Bee-utiful borders

I like to plant flower borders around the perimeter of our raised beds, an idea I picked up from a Phoenix Permaculture Guild class we took a few years ago. Not only do they look nice, they attract bees which is helpful if you're trying to grow anything that requires an insect pollinator. And even if you aren't trying to grow food in your backyard, you're doing the environment a favor by providing for the bees.

There's a lot of speculation about why bee populations are declining, but one problem we have in large cities is the "urban desert" effect...buildings, parking lots, roads, and gravelscapes don't provide much in the way of livable habitat for them. The Maricopa County Cooperative Extension ran into this problem when they attempted a community garden project in an area of downtown Phoenix where there is a large homeless population. It was hoped that the garden would not only provide nutritious food to supplement the diets of people living in the area, but that the gardening skills they would learn might help some of them find work. But the Master Gardeners volunteering with the program found that many of the fruits and vegetables they planted never produced anything, because there were no bees living in the area to pollinate them. It would be a very serious problem if bees died out, so I'm happy to help them out any way I can, especially when what makes them happy makes me happy too.

The permaculture class suggested edible flowers, so I use a lot of nasturtiums, but they don't like really hot or cold weather. I usually plant petunias in late fall for winter color and in the spring, sweet alyssum and dwarf marigolds which will take the summer heat. I don't think you can see them, but there are dozens of bees on the alyssum in this photo. It has a sweet, honey-like scent that I think I enjoy as much as the bees do.

This bed contains bush snapbeans, tomatoes, and three kinds of squash. I didn't plant any of the tomatoes; one plant survived the winter and all the others are volunteers. I just put the cages around healthy-looking plants that came up in areas where I didn't have anything else planted. I'm not sure what kind of tomatoes they are as I had several kinds planted here last year. It will be interesting to see what they turn out to be.
