The first commercial planting of seed-based Miscanthus plugs in Germany marks the latest breakthrough in more than 20 years of UK innovation, to upscale crop planting to support net zero targets in the UK and Europe.
Currently, Miscanthus is grown from rhizome (rootstock). The commercial species of plants do not produce seed, and the only way to propagate the crop is to lift the rhizomes, split and replant them.
“You can only propagate rhizomes once every three years, as they need to grow to the right size. One hectare of a propagated rhizome crop yields 13-20 hectares of root stock. With seed, a one-hectare crossing block can produce 2,000 hectares of new crop, so the potential is vast,” explains Florian Ilias from UK-based Miscanthus specialist, Terravesta.
Advances in crop genetics, propagation and planting technology are now coming together to enable large-scale commercial production of seed-based crops, with the advantage of increasing plant density from 17,000 rhizomes per hectare to over 20,000 seed-based plugs per hectare.
“The real advantage is scale; We can establish seed-based Miscanthus much faster than crops grown from rhizomes,” explains Florian.
Increased demand for Miscanthus fibre
Across Europe and the UK, demand for sustainable biomass is growing rapidly as governments and industry work towards net zero and a circular bioeconomy. Miscanthus is recognised as one of the leading perennial biomass crops to support this transition, with applications spanning renewable energy, sustainable construction materials and bio-based products.
Policy ambition reflects this growing demand. Under the EU’s Renewable Energy Directive (RED III), Member States are incentivised to increase domestic biomass production, while in the UK the Climate Change Committee recommends planting 30,000 hectares of perennial biomass crops each year by 2035, rising to 700,000 hectares by 2050.
However, current planting falls far short of these ambitions. There are only around 20,000 hectares of Miscanthus across the EU and around 7,500 hectares in the UK. Advances in crop genetics and commercial plug planting are now helping to accelerate establishment, providing the scale needed to support the next phase of growth in the bioeconomy.
The first commercial plug planting
This spring 2026, the first commercial-scale planting of Miscanthus plugs grown from seed was successfully completed in Germany by UK-based Miscanthus specialist, Terravesta, marking a significant milestone in the evolution of Miscanthus establishment. Traditionally planted using rhizomes, commercial plug planting provides the practical route to establishing much larger areas of crop within the narrow planting window needed for large-scale deployment.
Across 12 hectares, 130,000 plugs were successfully planted and established.
“This isn’t about replacing rhizomes,” says Florian Ilias, Terravesta managing director. “It’s about unlocking scale. For Miscanthus to play the role needed in delivering net zero and supplying future bio-based industries, we need planting systems capable of establishing thousands of hectares efficiently. Commercial plug planting gets us much closer to that goal.”
The German planting also demonstrated where future gains will come. “The plug planting in Germany has highlighted improvements which would increase the speed of planting.
“Work is already underway to develop fully automated planting systems with larger onboard storage, improved field resupply systems and enhanced propagation trays that support stronger root development and faster planting,” says Florian. “A fully automated system will enable planting densities of 20,000 plugs per hectare,” says Florian.
“The breakthrough isn’t simply establishing more seed-based plugs,” explains Florian. “It’s developing a complete system that allows Miscanthus to be established at a commercial scale anywhere in the world.”
The first commercial planting of Miscanthus plugs demonstrates that one of the biggest barriers to expansion is now being overcome.
The technology to scale Miscanthus is no longer a future ambition; it has arrived.
