Hibiscus care instructions

Hibiscus on Lazy Flora

I've made no secret of the fact that Hibiscus is my favourite plant, so I'm delighted to introduce this plant to you as our July 2018 indoor plant of the month.

'Indoor plant?', you say

Yes, indoor plant. In the UK climate, hibiscus often do best as indoor plants. 

There are two types of hibiscus. There's a tropical hibiscus that thrives in very hot, humid conditions like those in the Caribbean or South Pacific, and there's a hardy hibiscus, which you often see in southern Europe. In fact, even in the south of the UK, hibiscus can do really well as outdoor plants, providing they are placed in a sunny spot, and protected from low temperatures during the winter.

The hibiscus in our Lazy Flora collection is the latter: it's a 'hardy' European hibiscus. But 'hardy' means it still needs protecting from low temperatures in winter, and it's why you don't see many in cooler parts of the UK. It's also why it does best as a houseplant. I have had many hibiscus plants throughout my life, and have enjoyed their spectacular blooms both on sunny spots inside my home, as well as on my sunny balcony in summer.

Light and position in the home

Hibiscus loves bright, direct sunshine. In your home, it will love a sunny windowsill. Place it on a South, West or even East-facing window and it will thank you by throwing forth lots of outrageous flowers in summer time.

If you do have a sunny outdoor space in summer, your hibiscus will also do really well outdoors during the summer months too, but be sure to bring it inside before the temperatures start to drop, as these plants are very sensitive to cold temperatures, especially when they are small plants.


Hibiscus like constant, warm to hot temperatures. Avoid draughts and in winter, ensure it isn't exposed to temperatures below 10 degrees.


Hibiscus require a moderate, but not excessive, amount of water. The soil should be on the dry side of moist at all times, but ensure that it is never standing in water, because the roots will rot. In winter, avoid watering with cold water. If you can give it warm or tepid water, it will be less of a shock to the plant.

Always water from the roots, especially during the summer when flowers are present, because the flowers can be very easily damaged by the force and weight of the water.

Flowering and blooms

Hibiscus flowers are some of the most spectacular in all of nature. The flowers are huge, bold and totally Instagram-worthy. Flowers last just a few days, but you should see lots of them, especially in late summer. This plant won't flower all year - it's a late summer flowering plant. To encourage flowering, treat with a mild fertilizer once a week between March and October, making sure that the soil is thoroughly wet before introducing fertilizer.

So I hope you see now why I love this plant so much! If you're curious enough to want one for yourself, head on over to our indoor plants page.
