Thank you everyone! I'm in Sonoma County, in the North Bay Area, Sunset zone 14. Are you sure 15'-20' would be enough? I was thinking more along the lines of 30-40', but I'm really bad at estimating how large things are/need to be. My Mother's top choice would be a Mimosa tree because we see them around town doing so well and they are beautiful. I've heard that mimosas tend to create lots of seedlings, but our neighbor has a mimosa tree and we haven't noticed any seedlings on our property in the 5 years we've been living here. We have a fig tree already, it's actually further up the field and from the right angle it does exactly what I want the new tree to do. I could plant a different fruit tree there, but I was under the impression it would need a larger tree than I had planned on putting in my orchard. Although nut trees tend to grow pretty large, maybe a walnut would be good? I'll have to check my Sunset book again, I looked under 'Plants for growing under oaks' and they only listed shrubs, perennials, etc. Further study told me I should absolutely not plant a Bay Laurel tree, but other than that I'm still pretty clueless. I will return to my Sunset guide, and maybe stop by the 'tree farm' that is close to my house. They have a vested interest in selling me something but are very knowledgeable about growing trees in this area, so it should be helpful. Thanks again, I will return with a list of potential trees I'm thinking of ; )

I was on vacation, returned yesterday, happy to get so many responses to my post, and wonderful feedback. Coolplantsguy - yes, I do love peonies and heirloom plants for that matter, I just don't have the room though I admire them in my neighbors yard. The one we had toppled from the weight of the blooms, I don't know the variety, they were here when we purchased. Thanks for the suggestion, I will consider if I ever find the space again...my lawn gets smaller with each passing year. LOL. Pat, you make me chuckle. I'm like you. I spend so much time planning and thinking things through over the winter, only to find later that I don't like the combos or placement, so I plan again for next year. Some of my plant combos happened by accident & some I've followed suggestions when researching companion plants. I'm still learning how textures compliment eachother, and other things I didn't know to think about a few years back, but it's fun to learn. Summer is too short though. Prairiemoon, I also have Astilbe planted next to my Annabelle, and I enjoy the contrast of the red plumes and darker foliage with the brighter green backdrop of Annabelle. I've learned it's best to NOT fertilize it once it's established, it makes the blooms too heavy and they'll topple. Still, the rain does make them flop, but mine usually bounce back, I have one staked with a support, but it was just planted this year. I also cut my dianthus blooms back before I left for vacation, and returned to a new flush of blooms, the foliage tends to yellow on me though, I need to stop watering, I didn't realize they're drought tolerant. I forget the variety, it's got blue spiky foliage and red flowers. I will have to do more research on hellebores...we added a raised planting bed/retaining wall with a row of purple leaf sandcherries on top, and I'm looking for an underplanting in full sun; the sandcherries will be trimmed into a tree form once established. For now, I planted yellowish hostas at the base for contrast, but I know they won't do well in full sun. I'm glad to hear about Sedum Angelina, mine will be delivered some time this week, now I'm really looking forward to growing them, I just worry about our new dog, she's so rambunctious - she's a chihuahua boston terrier mix, the cutest thing, she likes to grab my plants and tug on them..I'll have to get her some more toys. I was thinking of amending my soil for the iris, adding more grit for drainage, we'll see if that works. I had one aster that bloomed for me, but it was spindly, a combo of dry soil in this area and minimal sun, but my campanula that I moved not too long ago is doing much better, must be the sun. I have to move the asters, just trying to find a location. It's funny about the Autumn Joy Sedum, my husband keeps telling me to pot them up since I can't find the 'right' place for them, I'll have to try that. I do like the blooms, very pretty, and they grow amazingly large after transplanting a single stalk, very impressive. I will try to post a pic of William Baffin rose when I have a chance..the pic is not mine as mine is only a few months new and I'm still learning how to prune them to shape, but my friend has one along their property and it's a stunner, grows upright almost like a tree canopy, and does well in our zone without protection and is disease resistant, with prolific blooms, but I know they have to trim it back regularly, it's a monster. Give me a couple of days and I'll try to post here if I can figure out photobucket. Of the climbers, I have Don Juan and Sombreuil. They died back almost to the ground, but new growth emerged in the spring, so they're still puny and it's the end of July, though I also transplanted them in early spring. We'll see next year if they do better. I purchased Smokebush 'Grace' and 'Golden Spirit' - I've read there's some potential winter die back, mine is only a month new, but I've also heard that they grow like weeds once established, so even with winter die back they'll grow like crazy. 'Golden Spirit' has new growth in a pretty lime green color and grows more upright in form whereas 'Grace' fans out. 'Grace' grows at a house up the street from us and it's just beautiful, especially with the smokey plumes. I ask my husband to slow down every time we drive by. :) Phyl in Chicagoland, I'm embarrassed to post pics. I still consider my landscaping in the beginning stages, most plants aren't mature or established yet, I've moved a lot around, still a work in progress. I had problems with photobucket last time I tried, but I'll see what I can do. I'll tell you though, do an internet search on 'Nancy J. Ondra', I came across her website when researching plants (that's where I got my iris and lemonbalm combo inspiration from) - her garden is to die for, absolutely STUNNING!!! I peruse her garden pics whenever I get the winter blues. Mxk, I was also looking at the Iris pallida but wasn't sure if it would look odd to mix these with the non variegated type. If you like the look of Jacobs Ladder, it reminds me of a shrub, Carol Mackie Daphne. Same variegated foliage, with pretty spring flowers. Connie, this is also my first year with wave petunias and I love them, I have them in hanging baskets. I've read they are self-cleaning, unlike the regular petunias, but I still deadhead here and there. I'd do them again, definitely. The foliage is also very pretty. Gabby, I used to throw tags away, but as the gardening world became more intriguing to me, I've learned to write down the names of my plants on a 'map' of my yard...LOL. Mostly in an attempt to overcome winter blahs, I also compiled a list of plants that need deadheading, cutting back, dividing, etc. so I know what to do come spring. Daylilyluvr, ok, like I said I'm an 'advanced' beginner in the gardening world, still in my learning curve. LOL. I had no idea Sweet William was a biennial. I've had it for two years now, the blooms are stunning, but this year it got all brown and ratty after blooms were spent, I chalked that up to too much watering. I cut it back and it looks like a few blooms are starting to come in again, but I had to remove old dried stems. Web says if you don't let it self seed it will shoot up more stems and act as a perennial...looks like that's what's happening for me as I likely cut back the spent blooms last year too. Crunchpa, my favorite person from the container gardening forum. LOL. I have a TON of containers this year, maybe too many. It takes me over an hour just to water everything, and that's just the containers, but I think I got overzealous and overstuffed them this time around...still, I wouldn't go without my containers, I'm hooked. I love that moss sedum, I'll have to try it. You always have the best pics. I still have dirt to cover until everything is established, I'm waiting patiently though my transplanting doesn't help either. I was looking into that red hot poker at one point, if I remember correctly I think it goes dormant mid season and then comes back again later?? Or am I thinking of something else? Pretty. I'll have to research more of the suggestions here, though I'll probably be losing more lawn in the process. :)

Veronica, I feed my rabbits an alfalfa pellet based diet and a high end one at that. Alfalfa is the #1 ingredient in the bag. I go through about 50-60 lbs of pellets a week. The rabbits also are free fed quality grass hay from our farm in PA, I get a trailer load a year as well as natural foods from the garden and I feed some comfrey and Bidens Alba which is a local plentiful weed. The rabbits love the Bidens Alba, I probably feed 100 lbs of it a week and it is edible by us humans as well. The alfalfa could be the reason the manure is so rich but unlike the alfalfa pellets you can dump the fresh rabbit manure on the garden with no worries of burning. I don't put the manure on fresh as after it drops through the wire it goes in to containers where black soldier fly larvae consume the waste and what goes to the garden is basically their manure. It comes out as a rather odd soil like substance, kind of dry and very crumbly. I give it to all the plants, well most all the plants except the blueberries (it is too alkaline). In my opinion though the rabbits break the food down and the end result (pun intended) is better than just using the alfalfa. I guess an easy way to find out would be to use just alfalfa pellets on some plants and the manure on the others. I know some people sell the rabbit manure for absolutely silly prices but it can be bought cheaply and even acquired for free as a lot of people have pet rabbits. Great idea on the new beds. For what it is worth I think most of the trouble people have here is simply due to the poor soil. The plants get stressed because of the conditions be they soil or temps or humidity. Once you hit that tipping point of survival the game is over. I can't control the temperature and I can't control the humidity so I concentrate on building the soil. If the time and effort is taken to first build the soil and feed it the garden grows itself and makes you look like you know what you are doing. I was talking to Silvia about this and I was telling her I get no nematode damage at all on my plants roots, not even a little. I guess they do not like the rabbit manure at all.

Thanks all for the suggestions! I probably should have explained better in the first place. House is up on a naturally forming slope, with the asphalt driveway rising steeply to meet in. After the snow melted, we noticed that what had been shallow-rooted grass off to the side driveway apex was now about an inch lower, bald, rocky, and pocked with ridges from the water runoff. This area extends ~1-2 feet horizontally before dropping down ~4 feet at a ~45 degree angle. Our idea had been to cut a "L" in the side of the slope, reinforce the earthen backstop with a small rock wall, and level the top area with soil, in effect creating a bit of a terrace for the slope to slow down what we worried might erode more in the coming years (which could eat away the earthen support under the asphalt in our paranoid minds). In the soil up top (we would supplement the dry, rocky, clay) we hoped to plant something pretty-- enough to bring color and foliage most of the year and anchor the top soil a bit. As it was to be to the side of the drive, we were hoping for something with a little vertical height, which might act as a natural flag during winter (as we learned the hard way this year, when the hired plowman drove off the driveway and over a small cobblestone ringed flowerbed buried under the snow). We saw heather at a nursery the prior weekend and thought it looked pretty, offered a little height, and might look nice on a hillside here and also in another part of the yard. Thanks again and hope the description was more helpful (sorry--- haven't figured out how to post pics yet)
