Are celosia annuals or perennials?
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.
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.
- Kong coleus (Solenostemon scutellarioides "Kong Series") is a group of shade-loving plants with leaves large enough to cover a human face. Mostly grown outdoors as an annual plant or indoors as a potted plant, Kong coleus can survive winter outdoors in U.S. Department of Agriculture plant hardiness zones 10 through 11.
- A tender perennial is defined as a perennial, a plant that can live for many years, that is not winter hardy (will die in winter in one's parRcular climate). SomeRmes these plants are called annuals for the sake of simplicity, but they are not true annuals, which cannot be live more than one year.
- 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.
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.
- Being a lush foliage plant, coleus is not resistant to rabbits, but a particular species, referred to as coleus canina (Plectranthus caninus), does deter rabbits. Coleus canina is hardy in USDA zones 9 through 11.
- Morning sun (and a little afternoon shade) is perfect. Wax begonias can tolerate more sun than other types, and the ones with bronze-colored leaves are the most sun-tolerant of all. Tuberous begonias prefer more shade and less heat, so we often see them on display in late summer. Soil: Light, rich, humusy soil.

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.
- Light for Caladiums: All caladiums love filtered sunlight and shade. Some newer selections can take more sun. Best Soil for Caladiums: Caladiums need well-drained soil that's rich in organic matter, such as mushroom compost or chopped leaves. Keep the soil slightly moist.
- In U.S. Department of Agriculture plant hardiness zones 9 through 11, caladium tubers are left in the ground over the winter, to grow back in the spring. Caladiums are grown in other USDA zones around the country where they are treated as annuals.
- Plant zinnias in mixed plantings with other summer-blooming annuals, or place small groups of zinnias among perennials. They are at home in cottage and children's gardens, and they are often grown in cutting gardens. Shorter zinnia varieties are ideal for containers.
