Hi PaL -- Lily of the Valley was my Grandma's favorite plant... they are gorgeous when they start to get all clumped up, I think. We had a yard full of them in a rental in Seattle years ago... people would come and dig up clumps, and they'd fill right back in. Good luck with yours! I don't know if they were damaged or not by not being planted deeply enough the first time. Are you seeing any life to them? It seems highly unlikely to me that they'll resent a little mistreatment at the beginning, especially when we've had these nice spring rains. You could probably buy a pot or two of them from either a nursery or farmer's market and plant those, too. That'll show those pips what they're supposed to do.

The looser the ground is around them, the more likely they'll spread, since they spread from underground rhizomes.
Linda -- Good suggestion to get that Sunset book. Also, there are some fabulous plant databases online. Just start typing the names of the plants you're interested in. If you use their Latin names, you'll often get more detailed advice. Don't forget, you can get free advice from online catalogs as well as from columns and forums.
Even though I am saying so myself, I have put together some terrific potted mixes of flowers. If I were you, I'd look at what the best looking pots have planted in them in your area. No need to reinvent the wheel. Go to the fanciest nurseries and check out what they've got. Then try to find them cheaper in other places if need be. I go for small sized pots... which are best found early in the season. My best looking pots last year were huge pots of trailing begonias, started from corms. I crowded them a little and kept them fed & watered. They were gorgeous and didn't need any other plants with them since they flowered continuously and the foilage was beautiful.
Last year I also had some great luck with pots that had a mix of the newish trailing petunias (the ones that you don't have to pinch or groom). Mine were purple. As long as they stayed watered, they were fabulous and they trailed down two feet. (Sadly, there was a problem here when Mr.P decided to rip out the deck and put in brickwork and that project displaced the pots from their customary spot.)
Anyway, for the water problem, I think those little pellets that hold water worked well for the first week, but pots dry out so fast.... sigh!
Let's see, the petunias were mixed with some burgundy snapdragons that also had bronzed leaves, a bit of some fine-leafed Dusty Miller, some lime-colored sweet potato vine, and some lamium (the silver kind with the purple flowers is the kind I particularly like). The lamium, btw, is currently looking absolutely great 10 months later with only the little boxwood which had been put into the original pots for structure. I tend to crowd the pots full of plants and then sacrifice if I have to. The most important thing is to pick things you like and have a good variety of color and shape... but all having the same general water requirements. If you mix annuals with a small shrub or ornamental grass for structure and some perennials (like the lamium) those pots will look good for months. (In January, the lamium died back, so I cut out all the brown, almost to the soil level. It is now about six-eight inches long again and looking lush with just the box for company.) As for that -- I trimmed the box shrub lightly last fall, stuck all the trimmings in root-tone and then planted them in pots by my fountain where they get an almost continual light spray... I now have about 10 new plants. Yay!
The most fun with planting these is getting to decide on colors. I love to mix purple and orange and red -- but I live in Western Washington where sun is sometimes hard to find. Pinks and purples and white and blues all look good together. I have more trouble with yellows... though I planted yellow begonias this year. (I don't know why, it was red begonias that looked so good last year.)
Snapdragons are a real find for pots -- they can be well-behaved, they'll bloom, and then re-bloom and mine seemed to thrive on being cut back.
If you're really feeling patriotic or have a client who is, there is nothing like a good pot of red geraniums with some silver leafed Artemesia along with a good wash of trailing Lobelia, my preference being the darkest blue Lobelia you can find. Because the geraniums & lobelia won't bloom for a while, try to find an early red (like Nicotania) and an early blue (like a viola) if you need color immediately.
Hmmm, likely more than you may have wanted to know. I DO get carried away. Maybe I'll just head off to the plant store now. <grin>
