With oversized, tropical-looking leaves and bizarre seed pods, castor bean is an exotic addition to the ornamental garden. The only member of the genus, Ricinus communis is in the Spurge Family (Euphorbiaceae). The name of this plant comes from the Latin word for “tick,” which was used because the seeds look a bit like a certain species of European tick. Castor bean comes from tropical east Africa, around Ethiopia. It has spread to become a weed in many tropical and subtropical places around the world, including the southwestern U.S. S. Most plants grow in disturbed areas with moist, well-drained soils, like along riverbeds and roadside, as well as in fallow fields and on the edges of cultivated lands. Castor bean is an evergreen herbaceous or semi-woody large shrub or small tree. This tough, tender perennial can grow up to 40 feet tall. In places that don’t get frost, the stems will turn woody after a few years. It is easy to grow as a warm season annual in mild climates because it grows quickly and strongly, but it rarely gets taller than 6 to 10 feet in a single growing season. At first, this fast-growing plant tends to grow straight up. Later in the season, it will add branches to form a well-shaped shrub with strong stems and a dense canopy. The plant is killed when the temperature drops below 32F. This plant doesn’t have milky latex sap like many others in the euphorbia family. Instead, it has a watery sap. The alternate, star-shaped leaves on long petioles can grow over 2½ feet across. Each palmate leaf has 5 to11 deeply incised lobes, with serrated edges and prominent central veins. While the species’ leaves are glossy and green, cultivated types may have leaves that are black-purple, dark red-metallic, bronze-green, maroon, or bright green with white veins. Flowers are produced in dense inflorescences 8-18″ tall at the tops of the stems. The monoecious plants produce male flowers below the terminal female flowers. The flowers do not have petals and are not particularly showy. Each ½-inch male flower has a group of many cream or yellow stamens that spray a lot of pollen into the air. They senesce soon after shedding their pollen. The three conspicuous, star-shaped stigma lobes of the female flowers are bright red with feathery branches. Once the flower is pollinated, its small, spiny ovary turns into a fruit or seed capsule about the size of a golf ball. The seed pods may be green, pink, or red (depending on the variety), but gradually age to brown. Each round seed capsule has a lot of soft, flexible spines all over it, and it has three parts that separate when the seeds are ready. Each section contains one seed that is ejected, often with considerable force, when the carpel splits open. If the growing season is long enough (140 to 180 days), a lot of the ½-inch long seeds, which are sometimes called “beans” but aren’t really beans, are made. The shiny, mottled seeds are very pretty. They come in black, gray, brown, yellow-brown, maroon, and white, and each has its own design. Each seed has a small, spongy caruncle at one end which helps absorb water for germination when planted. Seeds remain viable for 2-3 years. Heavy oil, yellow or almost colorless, makes up about half of the seed’s weight. This oil has been used in many industrial settings. In the past, the oil was used to light lamps. Today, it is used to make paints and varnishes, water-resistant coatings, high-performance motor oils, soap, inks, and plastics. Other derivatives are used in polishes, as solid lubricants, in synthetic perfumes and other products. Plants are grown commercially in India, Brazil, and some parts of the United States to make oil. S. and other countries. Plants should be kept out of reach of children because the seeds are very poisonous. If you are worried about this, you can cut off the flowering spike. Ricinol, which is found in castor seeds, is one of the most poisonous natural substances. It is thought to be 6,000 times more poisonous than cyanide and 12,000 times more poisonous than rattlesnake venom. A normal-sized adult can die from eating as few as four seeds. Eating less will make them vomit, have severe abdominal pain, diarrhea, and seizures. Livestock and poultry can also be affected if they consume seeds or meal from the seeds. Although it is a very potent poison, ricin has been investigated as an anti-cancer agent. The ricin chemical dissolves in water but not in lipids (oils), so it stays in the “seed cake” after pressing. This waste is turned into a high-nitrogen fertilizer, or the meal can be fed to animals after being cleaned of its chemicals. Castor oil can be eaten and has been used medically to treat everything from heartburn to constipation because the toxin is not in the pure oil. It works well as a laxative or cathartic, and it can also be used on the skin to soothe dryness. Castor bean can be planted directly in the garden in late spring if it is grown for its looks, or it can be started indoors earlier (6–8 weeks before the average last frost) and moved outside when the weather gets warmer. Nick or scarify the seeds or soak overnight for better germination. Sow the seeds 1-1½ inches deep. Seedlings should start coming up in 1-3 weeks. The young plants grow quite quickly and may need repotting into larger containers before transplanting outdoors. Place the plants outdoors in full sun and deep, rich soil about 4 feet apart. Provide plenty of water and fertilizer to achieve the largest size. Once established it can tolerate drought. Wind can shred the leaves, so they should be placed in a protected spot if possible. This plant doesn’t need much care besides being pruned to keep it from getting too big or staked if it’s too heavy at the top. Castor bean has few pests, although spider mites can sometimes be a problem in hot, dry weather. With its large leaves and tall stature, castor bean makes a bold statement in the garden. The coarse texture contrasts well with finely textured plants. Castor bean can be grown as a single plant to make a dramatic focal point in the landscape, or it can be grown in groups for a tropical look in the back of beds or near water features. You can grow it in big pots on patios or use it to make a temporary screen or privacy fence. Castor bean combines well with cannas, bananas and elephant ears for a tropical garden. Or use it as a backdrop for grasses and other large-scaled annuals for a more traditional look. A range of varieties have been selected for their leaf or flower/fruit colors, and for oil production. Some of the most common ornamental types include:
Castor bean plants, also known as Ricinus communis, are quite fascinating Their large, vibrantly colored leaves and spiky seed pods make them visually interesting. As an avid gardener and nature lover, I’m always on the hunt for eye-catching photos of plants to reference in my landscaping projects or just to admire their beauty

Overview of the Castor Bean Plant
First, a quick overview of what exactly the castor bean plant is. Ricinus communis is a fast-growing perennial that can reach up to 15 feet tall in ideal conditions. Its large palmate leaves can be green, bronze, or reddish-purple depending on the variety.
The flowers are actually quite subtle, with the female flowers just pale green spikes. But the real showstopper is the fruit – spiky seed capsules that turn from green to red as they mature. Inside the capsule are the actual castor beans, which is where castor oil derives from.
While the beans are very poisonous to humans, the plants are commonly grown ornamentally for their tropical, exotic look. Their visually striking leaves and seed pods make the castor bean plant a favorite for photographers.

Sharp focus – Look for images with tack-sharp focus, especially on the details of the leaves and seed capsules. The intricate shapes should be clearly defined.
-
Good lighting – Images with bright, even lighting that showcases the colors and textures of the plant are ideal. Front or backlighting that illuminates the foliage is great.
-
Composition – How the castor plant is framed in the photo is key. Look for rule of thirds positioning and angles that highlight the visual appeal of the leaves and fruits.
-
Background – A blurred or plain background helps the vibrant castor bean stand out. Busy backgrounds are distracting.

Color – The photo should capture the vivid greens and reds of the plant. Images edited to be too saturated or contrasty look artificial.
