When it comes to choosing a planting scheme, I'm a throw-it-in-the-pot-and-hope-for-the-best kind of guy. The biggest attraction in my yard is underneath a large bonsai tree. I've set a brick border around its perimeter, and within the border I've planted liriope, mexican heather, and moss rose.
I've talked with a couple of colleagues about the nature of both liriope and mexican heather. Most agree that liriope spreads like wildfire over the yard while also spreading its' roots out underground. Concerning the latter, I've heard the same thing said about mexican heather.
I feel like my moss roses are going to get lost in the olla. They are tiny flowers compared to their current roommates and I'm pretty sure they aren't taking to the shade underneath the bonsai. Furthermore, I'm concerned that the liriope and heather are engaged in a silent battle for real estate. Have I erred in my plant selection? If so, what - if any - plant(s) compliment liriope and/or mexican heather?
