I think interplanting to hide the dying foliage is a good idea, but you should also read hunt4carl's response in this thread here about inter planting daylillies http://forums.gardenweb.com/discussions/2059525/interplanting-w-daylilies

I think a good spot for planting would be that stretch of grass near the street. Take the lawn out and make it into a perennial bed for your daylilies and some nice evergreens.

Yes to the question. Beds along side the drive would be ugly and cluttered. I used to have a No Plant Left Behind attitude about plants. Any perennial I divided had to make a new home somewhere else in my garden. Not anymore. Gardening is so much more enjoyable now that I no longer have plant guilt on my mind.

Melle had a good idea with the sidewalk bed.

If none of your friends want the daylilies you should just toss them.

I hate tossing them with as much as I paid for them. I might use some to block rabbit holes in the back yard. Did you mean the area around the mailbox? I worry about putting bee-attracting plants around the mailbox - could make the mailman stop delivering. I have been wanting to put something there though.

Thanks for the input yard! I just looked it up on the aspca's toxic plant list. It was listed as toxic to cats. I suppose some cats are chewers. Do you have any thoughts on continuing a flower bed around to the north side of the house when there's a drainage pipe (french drain?) on that side? The guy that installed it seemed to think it was fine to plant flowers in front of it as long as I didn't cover it with dirt or mulch, but he didn't like the idea of continuing the bed (with the wall and all) - said it would defeat the purpose. I don't see how, as the purpose was to divert water away from the house. The downspouts would still be tied into the drain and I wouldn't be covering the rocks on top of it.

You can always 'trade' your daylilies on the Plant exchange forum for bushes or trees that you might like. I have traded lots of different plants there. Just post what you have, name if you know it and a picture or description of color and what your are interested in.

I have no understanding of your north side and its drainage pipe so can offer no advice.

dense plantings can create a dam of sorts, blocking water's escape. Maybe that's what your contractor was talking about.
During our last very heavy rain, I was digging and moving mondo grass because it was preventing the rainwater from flowing out of the bed. I never realized before how an edging (my edging is mondo grass) could cause local flooding of a flower bed.

Sorry I didn't add a picture before, but I think it was too late to get one. I don't know if this will help any, but here's a picture.

There's some kind of perforated pipe under those rocks. Also, the downspouts are connected to it (see the black tube?). It goes that way into the back yard all along the side of the house and along the retaining wall in the back. Then it switches to a solid buried pipe. That runs to the back edge of my yard where it is connected to a pop-up drain. When it rains, water is supposed to run through this piping system and the force of the water pushes the drain to pop up and water is dispersed at the back edge of my yard instead of collecting by my house. I don't know if that's considered a true French drain, because I thought those usually had some collection pit or something at the end for the water...mine doesn't...it just kind of dumps it back there. Anyway I was kind of thinking I could take the existing flower bed and expand it to wrap around the corner, leaving a little space at the back so the drain doesn't get covered in dirt or whatever. I guess I just didn't see how this would defeat the purpose of the drain.

Update: I just realized that if I tried to continue the bed around, the wall wouldn't be able to come against the foundation to close it off because the drain is there. There would be a gap. I wonder if that would look funny...

Can't speak to your drain affair, but it seems that a bed adjacent stands a good chance of getting dirt mixed into the gravel. Why can't you create a nice bed of daylilies in front of the wood fence?

I figured to avoid getting dirt mixed into the drain rock I'd have to leave a swath at least a foot wide between it and the back side of the bed continuation. Maybe even some kind of barrier. May not be worth it.

In front of the fence is an idea...it wouldn't look too random all alone over there? I may consider doing that. How should it be shaped there? Just some gentle curves? Or squared off? Maybe a half circle. Should I have one by the fence on each side of the house for balance? Probably need to get the fence restained before I plant near it...it's overdue :/

I do think I'll practice in the back yard before I do anything in the front. Professional did all the planting before and I may make a mess before I figure out what I'm doing. Hopefully I don't kill my daylilies when I dig them up and try to divide them.

Thanks for all the ideas and input everyone!

Would be difficult/impossible to speculate on how a bed should be shaped without seeing the space and surrounding context.

Daylilies are some of the toughest plants around, have fun!

I volunteer and take care of city park beds. I accept daylilies, irises, anything anyone wants to donate. Try Freecycle.com or just post on Facebook. You can meet them at Burger King and transfer from one trunk to another and they don't have to know where you live if you're concerned about those kinds of things.
