Index Seminum Page (2021 update)

As the UK has left the EU and with the resulting increase in costs for issuing Phytosanitary Certificates and inspections we regret we are unable to participate with the International Plant Exchange Network Index Seminum programme in the normal way

We are hopeful that exemptions or assistance to cover the cost may eventually be forthcoming but at the moment 29/01/21, the Index Seminum is open to UK Gardens only
