    I am curious if the Davidia involucrata would do well in moist soils? I live in south western BC, zone 8.

    Moist with good drainage should be fine, some shade seems to be good also.

    They do well in moist soils, they will not tolerate drought. The tree is prone to fork, and put out branches sideways. These should be trimmed back. Very tolerant of insects here. It should be planted more widely locally, it does quite well here, and is not to big.

    A "search" of "Davidia" in the title bar near the top of this page will bring up more info. Not sure about size, an older one at Ferncliff Garden in Hatzic, B.C. seemed to be +60' across. A pic of one at Riverview looks very nice and blooming young. Believe the cultivar "Sonoma" blooms at a young age, seed grown trees can take 15+ years to bloom well.

    Sonoma Horticultural Nursery gives the cultivar name as 'SHN'. I have seen it blooming in 5 gallon containers at outlets here, on more than one occasion.

    I wouldn't prune the branches back. Wide crown of long branches seems to be the normal mode, plus you want to have long branches for the flowerheads to hang from. Not a small tree, you need to give it a wide berth anyway.

    Grabbing THE PRUNING OF TREES, SHRUBS AND CONIFERS I see it says

    "The outline of a mature tree is wide and spreading, for the leader finally terminates in branching at an approximate height of 9 m. (30 ft.) or more. The spreading branches should not be restricted by lack of sufficient light or pruning, otherwise the effect will be spoilt. As a tree gains height and grows freely, the lower branches may be removed back to the stem to form a 1.8 m. (6 ft.) clear trunk if desired, doing this in the later summer. This is a good form in which to grow the tree, as the showy bracts, hanging down, may be seen to full effect. The process of forming a clear stem may start in the nursery, but the head will not be complete for at least a year or so after the final planting."

    The only large one I've seen is in Vancouver on SW Marine Dr. Thanks for your responses.

    Straley, TREES OF GREATER VANCOUVER says where the one that hangs out over SW Marine Drive, gives locations of others. Last time I was at UBC, several years ago there was a new one in the shop there by a different author, although it seemed to have quite a few small specimens indicated maybe it also has locations for a dove tree or two that is fairly well along - I don't remember.

    Three plants that I know of:

    The one on Southwest Marine Drive and 49th is a delight to see on my morning commutes in May. I've heard it said that this is the largest one in the Lower Mainland of BC.

    Two plants in UBC BG: one on the accessibility path where it is closest to the ocean in the Asian Garden (the second largest in Lower Mainland of BC?), a second that is slightly smaller near the stand-out Cunninghamia lanceolata 'Glauca' from one of the side paths off Upper Asian Way.

    >Not sure about size, an older one at Ferncliff Garden in Hatzic, B.C. seemed to be +60' across<

    Sounds like that may be the biggest one there, if that big and still extant. Down here (WA) we have this record (from Van Pelt, CHAMPION TREES OF WASHINGTON STATE (1996)):

    Circumference: 5'4"
    Height: 53'
    Crown Spread: 52'
    AFA* Points: 130
    Date Last Measured: 1988
    Location and Nominators: Snohomish, 1314 Third St RGB

    One in Seattle was 52 1/2' tall during 2006 (Jacobson, TREES OF SEATTLE - SECOND EDITION). NORTH AMERICAN LANDSCAPE TREES (Jacobson, 1996) lists the following records for cultivated specimens (all height x circumference):

    79' x 6'6" Westonbirt, Gloucestershire, England (1988)
    72' x 8'1" Villa Taranto, Pallanza, Lake Maggiore, Italy (1994)
    62' x 7'6" Tregrehan, Cornwall, England (1979)

    *American Forestry Association, since shortened to American Forests; Van Pelt used same point system they do for numerous species not actually kept track of by AF. It's a way of assigning a single figure that gives an indication of the overall size.

    Yes, seen it blooming last spring, quite a sight, remember commenting that it looked close to 70' { 23m.} across at the time, owner smiled and nodded. Didn't seem all that tall, but spreading. Could easily be about 75-90 years old or more as the present owner's family has been growing there as a retail nursery for near 90 years. A few young trees there, which are likely seedlings from the large one. Will try to get a more accurate sizing and maybe a photo.

    Both size and age could be noteworthy.

    Don't think he's ever sized it up closely. May get a chance to find out size, age and who planted it within the next week.

    Hi Alex, would you know about what age is your tree and was it grown from seed or a cutting ? Seems they are variable to blooming age and bract size. Very nice.

    my tree are propagate by cutting ,flower after 8/9 year , propagate by seed is easy
    but if not cut a little the seed this not germinate,of course by seed flower after 10/12 years...

    Fruits actually have multiple embryos, and as with various other hardy trees the roots and shoots emerge at different times - with not all fruits in the same batch sprouting at the same times as one another. One method that has been advocated is placing dove tree fruits in a wire basket or similar ventilated container filled with leaf mold or other coarse, moist material and leaving them in an area where they will receive a cold treatment. Periodically the contents can be inspected for sprouting of roots, at which point those that have done so can be potted and put into a greenhouse or similar environment, for the shoots to emerge. The rest can be returned to the basket, to be checked again later (the roots come out after a cold period, the shoots in response to warmth).

    Thanks Paul. And Ron, for that fascinating info. Is the cold/warm roots/shoots thing specific to Davidia or more generally applicable?

    There's a handkerchief tree on the west side of Queen Elizabeth Park. I first noticed the seeds/fruits on the ground one winter day; then I noticed the tree.

    Thanks Alex, much sooner to blooming from cuttings than seed it seems. One here just bloomed very well this year , 17 years since germination., with just a few flowers the preceding 2 years. Another from seed and same age has yet to bloom.
