Hey--I've got an antique (Mme Isaac Pereire) that has mint growing under it, Scullcap growing next to it, & I've also put sprouty garlic (from the garlic keeper, you know, w/ green sprouts when you don't eat it fast enuf) that I just stuck in the ground next to the roots. The garlic is supposed to repel pests, but it may be working in conjunction w/ the mint. I do know that except for some minor blackspot, I've had no problems w/ it, other than donating blood when I attempt to prune it. The blooms are fabulous in the spring & sporadically throughout the year, & the fragrance is awesome. My mom says the scent reminds her of roses in her neighborhood in Chicago 60 yrs ago. Hope this helps.
The kiss of the sun for pardon, the song of the birds for mirth, One is nearer God's Heart in a garden, than anywhere else on earth.
