Can coleus survive the winter?
A coleus plant is hardy, able to survive in both a container indoors and in the soil outside. However, being a warm weather loving plant, it will not survive a harsh, cold winter. When the weather begins to turn cold you will need to take some precautions to ensure a healthy coleus in the spring.
Conditions: Coleus are tender tropicals that are generally grown as annuals because they are hardy only in USDA Hardiness Zone 11. They like warm soils with decent drainage. They are not happy in overly dry conditions. Coleus will grow in full sun to medium shade, but their colors are most vivid in full sun.
- Coleus likes bright light, but be careful of intense sunlight. If you enjoy growing coleus plants indoors, you can always start new plants with 2-inch cuttings taken from a healthy, mature plant. Plant cuttings in moist potting soil, then keep them moist and warm until the new plants are established.
- Foliage Plants Plants. When people think of coleus, they may think of a drab little shade plant that their grandmother grew, says garden writer and coleus connoisseur Steve Silk. But coleus has surged in popularity, due in large part to new cultivars that grow — and thrive — in full sun.
- Plant impatiens transplants after the last spring frost.
- Impatiens prefer humus-rich, moist, and well-drained soil.
- The closer impatiens plants are, the taller they will grow, so space accordingly (impatiens plants can grown anywhere between 6 and 30 inches tall).
Coleus plants are members of the Mint family! There are over 3,500 members of this big, big plant family. These tender annuals can be grown from seed or cuttings. They like sunshine, but tolerate shade very well, making them a great indoor houseplant.
- Zinnias are undemanding annuals that simply need full sun, warmth, and well-drained soil rich in organic matter. If soil is poor, incorporate lots of compost or leaf mold. Zinnias can be direct sown or transplanted into the garden. Space taller varieties about 12 to 18 inches apart.
- Not all poppies are perennials. A poppy can be any member of the genus Papaver, which contains about 70 species of annuals, perennials and biennial plants. All are native to temperate zones of the world. Most have four petals, often crinkled, resembling tissue paper or pleated fabric.
- Irrigation for Regular Maintenance. Zinnias can withstand moderately dry soil conditions but do better with supplemental watering. In general, zinnias typically need 1 inch of water once every five to seven days. However, check soil moisture depth to ensure you're providing enough irrigation.
Celosias are one of the most eye-catching annuals to grow in the garden. Technically speaking, however, they are tender annuals, as they are perennial in Zones 10 to 12.
- Although celosia is primarily grown as an ornamental plant in the U.S. it is a commonly grown vegetable throughout Africa. The leaves, tender stems and even young flowers are combined with other vegetables in soups and stews. Celosia leaves can be boiled or steamed and eaten as a side dish as well.
- This tough plant blooms all summer long. While all varieties are beautiful, keep an eye out for the sweetly scented selections. While most gardeners treat angelonia as an annual, it is a tough perennial in Zones 9-10. Or, if you have a bright, sunny spot indoors, you can keep it flowering all winter.
- Most plants that we call “annuals” are actually tender perennials that can't survive winters in colder climates. We treat them like annuals, cast them on the compost heap in the fall and buy new ones the following spring. Last summer I purchased a lantana at our local garden center.
