Episode notes

The dream garden of low‑maintenance abundance is all about picking the plants that need hardly any input, just the lightest touch of editing, and they’ll give you months of shifting colour.

In the third episode in this theme with Arthur, we dive into the self-seeding annuals and biennials that bring abundant colour to the garden with very little effort.

From forget-me-nots and violas to cerinthe, cosmos and quaking grasses, they share their favourite ‘volunteer’ plants, how to manage them, and simple ways to use them in borders and cut-flower arrangements for a truly low-maintenance, flower-filled garden.

In this episode, discover:

How to use self-seeding annuals and biennials to create a low‑maintenance, flower‑filled garden that largely looks after itself
Inspired plant recommendations, from forget‑me‑nots and violas, to grasses, nasturtiums and Californian poppies
Practical tips on managing self‑sowers - when to let them run, and when to thin them out
Ways to weave self‑seeders into borders, pots and even cracks in paving for long‑season colour, movement and structure
