|In the picture featuring Prunus laurocerausus on your web-site, you see an Emerald Arboritae, about four 'Otto Luykens|
|I looked at the landscape photo for the Otto Luyken and see the two trees, however unfortunately I am not able to identify them specifically from the photo. They appear to be young trees, though, possibly maples of some kind or even Liquidambar. In my opinion these trees would not be appropriate to plant along the foundation of a house because in short time they will be far too large for the location. Keep in mind that even the so-called small trees usually reach 30 feet at maturity.
Instead, you might look at some of the smaller-growing cultivars of Japanese maple if the spot has organic, evenly moist yet well drained, acidic soil. Or, you might consider using a large shrub such as one of the many viburnums and train it like a tree -- if the location is suited to viburnum.
It is very difficult to make plant suggestions long distance because there are so many different variables -- space available, sun, wind, soil type, moisture levels, etc. Your local professional nursery staff and/or county extension should be able to help you evaluate the growing conditions where you want to plant and knowing that, suggest plants that would thrive there as well as be the right size when they mature and also meet your design goals.
Good luck with your project!
