Let's delve into the details.
What is Hibiscus rosa-sinensis 'Red Hot'?
'Red Hot' is a cultivar of the Hibiscus rosa-sinensis, a species native to East Asia. It's characterized by its deep, crimson-red flowers, which are often described as a fiery, almost scarlet hue. The blooms are large, trumpet-shaped, and typically have a prominent stamen column. The leaves are a glossy dark green, providing a beautiful contrast to the intense flower color. This variety is prized for its consistently bright blooms and relatively easy care, making it a favorite among both beginner and experienced gardeners.

The size of your 'Red Hot' hibiscus will depend largely on growing conditions. In ideal conditions, including ample sunlight and consistent watering, it can reach heights of 4-6 feet (1.2-1.8 meters) and a similar spread. However, with regular pruning, you can easily maintain a smaller, more compact size, making it suitable even for containers on patios or balconies.

Under ideal conditions, 'Red Hot' hibiscus can bloom prolifically throughout the warmer months, from spring to fall. Consistent blooming requires sufficient sunlight, proper watering, and regular fertilization.

What is the best soil for Hibiscus rosa-sinensis 'Red Hot'?
This hibiscus thrives in well-drained, slightly acidic soil (pH 6.0-6.5). A soil mix that retains some moisture but doesn't become waterlogged is ideal. Adding organic matter like compost to your garden soil can improve drainage and provide essential nutrients. For container-grown plants, a well-draining potting mix is crucial.
How much sunlight does Hibiscus rosa-sinensis 'Red Hot' need?

Propagation is relatively easy with 'Red Hot' hibiscus. Stem cuttings are a common method. Take a 4-6 inch cutting from a healthy stem, remove the lower leaves, and dip the cut end in rooting hormone before planting in a moist potting mix. Keep the cutting moist and warm, and you should see roots develop within a few weeks.

No, Hibiscus rosa-sinensis 'Red Hot', as a cultivated variety, is not considered invasive. It does not readily self-seed or spread aggressively beyond its planted area.
Are Hibiscus rosa-sinensis 'Red Hot' flowers edible?
While hibiscus flowers are often used in teas and other culinary applications, it's crucial to note that there is no reliable information supporting the edibility of Hibiscus rosa-sinensis 'Red Hot' specifically.
