I'm in the middle of re-thinking the plantings in the traffic island which is in the center of the road directly in front of our house. We have to make a left turn to enter our drive which is just before the island; just beyond the island the road dips down. The problem is that almost every plant I've tried in this sunny site has been so wildly successful that they're obscuring the view of oncoming traffic.
So I pulled out huge clumps of German iris (taller and more floriferous than in any other spot in the garden), Siberian iris and Nepeta 'Walker's Low.' I've replaced them with Bergenia, an unknown purple-flowered Geranium, Sempervivium 'Edge of Night,' Heuchera 'Marmalade' and a small piece of the Nepeta. I've left the lilies — test bulbs of 'Golden Tycoon' from Brent and Becky's bulbs — because you can see through the stems and they are simply too glorious to remove.
