The Hibiscus genus comprises more than 200 different species. Hibiscus species are found in tropical and subtropical regions, as well as in temperate climates. It is a broad genus that contains herbaceous plants, shrubs and even small trees.
Hibiscus plants are popular in gardens and flower arrangements, since the plants produce astonishingly beautiful flowers on a tall stem. You can choose between wide range of different Hibiscus colors, including the popular red, pink, orange, violet, lavender, yellow and white variants. A Hibiscus flower can reach a size of 4-15 centimeters across and is equipped with five petals. Hibiscus leaves are toothed or lobed and have a deep green shade.
Hibiscus plants will require quite a lot of light, and a majority of the Hibiscus species origins from warm regions of the world. Most Hibiscus species will prefer to be planted where the temperature ranges from 60 to 90 degrees F during most parts of the day. These plants are tougher than many other tropical and subtropical species and will usually survive quite low temperatures as long as they are not prolonged. A cold night can for instance make the plant shed its leaves and buds, but it will survive and eventually begin to form new leaves and buds. You can keep a Hibiscus plant in areas where the temperatures drop below 50 degrees F, but these Hibiscuses will rarely flower. When it does flower, the blossoms will typically be very small and sometimes look a little weird. In a cold climate, you should not give your Hibiscus too much water since this will increase the risk of fungal infections. Temperatures below the freezing point should always be avoided.
If you take care of your Hibiscus, it will begin to produce buds. Hibiscus buds are typically big and tight. Unfortunately, Hibiscus buds are often attacked by worms and insects that can kill the entire bud. When the buds open up and begin to blossom, you can protect them from parasite attacks by regularly spraying them with water.
You can make the Hibiscus flowers last longer by providing them with water and protect them from severe heat. Heavy downpour can harm Hibiscus flowers. If the Hibiscus plant is exposed to temperatures above 95 degrees F, it can begin to drop its buds. This can sometimes be prevented by giving your Hibiscus plant a lot of water and creating some type of shade for it. The plant itself will have no problem surviving temperatures above 100 degrees F as long as it does not become dehydrated.
Pruning your Hibiscus is recommended since Hibiscus plants tend to produce flowers on their new shoots. You can cut off shoots and use in flower arrangements, but they will usually last no longer than 24 hours. If you cut off an almost opened bud you can protect it in the refrigerator until its time to use it.
Hibiscus plants needs a lot of minerals to do well, including manganese, iron and copper. Giving them some form of flower nutrition or fertilizer is therefore a good idea. Ask your florist for more specified instructions regarding your particular soil and Hibiscus species.
