    Thanks everyone. You have been extreamly helpfull. It would appear the Satomi would be well suited to my location. I am limited in space due to power lines and I like the fact it is resestant to disease. I will put an Eddie's w.w. in the backyard.

    'Satomi' is susceptible to dogwood anthracnose and often has some leaf damage.

    According to Dr. Straley's book "Trees of Vancouver" UBC Press 1992 'Eddie's White Wonder' "is the result of crosses made.....during the late 1930s and early 1940s. ... Most of the seedlings were lost to a flood...., but one of the best seedlings had been moved to Richmond and this is the one from which all of the 'Eddie's White Wonder' have been propagated....One of the original seedlings is in the garden of the hybridizer's son...." Also stated "Trees in private gardens are listed only if they are clearly visible from the street". Expect some of the info would have been from Mr. Eddie's son and possibly from "Vancouver's Heritage Tree Inventory - A Collection of Great Trees in the City" 1983 by Elizabeth Whitelaw and Clarence Sihoe , although this is not stated

    Have not noticed anthracnose on any of the C. kousas here yet in 15+ years, but may have missed it. One straight C. kousa, a seedling likely, is very reluctant to bloom some years with as much as 2-3 years or more between good blooming. C. kousa var. chinensis seems to bloom and fruit especially well every 2nd year. Understand 'China Girl' can be quite floriferous. Those grown are 12-15' tall with 'Satomi' being the lowest and widest at about 14' wide.

    "Symptoms on C. kousa typically remain as foliar lesions and do not progress to the more severe stages."

    Actually what I have seen on 'Satomi' could just as well be something else such as powdery mildew, since I have never collected samples and turned them in for identification.

    However, a friend went to a talk at a trade show years ago where a dogwood specialist (Dr Orton?) said there was a genetic connection between pink bracts and anthracnose susceptibily.

    Have not noticed powdery mildew on the dogwoods here, but have seen what appears to be a powdery mildew of some sort on literally acres of large leaved native maples here.

    "Beyond the leaf spots, a foliar problem that has in recent years become about as serious as any other dogwood disease is powdery mildew....

    Spring symptoms show up as a faint white almost bloomy coating to stems, buds, and leaves. As the summer progresses, leaves will show brown patches, puckering and some reddening. As the symptoms advance, plants look moisture stressed....The disease is most significant in Cornus florida, but will also show up in C. kousa, C. nuttallii, and to a lesser extent some of the shrub species."

    According to one recent 5 year Tennessee study: M.T. mbaga & R.J. Sauve, "Multiple Disease Resistance In Dogwoods (Cornus Spp.) To Foliar Pathogens",
    'Satomi' was considered resistant to powdery mildew, however, "cultivars of C. kousa that were most susceptible to spot anthracnose were 'Lustgarten Weeping', 'Satomi', and 'Wolf Eyes'."
    Please note that this is spot anthracnose (caused by Elsinoe corni) rather than the more serious dogwood anthracnose (caused by Discula destructiva).

    vaguely remember some spots on C. kousa var. chinensis leaves one year.

    What height can one expect the ‘Eddie’s White Wonder ‘ to reach?

    The Vancouver Trees app suggests for the similar Cornus nuttallii , 10-20m in 15-45 (closer to the 10m it seems to me, in the long term)

    Would this apply to the C. x ‘Eddie’s White Wonder’? Or would the cross with C.florida mediate its height?

    What’s the largest ‘Eddie’s White Wonder’ you’ve seen so far and at what age aprox?
