Recent Trends in Late Summer Garden Design
Gardeners and landscape designers have increasingly focused on extending garden interest into the late summer and fall months, especially as climate patterns shift and growing seasons become less predictable. The trend toward quick, impactful planting options aligns with this goal.
Historically, many gardeners relied on perennials and slower-growing annuals, but recent advice from horticultural experts highlights the benefits of fast-growing annuals and perennials for filling seasonal gaps. This approach helps maintain garden vibrancy and supports pollinator activity late into the season.
Additionally, recent garden shows and publications have spotlighted these eight plants as reliable choices for late summer color, reflecting a broader shift toward practical, visually impactful gardening solutions.
