The plant known as blue hibiscus is actually Blue Pea (Clitoria ternatea). Keep it in a sunny spot and use light, crumbly soil. You should water it regularly. It can be easily grown in a pot on the balcony. So, decorate your balcony with blue flowers.
White Hibiscus
For a minimal and clean look, white hibiscus is the best flower plant. To make a small balcony space feel open, decorate with white hibiscus instead of red.
