tug on the plant and feel resistance, you'll know roots have formed. How to Grow Coffee Plant From Seed While you can't germinate the coffee beans you buy in a store, you can sprout the ones that grow on your coffee plant. Called "cherries," rub away their flesh wash away any residue; dry thoroughly by sitting in the open air for a few weeks. Then, soak the cherries in water for 24 hours, and then sow in damp, but well-draining, sand. If you water daily, the cherries should germinate in two to four months. When they've germinated, carefully remove them and plant each one in well-draining, acidic soil. Water twice a week. Potting and Repotting Coffee Plant Repot your coffee plant every spring, gradually stepping up the pot size. Make sure the container has several drainage holes. If you want, you can prune the plant to the desired size, slightly restrict its pot size, and root prune to keep its growth manageable. Common Pests & Plant Diseases Coffee plants grown indoors will sometimes suffer from infestations of mealybugs, aphids, and mites.3 Signs of infestation include tiny webs, clumps of white powdery residue, or visible insects on the plant. Treat infestations with insecticides, or something organic like neem oil. as soon as possible to prevent them from spreading to the rest of your collection. How to Get Coffee Plant to Bloom Coffee plants bloom delicate, white flowers, once the plant is around three-years-old. If these blooms are pollinated—if your coffee plant is outdoors—the flowers will give way to little, red fruit (the "cherries") that are slightly soft to the touch. To get your own coffee plant to bloom, make sure it's at the right temperature—70 to 80 degrees Fahrenheit during the day—has four to five hours of sunlight a day, and is growing in damp, well-draining soil. Common Problems With Coffee Plant Brown spots on leaves Fungal diseases like leaf spot can give your coffee plant brown spots on its leaves. To remedy, remove affected leaves and stems and trim away inner branches so there is better air circulation for your plant. Brown leaves that fall off Leaves that turn brown and fall off usually do so from leaf scorch (otherwise known as "too much sun"). Fixing the former is merely a matter of giving your coffee plant more indirect light.
FAQ Is coffee plant easy to care for? Yes! Coffee plant is a super easy plant to grow. With the right light, water, and humidity, it's a welcome addition to your home. How fast does coffee plant grow? Coffee plant takes three to five years to reach maturity. Can coffee plant grow indoors? Absolutely! While when planted outdoors a coffee plant can reach 6-feet tall, most indoor growers prune them so they stay within a manageable size of 1 to 2 feet.
