Premium Certified Seed: Excellence in Every Batch

At South West Seeds, we believe the foundation of a successful harvest begins before the seed even hits the soil. For over six years, our dedicated static Seed Plant in Cornwall has set the regional benchmark for quality. By combining locally sourced grain from trusted Cornish farmers with industry-leading cleaning technology, we provide certified seed that consistently hits 99.9% to 100% purity.

Why Choose Our Certified Seed?

We don't just meet industry requirements, we aim to surpass them. We process our grain to the Higher Voluntary Standard (HVS) and beyond, taking out more screenings than standard merchant processing to ensure you receive a clean, uniform, and vigorous product.

  • Unrivaled Purity: Our rigorous cleaning process ensures your seed is free from impurities, giving you the best chance for optimal field establishment.

  • Locally Sourced: By partnering with top-tier growers across Cornwall, we ensure our seed is adapted to local conditions and supports the regional agricultural economy.

  • State-of-the-Art Processing: Every batch is cleaned and technically treated on-site, guaranteeing that your seed is ready for immediate drilling upon delivery.
