Basil cultivars

Years ago I started buying plants for the yard, and if I saw it and it was pretty, I bought it. The result was areas full of bits and pieces and mostly flowering little plants that were pretty labor intensive. Then I went to a gardening lecture at our Beaumont Botanical Center where the speaker spoke about a plan for the yard. Crazy talk. He suggested a list of attributes that you would want in any plant in your yard. He also talked about the possibility of using no flowers at all in your landscape!
