Are you saying that orange day lilies are somehow DIFFERENT in their root structure than other day lilies? I have several colors and do not see how one is different than another when they are not blooming and I am moving them around. I planted the outside of my property in the ditch with a double orange I had a bulk of due to a hand me down when a fried decided to clean out an entire garden. They are framed by the road and woods. They are not likely to move into the woods due to shade and the road will keep them from moving forward. My goal was to choke out weeds and saplings and it seems to be working well. The plus side is the walkers all really appreciate when they are in bloom.

I would never plant ivy as it is a major thug here and so easy to get out of control and strangle trees, so hard to get rid of once planted. I have a long ditch also and solved the grass problem for part with a wild mint. I don't know how many people would like it but I love it there, it established itself, eliminated the grass, and blooms with purple flowers that the bees like in summer. I don't do anything to clear out old growth, it takes care of itself. My ditch is full of water all winter but yours may not be, so most plants can't deal with that but the mint can. There are large junipers on top of part of my bank. I planted Rugosa roses on top of some of the bank. They are now 7-8' tall and make a nice screen. They require no care. I also have some horizontal Cotoneaster (deciduous) and native thimbleberry (deciduous) on the top, and on the sides I have planted a mix of sword ferns, St. John's Wort ground cover, Geranium macrorrhyzum, and Symphytum iberis- ground cover Comfrey, a tough plant that spreads and blooms in spring. They help suppress grass and bloom at various times. I originally used black plastic to kill grass before planting the banks. Daylilies are a possibility in a ditch if the grass were eliminated first, they can grow in water. I wasn't up for trying to kill the grass in the ditch itself so I haven't tried them there, grass can grow up around them.

Mystic I appreciate the kind offer but these daylilies come back year after year and bloom nicely and I have a lot of them. I must say that they are my favorite daylily though. They look so natural here in the mountains. These daylilies bloomed nicely this year also; it's just that after they finish they always turn ugly, yellow and brown. Somebody should jump on your offer because the wild type daylilies are wonderful in my opinion.

I have been growing scarlet pimpernel indoors since May. I found them growing in my yard when I was preparing the soil to do a rock garden around my patio in mid April. I did not know what they were but I thought the tiny bright orange flowers were beautiful. So I scooped them up with a lot of soil and popped them in a pot and they have been growing and blooming since then on a southwest facing window sill in my home in San Francisco. I just love the charming little flowers. I would probably not see them in the yard as they are so tiny. I plan on putting the pots outside when they go dormant and start watering them in the spring again when I'll bring them back inside.
