Also tomato leaves can yellow at the bottom due to over watering. Sometimes this can not be helped due to Mother Nature.

Liatris spicata goes by many names: blazing star, gayfeather, liatris, and button snakeroot. Butterflies (and bees) love it no matter what the name. With showy purple spikes of flowers and leaves that appear like clumps of grass, blazing star is an interesting addition to any perennial garden. Try adding a few white varieties (Liatris spicata 'alba') to a butterfly bed for more contrast.
