As a professional a garden coach, designer and maintainer, I am frequently asked to identify plants that have 'just appeared' on a property. When unsure of an identity I grab a couple of photos and head for two websites, The Connecticut Botanical Society and Go Botany. I have yet to come away without a positive ID.
We gardeners spend so much time cultivating gardens that we often missing a chance to learn about plants growing of their own accord in natural settings. I avoided a Gardening Oops – GOOPs for short – simply by taking some time to wander outside of my cultivated beds.
