Hi there clks ant. You asked a question in storychat and the editor forwarded it me. I hope this answer reaches you. You said you get about two hours of sun in your front yard as the house is blocking the yard and what can you grow there for color? An easy and obvious choice for the green color to replace the grass is Lirope spicata also known as Creeping Lilyturf. (A picture of mine is above) You can buy creeping lilyturf at any nursery though I don't think it is commonly available in big box stores. You must be sure to buy liriope spicata and NOT liriope muscari if you want it to spread and replace the grass. Liriope is typically known as monkey grass and does extremely well in shade, dry or wet. The muscari type will not move around and forms a clump whereas the spicata type spreads fairly quickly and is an excellent substitute for grass. It will bloom with small purple flowers and usually forms small black berries and grows only about 6-8 inches tall. If you do not want to replace the grass and do not want the liriope to spread then by all means buy the muscari. Spicata should be mowed only one time per year in the spring BEFORE new growth is tall enough to be mowed off. Spicata and muscari are evergreen and no maintenance once they are established. I have both spicata and muscari growing in my garden. I planted the spicata under a silver maple tree where the maple roots prevented mowing of the weeds since no grass would grow there. I put only one sprout every foot or so apart and it completely filled in within two years. It does spread but not like ivy or vinca. If you dig edging in at least 3 inches where you do not want it to grow then you should be fine. That takes care of the grass substitute.
As far as color it is hard to beat hostas, heucheras and pulmonarias-all of which I grow in my garden. There is a tremendous variety of hostas and therefore, no shortage of color. Some of my favorites are: Sun Power (gold in color), Sum and Substance (Lime green and the bloom is fragrant), and Albo-Marginata (a variagated variety). Hostas look best grouped together.
Heucheras, also known as coral bells are commonly available. Heucheras are evergreen and come in a variety of colors. I grow about a dozen varieties in my garden and have found some do better than others. Peach Melba is a peachy colored coral bell but did not do well in my garden. The purple heucheras do much better. Purple varieties include: Palace Purple, Cathedral Bells and Silver Haze. I purchased all of these at a big box store. Heucheras can be divided in the fall but it is best to always start with at least three of any one variety for the most impact. Heucheras do great in shade and are not too picky about soil moisture requiring only the regular moisture rain would provide. Heucheras bloom in the spring by holding dainty flowers well above the foiliage. They do make a big impact and my favorite blooming heuchera is the plain old red one.
You did not say what type of moisture other than the soil is on brick and clay. If the moisture content is average and not too dry then pulmonaria is a great plant. This plant is evergreen and I grow the variety 'Trevi Fountain' which is silver leaved with spots on the leaves. In February or March it will bloom with a multitude of small pink, purple and blue flowers. It is a show stopper and everyone who sees mine loves it. I purchased it mail order about three years ago where it is not too expensive and readily available.
If your soil is dry then Epimediums are supposed to be great. I do not personally grow them but am looking to find some! Epimediums do bloom and are supposed to be versatile. Another plant to try for dry soil which is a green with white varigation low ground cover is Aegopodium podagraria also known as Bishops Weed. I do grow this in my garden. Sometimes people have a terrible time with it spreading but I have not had this problem. It would prefer a moist soil but I have it in dry soil and it does well-sometimes dies back in a drought but always reappears after a rain. I am hesitant to recommend it because it is not always present but does work out well if you don't mind missing it sometimes. It is not evergreen.
Hope these suggestions help with the shady front yard. Some shrubs that do well in the shade are azaleas and hollies. There is a wide variety of hollies and one will surely suit your needs if you are looking for shrubs. I especially like the Helleri Holly. It is low growing, does well in the shade and never needs to be trimmed-my kind of shrub. Azaleas can be picky and I would not recommend them for you if your soil is brick and clay, stick with the hollies.
Please let me know if these work out and I loved it when you said, "Please do not suggest silk flowers!" Too cute and brought a smile to my face. Silk flowers have their place but in a garden in Tennessee is probably not one of them!
