It’s a concern being voiced by conscientious gardeners everywhere: is it okay to plant a non-native flower that feeds pollinators but also self-sows freely? One suspect that is being discussed in many online gardening groups in borage. It shows up in pollinator-garden seed mixes that the purchasers expected to be 100% native. It features at seed swaps and in seed libraries because its seeds are easy to collect, and established gardeners know it always brings the bees in. But it also sows itself aggressively, and it didn’t evolve alongside North American pollinators. The people want to know: is it problematic to grow it? Is an aggressive plant necessarily invasive? That’s the question that sets the stage for this week’s versus episode. Sean takes on the borage question while Erin examines her own potentially-problematic fave, cosmos. They look into each plant’s origins, its spread around the world, and how manageable it is once it’s in your garden. They examine studies about wildlife use and raise questions about nectar and pollen quality. Along the way, they uncover a treasure trove of interesting science…and a wealth of questions still to be answered. Who brought the most fascinating facts about their plant this week?
