Yellow, orange flowers - Plant Encyclopedia Results

Impatiens is one of the best known and most popular garden plants for its prolific flowers and ease in growing. It is an evergreen perennial but is often grown as an annual in nontropical climates. Most varieties form low mounds that are usually 8-24in in height with about equal spread.

Likes moist, but well drained, fertile soil.

Propagation: Seed or cuttings in warm weather.

Valued as an ornamental plant, due to its colorful and attractive flowers. The leaves are alternate, rough, hairy, heart-shaped or 3-5 lobed with serrated margins. Flowers are Hibiscus-like.

Cultivated for aromatic oil from seeds. Young leaves, shoots, and unripe seedpods are cooked as a vegetable.

Yellow floating heart can be a popular aquatic garden ornamental for outdoor water gardens.

Shrubby, semi-woody, perennial or semi-evergreen subshrub to 2m high with a 1m spread. Very unusual funny flower! The plant grows through it! Very similar to leonotis menthifolia, but leaves are large and about triangle shape. After bloom, the new growth just keeps growing up through the flower. Tolerates poor soil. A super magnet for hummingbirds and butterflies, the hummingbirds will sip for as long as ten seconds or more from one flower. Fun in cut flower arrangements too.

This small plant grows up to 2-5 feet tall and produces brilliant red and crimson-colored flowers. There are also some varieties that boast yellow and orange blooms. It is best grown in full sun and requires regular to moderate water. Sporadic pruning will promote better flowering in the spring and fall. The flowers attract butterflies and hummingbirds, making it a great addition to any ornamental garden.

Chasmanthe floribunda (Pennants) is native to South Africa and is grown in USDA zones 10-11. However, if grown in a pot in a cold region, it is best to move the containers inside during the winter season. Potted Chasmanthe needs extra care and protection during cold weather. Make sure to provide enough water and create a warm and bright environment. The plant can also be kept in a greenhouse or conservatory where temperatures don't drop too low, even during the winter months.

It's worth the effort to grow Chasmanthe, as it is a beautiful addition to any garden. Not only will its vibrant flowers add color and life, but they will also attract butterflies and hummingbirds. With the right care this South African native will bring years of joy and enjoyment.

Anagyris foetida, or the Mediterranean Stinkbush, is a large shrub that grows between 5-10 feet tall. Native to the Mediterranean region, it forms a small, oval or round shaped shrub crowned by a tightly branched dome. Bright yellow or orange flowers bloom in the spring and give way to the distinctive backward curving seed pods. When its leaves are crushed, they emit a sharp and unpleasant odor, hence the name Stinkbush.

This plant is incredibly hardy and can tolerate intense full sun and moderate watering. Once mature, the Mediterranean Stinkbush can withstand cold down to at least 30 degrees Fahrenheit for a short time and is hardy in USDA Zone 9.

In addition to its resilient properties, the Mediterranean Stinkbush has been used as an ethnomedicinal plant. It is said to have anti-inflammatory and anti-diuretic properties due to its acidic and bitter compounds. The plant can, however, be toxic and should not be consumed in any form.

When grown in a pot, the Mediterranean Stinkbush is best suited for a cold climate. It thrives in full sun and well-drained soil. Water the soil to keep it lightly moist, allowing it to dry out between waterings. Fertilizing regularly during the growing season and providing protection from extreme cold weather will help this plant thrive and reach its full size. Prune in late winter or early spring, focusing on removing dead or weak branches.

Curious plant with tuber is above ground level covered with layers of corky bark, resembling a caudex. Slow-growing. It is a very unusual succulent. Its main feature is a large, corky caudex that grows up to one meter in habitat, resembling an elephant foot (hence the popular name). The caudex looks as if it is segmented into geometric patterns (smaller plants look like tortoises) and looks dead but is actually a living tuber. A plant with a 18" caudex can be 75 years or older. The plant grows into a vine with attractive heart-shaped leaves and small yellow flowers. Culture is relatively easy. A greenhouse is great, but a windowsill with moderate to full sun works fine, as long as the plant is kept at 65F minimum. The vines may die back and regrow several times a year, depending on the particular plant and your region. Several plants in the same pot can go dormant in different times. Tuber contains saponins, originally cooked and eaten as a famine food by the Hottentots. Slow down water when the tuber is dormant. The plant is is dioecious (male and female flowers are produced on different plants). The 0.2 inches wide (4 mm), greenish-yellow flowers are insignificant. Seeds are the only way to reproduce. The seedlings caudex forms below ground and will grow much faster if left underground for a couple of years. Prefers filtered light, and the caudex must be kept in shade. Elephant Foot is a collectors item, but remarkably easy to grow. It will be with you for years with no effort. It is a wonderful conversation piece!

Growing directions (by Ed Sienkiewicz)

D. elephantipes doesnt send down deep roots, so plant in a shallow pot (I use clay bulb pots) about 1" larger than the diameter than the caudex. Potting soil should be very porous/loose so that there is easy drainage. Think about the area in which they grow natively. Remember that these plants are tropical DESERT plants. The soil should be very loose and drain very freely. Allow the soil to come up and slightly over the edge of the caudex 1/4"- 1/2" so that the edges are covered. Water well around the edges, being sure not to get water into the point from which the vine will grow (usually there some pieces of old vine in the growing area). Keep in a warm area and wait for the first shoots of the vine to appear. Water regularly from that point on. Use dilute (25 percent of normal) fertilizer with each watering. The plant should not be kept damp as with other tropical plants. Allow it to *almost* dry before watering again. The plant has natural dormancy period. That being said, however, my experience is that the plant will go dormant when *IT* wants to. If the vine begins to yellow and die back, limit the water and stop the fertilizer. If the vine dries up cease all water and move to a cool place for a couple of weeks. Return to a sunny area and wait for the vine to sprout again. NOTE: Many books will say that they are winter growers, because they are native to the southern hemisphere. In my experience they are opportunistic growers. I have had them grow in all seasons. I have had plants that went dormant for a couple of weeks and others who were dormant for months. Let the plant be your guide. You cannot force them to grow, and over watering will simply cause them to rot. The Dioscorea elephantipes caudex is similar to Dioscorea mexicana, but the individual "squares" are far more pointed/raised. Related species - Dioscorea macrostachya (Mexico).

The leaves, stems, and green unripe fruit of the Tomato plant, as a member of the plant genus Solanum, contain the poison solanine, which is toxic to humans and animals.
