I would like to grow some “barometer plants” to use as an early warning system for my garden. What plants are first to respond to frost, first to bolt and first to wilt? Is this a waste of time? It’s not a waste of time, but I’m not sure you’d have to invest in any particular variety. I would use half-hardy annuals that are sensitive to frost, such as cosmos lobelia.
Creating a garden with “barometer plants” is indeed a smart strategy to anticipate and respond to changing conditions. While specific plants may vary based on climate and region, choosing half-hardy annuals like cosmos and lobelia is an excellent approach. These plants are indeed sensitive to frost and will typically be among the first to show signs of stress, serving as reliable indicators of impending frost or unfavorable weather conditions.
As Beth Chatto, the renowned plants woman, once remarked, “Right plant, right place.” By selecting plants that naturally respond to environmental cues, you’re creating a living barometer tailored to your garden’s unique microclimate. Observing these indicators can provide valuable insights into the overall health and conditions of your garden, allowing for timely interventions and adjustments. So, while it may not be necessary to invest in specific varieties, cultivating a diverse selection of plants with varying sensitivities can enhance your garden’s resilience and your ability to care for it effectively.
