I do love my Shasta daisies (Leucanthemum x superbum) that grow in the Moonlight Garden. They have been in the same spots for many years and never fail to produce lots of tall, cheerful blooms all summer.
My only frustration is that I have planted them in a few other spots, trying to spread their glory, but they have never taken off and in fact disappear. I suspect they must be very tasty to rabbits that don't venture this close to the house.
They are practially pest free unless you have slugs and snails from what I understand (I don't have to deal with those pests, I am guessing the local rodents take care of them, but I did get rid of them with Sluggo (organic snail bait) when I first moved in and they have never returned.) Another nice thing about these big daisies is that they make the perfect landing spot for all kinds of friendly bees, bugs, and butterflies. One more thing - they make great cut flowers. If only I would get around to making bouquets for the house!
