    Memories: My parents had a 35 year old specimen in their backyard. It was perfectly shaped with older trunk growth slowly engrossing the lower limbs. The bark was mottled with a large patchwork of greys and browns. We had a hammock underneath. My parents even had their prom picture taken in front it some 25 years ago.

    Now being badly overplanted in Seattle. Some blocks have multiple individuals arranged all around in different spots, often too small for their later growth–lopping them back is not an option unless you don’t mind spoiling them.
    An older one in a Seattle park had an average crown spread of 41 feet in 1987.

    It is stated in this fact sheet that the fruits of the Kousa Dogwood are edible. This is not true, the seeds and parts of this plant are poisonus if ingested.

    Johnny, other than one site on the web, I can’t find anything else to corroborate the poisonous assertion – in fact, I’ve found the opposite. See: Can I eat the red fruits of dogwoods? from the US National Arboretum.

    The fruits on Cornus kousa are indeed edible and can be quite tasty if left to ripen. A mean stomach ache will follow eating to many of them though.

    What are the bits of pink amongst the blossoms ? The tree is gorgeous, and having a hammock beneath sounds heavenly.

    A wholesaler I use has had Japanese customers eating the fruit of a Cornus kousa ‘Norman Hadden’. They have also eaten the fruits of an Arbutus unedo. So not deadly I guess!

    Marilyn (sorry for the late reply), the pink is likely due to a colour cast in the photograph — I don’t know if that is actually there if seen in person. Unless you mean the dots in the centre of each blossom? Those are the actual parts of the flower, whereas the white parts which most assume are petals are actually bracts (leaf tissue).
