Chinese Wisteria is an aggressive vine that should be grown with care. My best advice is to keep it pruned and provide a strong support. I'll have more pictures of this plant in the next couple of weeks as it fills my arbor with massive quantities of flowers. The picture below is of a smaller plant that I'm growing in a pot as I attempt to train it into a topiary form.
This Blue Ajuga was just planted last summer, but it's already putting out plenty of those great sapphire blue flowers that I love.
Rainbow Ajuga doesn't have fancy flowers, but it's attractive foliage provides interest all year long.
