We have maintained existing bulb perennial flowers in the beds, moved a few more around within the garden, and planted mixes of wildflowers along the inside edges of the side beds.
The bulb flowers tend to be spectacular and sometimes grow up to six feet tall. The wildflowers soften the edges of the concrete beds and attract tons of pollinators to the garden. We also plant a few flowers which are known to discourage unwanted insects such as mosquitoes and plant-damaging species. This year, a few of both the bulbs and the wildflowers grew tall enough to shade some of our veggies, which was a side effect we were not expecting. Next year we might be a little more specific about what height of flower gets planted where in the garden. Overall they are a great addition.
