By September the hostas and the heucheras might start looking a little the worse for wear... Oklahoma's summer heat and desiccating winds can be brutal. Fortunately, the viewers eye is easily distracted away from that damage and toward an excellent display of lavender pink blooms topping the stems of Obedient Plant. Coupled with the foliage of Bishop's Weed the garden now has one final fling before the gradual decline in fall begins.
I've been warned by several NGA members that both plants can be aggressively invasive... and I know in good sun and nutritious soil they can and are. But here, in the shade of the Silver Maple, they have filled their spaces and then pretty much stopped spreading... and they have been in this state of stasis for at least the past five, possibly seven, years.
