sng: I like the way you research. Do a copy and paste for -- Callistemon phoeniceus -- and you will find considerable info on the web via Google. I have a feeling you've misspelled it somehow. It's a shrub to about ten to fifteen feet, easily trained into a "standard" or multi-trunked "tree". "Escallonia x exoniensis ÂBalfouriÂ, E. laevis, E. rubra ESCALLONIA We excluded Escallonia for making the following assumptions:" Your assumptions are inaccurate. The common Escallonias are almost always trimmed into tight hedgelike masses; hence making it hard to see the potential as a small tree. Along the coast, especially, the listed ones (not so common) make great multi-trunk small trees. -Melaleuca armillaris BRACELET MYRTLE -Melaleuca ericifolia HEATH MELALEUCA "I have probably seen these plants somewhere but do not remember if they are dense enough for our purpose. I will try finding them in our neighborhood and do more research." Although these species have fine-textured foliage, they do grow into densely-foliaged small trees. I'm attaching a photo of one (they look alike). -Metrosideros collinus ÂSpringfire NEW ZEALAND CHRISTMAS TREE "I always liked this tree but never knew the name. The street I take every day to work is dressed with this tree on both sides and they are quite tall, probably 20-30 feet (may be M. excelsus?)." The "trees" you see are M. excelsus and they get bigger than 30 feet. M. collinus is smaller. And conseuqently slower growing. -Pittosporum crassifolium KARO "I see this planted practically everywhere I go. (Maybe because I live near ocean and work near SF bay?) SF Botanical Garden uses it to screen chain link fences and it does the job so well. I really love the slivery blue green foliage of this plant that goes beautifully with the deep maroon color of its flower. Urban Forest Ecosystems Institute marked all PittosporumÂs health hazard as allergy, except for P. tenuifolium that was marked as unknown. I had no way of telling likelihood of causing allergy but did not want to take any risk so dropped all Pittosporum from my list except for P. tenuifolium. But now I have a further reference on this so I will definitely reconsider P. crassifolium. Thank you again." There are over 160 species of Pittosporum. I doubt that all of them are allergenic. The two most common ones (P. undulatum and P. tobira) are highly fragrant and, because of that, highly allergenic to many people. P. crassifolium is not significantly fragrant (as with P. ten.).

You'll smell root rot and see actual rot if it's present. It's just like rotten food. When the drainage is poor the hole needs to be dug larger and you should have a "drain" hole at the bottom of the hole. Typically folks fill a drain with rock. It should go below the hardpan of earth so the water has a place to go. Unless absolutely necessary, your soil should never be amended but there are circumstances where it should be amendment. Never use more than 1/3 amendment to your native soil. A good amendment is sold at home improvement stores and it's called something like "tree and shrub amendment." It has bark fines and peat moss, basically. You should be using a pick axe to do your plantings. Also, when your hole is opened up, you should drive the pick axe all around the sides of the planting hole creating "pockets" for the roots to go into. To drive thru the hard pan you may need more than a pick axe. I'll provide you with a link that will help you. Dax Here is a link that might be useful: Preparing Hardpan For Plantings

Laurel Rhododendren - not all all evergreen Azalea - not all all evergreen Viburnum - not all all evergreen Hydrangeas are not evergreen, but come in different sizes/colors. Clumping bamboo should work, but please avoid the running variety, unless you want it coming right through your foundation. Shade makes things difficult. It rules out most evergreens and grasses. If you buy from the big box stores, keep your receipt. I have ~ 60% success rate.

A lot of the clumping bamboos (most, I believe), that are hardy in zones 7 and 8 are subtropical mountain species. Which means..., they are not as hardy to extreme cold or too extreme heat as that notorious running genus, Phyllostachys (you don't wanna go there!). F. rufa seems the most commonly available in the Mid Atlantic area. It is a nice species and does put up well with our hot nights (a potential issue with many of the mountain species). It has seen temps from 4F to 109 without any burning. It is not cheap, and you will not get a privacy wall overnight, but will, eventually, if it likes its positioning. Some shade from the hottest sun is definitely a big advantage. It is well-behaved and will not be invasive, but will form a dense grove. We have Fargesia rufa (Green Panda Bamboo). Started with little pots and every year would divide each plant to lengthen 'the wall'. Growing area gets morning sun and dappled midday. It is never watered nor fed.
