So farewell Monty Don

In this post-rain episode of cult gardening podcast The Garden Log we say goodbye to the universal uncle Monty Don who is to retire from Gardeners' World. But our Gardeners' World keeps turning, so also enjoy introductions to the gorgeous autumn snowflake (Acis autumnalis) and the Corsican knotweed (Polygonum scoparium) a must-have evergreen perennial for the dry garden.
