While dahlia may be out of consideration, growing flowers next to members of the brassica family isn’t an unattainable dream. There are actually a number of blooms that can bring beauty and benefit to your vegetable row, with nasturtium serving as one of the top options. This flower usually grows shorter than our three brassica vegetables, and that extra ground cover lowers the soil temperature and helps with water retention during the hot summer months.
Nasturtium also serves as a great pest deterrent, as does yarrow. This flowering plant attracts a number of beneficial insects, including those that attack brassica-loving pests. Cabbage moths can be particularly harmful, not only to its namesake plant but to broccoli and cauliflower, too. Those moths, however, have an enemy in certain wasp species. Coincidentally, it’s the same wasps that are attracted to the alluring scent of yarrow. Plant the flower near your crop, and you’ll be gifted with a natural defense.
