Anthony and I have considered carefully how much of the garden we want to allocate to native plants that aren't a direct food source for ourselves vs. traditional orchard and vegetable plants that do feed us. So far we've tried to learn as much as we can about native edibles and have designed the garden to include them.
But it was exciting to learn through the Shutterbee program (read more about that here) that native bees can make great use of traditional vegetable and herb flowers as a pollen source. That's right: As part of my training as a citizen scientist conducting bee studies in my own yard, I was instructed not to overlook the vegetable patch and herb garden.
Most efforts to promote pollinator habitats focus on native flowers such as milkweed and coneflower, which are terrific additions to the garden that we've definitely incorporated. But this is the first I've heard that food plants could support native bees! That's an exciting finding because it means the annual vegetables we're growing get an added "stacked function." In permaculture, that means it has more than one use in the garden - here as both food source for us and a pollen and nectar source for bees. There's even a specialized 'squash bee' that is so-named because it prefers the flowers of squash plants.
For my first official foray into the farmyard to record bees, I was pleased to find that indeed, native bees were busy taking advantage of the flowering vegetable plants. I'd left the arugula standing when it bolted in the summer heat, and it's popular with tiny sweat bees.
So that's one more compelling reason to grow food in your yard. The list was already pretty long, but here's what we've got now. By growing your own food, you will:
- Save money, especially if you grow from seeds. You could also get a secondary set of money savings from a reduced need for medicinal interventions, whether that's from traditional medicine or alternatives.
- Eat healthier, as your food won't lose integrity via shipping and storing, and if you grow organically, you'll cut out pesticide contamination. You're also likely to eat more veggies because they're fresh and tasty.
- Get more in touch with the cycle of life as you take part in it as a mulcher, composter, and seed-sower.
- Enjoy a motivating daily workout as you put sweat equity into something that yields more than a toned physique.
- And now we can add: Help pollinators by providing them a much better food source than turf grass!
Of course, if you want pollinators to take advantage of the flowers, you need to leave them there. The broccoli I started from seed indoors mostly faltered, but a few took off, and then quickly bolted (next year, we try a different approach). The flowers are pretty, so why not let them go? Ditto the chervil and arugula, both of which love cool weather and are pretty much done now that it's 90+ degrees here in June. That reminds me, the arugula is about to go to seed, so I better get out there and snag the remaining leaves...
Happy yardening! I wish you mulch success!
