Hills will be supplying 10,000 of the plants via Sainsbury's in time for Mother's Day and 5,000 through Waitrose for the summer season.
Magical Hydrangeas are a new variety of indoor hydrangea with an "outstanding" lifespan. The plants are designed to flower for 150 days, and slowly change colour when exposed to daylight. The Magical Revolution Hydrangea begins flowering in pink or blue with the flowers turning to dark red.
Each Magical Hydrangea comes with a 150 day flower challenge which runs from 3 April 2017 to 1 September 2017, and those buying the plant can register online.
Sarah Gainsborough, brand and NPD manager at Hills Plants, said: "We are delighted to be supplying these bold and beautiful plants which are perfect for Mother's Day or as a gift for a special friend or family member. There is a growing trend in the UK for indoor plants again, and to bring the outside in to create more green space inside our homes. Magical Hydrangeas provide gorgeous big flowers that last and last - and are a stunning and unique gift."
