Fennel is an invasive plant, and there are plenty of fennel haters out there, many of them our friends, but every year we let a stand or two of wild fennel take root in our yard anyway. We just had to pause now, while the fennel is high, to say that we love it, because it is hardy and beautiful and grows with no water and no encouragement. Feral fennel bulbs aren’t as good as cultivated bulbs for eating, but we eat the flowers, the fronds and the seeds from these wild stands.
But the real reason we let it grow is because fennel attracts more beneficial insects than any other plant, native or imported, that we’ve ever grown in our yard. It’s impossible to photograph, but our fennel stand is swarming all day, every day, with flying insects of every sort, honeybees, wasps, butterflies, ladybugs and many, many small pollinators which we cannot name. At least ten species at any given glance. It is truly a sight to behold.
