As some plants complete their life cycle in the garden, it's the perfect opportunity for the gardener to reap a bountiful seed harvest. Toby Buckland explains which plants to go for and how to collect and store them. For Carol Klein, late summer is the time when some plants are looking their most spectacular and, at Glebe Cottage, it's the Japanese anemone which is shining out from her borders. Joe Swift offers design tips for seating areas, and Toby joins him to make one with a contemporary edge at Greenacre. Plus, the garden of the first of the five finalists in the BBC Gardener of the Year competition is revealed.

September is the month when exotic plants reach their exuberant best, and in the tropical border at Greenacre Toby shows us which plants have performed.
