Their wide petals, elaborate centers, and vivid colors attract attention—and hummingbirds. Hibiscus is not subtle in the slightest, which is presumably why so many people adore these blooms. What you should know about caring for hibiscus both indoors and out is provided here.


Hibiscus Varieties

Hibiscus is a mallow. Several hundred species of Hibiscus, including the rose of Sharon, are endemic to tropical and temperate climates.

Most people associate hibiscus with Hibiscus rosa-sinensis, grown in tropical locations worldwide but native to Asia. Many cultivars of this hibiscus have magnificent hues and color blends, some with double flowers, and new types are always appearing to gather and grow.

Try Monrovia’s Jazzy Jewel Hibiscus. Hot climate gardens get tropical with long-lasting blooms. Grow these frost-tender jewels in a big pot on a patio in cooler climates. Jazzy Jewel Ruby’s enormous red blossoms and tasty reward attract hummingbirds. Also, butterflies may visit these flowers. Watch for Jazzy Jewel Opal, Gold, and Amber.

Hibiscus Care Outdoors

Hibiscus needs lots of sun and space to grow. Once grown in zones 9–11, hibiscus is drought-tolerant but may flower less during dry spells. Plant it in well-draining soil and prune once or twice a year. Hibiscus flowers on new growth, so don’t prune too often.

Cover your outdoor hibiscus with a sheet or frost cloth for a few days.

Hibiscus Insect Pests

Hibiscus can be bothered occasionally by white fly or aphids. Remove these pests with a hard blast from your garden hose, or spray with an insecticidal oil.

Coppery green Japanese beetles also feed on hibiscus. Knock them into a can of soapy water or use a small hand-held vacuum to remove them.


Hibiscus Care Indoors

Being a tropical plant, Hibiscus rosa-sinensis cannot withstand frigid conditions. However, this does not imply that only those in Florida and California may produce hibiscus. Planting hibiscus outdoors during the summer and bringing them inside when the weather cools off works wonders for this plant. (Psst: here’s how to determine the dates of your first and last frost).

Since hibiscus is a shrub, it can become unmanageable in small areas. Trim it as necessary. Fertilize your indoor hibiscus plants about once a month.

In the winter, don’t count on seeing many blooms. Still, if these plants receive enough intense sunlight, they can blossom all year long. It’s quite exciting to see a huge hibiscus blossom indoors when the outside is completely blanketed in snow. For optimal flowering, keep the soil damp but not soggy.
