Flowers are important not only for aesthetics, but to provide a diverse smorgasbord that encourages pollinators in your garden! It is somewhat arbitrary to divide flowers into annuals and perennials as many which are perennials in their native habitats are annuals here as they will not survive our cold winters. We have put biennials with perennials. Many flowers also have edible parts (flowers, leaves, seeds) and others are considered traditional medicinal plants. Jim also diligently tries to gather as many native wildflower seeds as possible so these also have their own grouping here.
