Hibiscus: brief information
These colorful plants has huge red, white or pink flowers of 6 to 12 inches in diameter and bloom from midsummer until first frost. Garden varieties may grow up to 8 feet tall if you manage to provide very moist soil all the summer.
Hardy hibiscus grows in temperate climate and tropical hibiscus demands a frost free climate. The last one is a very popular plant, it is often grown as an annual in cold climates, or grown in pots and containers that can be brought indoors for the cold period or in the winter. Both varieties do best in full sun but will tolerate light shade. Soil for your hibiscus should be damp and well-composted.
Place plants about 3 feet apart. When setting out plants place the crowns, or tops of the roots 3 to 4 inches beneath the soil. To grow a new plant from seeds, sow it early in spring; the new one-year plants will produce only a few flowers the first year, but will bloom fully during the fallowing years.
