Red Bee Balm, Pink Yarrow, Echinacea, Roses and Rudbeckia growing together in the front garden. I quickly found out how aggressive these plants are and moved many of them into the butterfly or far acre garden where they could spread. I truly love the red bee balm. Yarrow is great for all season color as long as you deadhead it. Deadheading is nothing more than cutting off the faded blooms. Rudbeckia is another favorite. I love the cheery yellow color.
