DoubleRoot is a world first hybrid clover, successfully produced by Germinal Horizon
Combining the resilience of Caucasian clover with the lateral growth of white clover, DoubleRoot performs above and below ground in challenging weather conditions
How does DoubleRoot work
Get hybrid clover power
Developed over 30 years by our specialist plant breeding team at the Institute of Biological, Environmental and Rural Sciences (IBERS) at Aberystwyth University, this hybrid clover has unique traits.
DoubleRoot starts growing with a deep taproot that supports early establishment. As the plant matures, it transitions to a dual growth habit:
Above ground: Horizontal stolons spread across the surface, forming new plantlets.
Below ground: Rhizomes grow beneath the surface, producing stems.
DoubleRoot climate smart hybrid cover - Above ground: Horizontal stolons spread across the surface, forming new plantlets. Below ground: Rhizomes grow beneath the surface, producing stems.
Why choose DoubleRoot?
Climate Smart clover for amenity spaces
DoubleRoot is a go-to solution for low-maintenance, climate smart landscapes.
This innovative clover adapts to a wide range of soils and climates, with better drought tolerance and cold recovery than standard clovers. The ability to grow nitrogen fixing clover, in more diverse climates, increases the opportunity for landscapers to reduce the need for synthetic nitrogen applications.
Excess use of synthetic nitrogen fertilisers is not only costly, it also releases nitrous oxide into the atmosphere. Nitrous oxide is around 300 times more potent than carbon dioxide as a greenhouse gas. Additionally, nitrogen fertiliser can leach into watercourses, causing water pollution.
Choosing DoubleRoot helps reduce reliance on these fertilisers and their harmful environmental effects. This makes it an ideal choice for high-traffic areas such as roadside verges, parks, and public spaces.
Understanding the challenges
Balancing project costs against environmental considerations
Increased focus on transitioning to more sustainable solutions for the amenity sector
Increasing weather extremes due to climate change is putting pressure on plants
Nitrogen is one of the most commonly deficient nutrients in many soils but excess chemical fertiliser is costly and can harm water sources
Nature decline and lack of species diversity is having a negative impact on our green spaces
