Talk about a pop of colour. The Cranberry Hibiscus is an absolute, surefire way to add some vibrancy to your garden. The leaves display such a deep mulberry red colour and the flowers have a beautiful cranberry red colour that just radiates against its leaves. The bonus to having a Cranberry Hibiscus is that they are very easy to grow and maintain. They require very little intervention and are a true show-stopper. Not only are they easy to grow, but they are also quite a fast-growing plant, meaning you can have beautiful flowers in little to no time.
They are native to Africa, so they tend to prefer warmer climates. However, these stunning specimens can be grown in zones 8-11 and will tolerate some cold.

LIGHT
Planting your Cranberry Hibiscus in full sun will promote healthy growth and increase flowering. These stunning perennials will tolerate some shade, however, this will slow down the flowering time and can lead to less vibrant foliage and flowers. In extreme summer conditions, the leaves can be susceptible to scorching, therefore, I recommend placing your Cranberry Hibiscus in a position in your garden that gets some afternoon shade.
WATER
The Cranberry Hibiscus is susceptible to root rot if over-watered or if planted in poor soil. Be sure to water regularly during warmer months and ensure you have adequately drawing soil. To avoid fungal disease in the leaves, avoid overhead watering. I always like to add some mulch to the base of all my plants, including the Cranberry Hibiscus. Not only will this aid in soil temperature, but it will also help to maintain soil moisture.
SOIL
To keep your Cranberry Hibiscus happy you will need to plant it in well-draining soil. You can grow these beauties in the ground and they will also do well in a pot. Ensure your soil is fertile by adding some plant matter such as compost and aim for a pH level around 5.5-7.0. This is a slightly acidic soil that will benefit the vibrancy of the plant. Like other hibiscus varieties, the Cranberry Hibiscus does not like wet feet, so ensure that any heavy, clay-like soil is broken up before planting. You can achieve this by adding additional compost or a sprinkling of Gypsum solution to the soil to help break down the clay. The addition of mulch to the top of the soil will also contribute to the nutrients of the plant as it breaks down over time.Â
The Cranberry hibiscus is also a culinary plant. The leaves of the Cranberry Hibiscus can be eaten raw in salads or on their own and they have a slightly tangy flavour. I particularly like using them for flower arrangements in my house as the vibrant reds look so stunning among other cut flowers or as one big bunch of red foliage!
