3 Planting Plans from a Mature Garden

In his article featured in the 2026 spring issue of Fine Gardening, designer Scott Endres discusses how different categories of plants can help enliven a staid landscape.

In this companion plant-ID guide, Scott highlights the standout trees, shrubs, and perennials that shaped the thoughtful reinvention of an aging garden—plants chosen not only for their beauty but also for their durability, seasonal interest, and ability to knit old and new elements seamlessly together. Use this reference to explore the key performers featured in the article, discover what makes each selection valuable in mature landscapes, and find inspiration for breathing fresh life into gardens that are ready for their next chapter.
