Plant this Button snakeroot may sound like something straight out of Harry Potter, but this plant (Latin name Eryngium yuccifolium) is a valuable addition to a late-summer wildlife border. Its grey-green spiky flowerheads will be covered in bees this month and next. Height and spread: 1m x 1m.
Save this Pick a dry day to collect seeds from your favourite garden flowers, such as poppies, astrantias, scabious and aquilegias. Make sure the seed heads are dry and papery, then snip off stems and hang upside down in a cool, airy spot. Cover with a paper bag to catch your harvest.
Support this If you prefer to fill your vases with local, seasonal flowers, support the growing British cut-flower industry by finding your nearest grower via Flowers From the Farm, a not-for-profit cooperative. Check its blog for advice on starting your own cut-flower garden.
