In addition to the main Bulb & Seed Exchanges in summer, Jon Evans also arranges exchanges for “ephemeral” seeds, which ripen in autumn and must be sown as soon as possible after they ripen, and are therefore not suitable to be saved until the main exchange the following year.

More details will be added here in due course. Some information on previous ephemeral exchanges appears below.

• Ephemeral seeds available 20-22 November 2018
• Ephemeral seeds available 14-25 November 2021
• November 2023 Ephemeral Seed and Bulb Exchange (in progress)
