  • Posted by ILPARW (southeast Pennsylvania - Zone 6b) on Sep 28, 2018 8:06 AM concerning plant:
    I was looking through a mail order nursery catalog that came in the mail of Kelly Nurseries out of Fairbault, Minnesota. I'm not interested in most of their small, shipped plants, unless it is hard to find I might consider it. On page 15 they are offering this Laburnum cultivar to be shipped as a 4 to 5 feet high sapling for about $30. Yes, Golden-chain-trees are rare or uncommon in the USA, though they are common in their native Europe. I've only seen one Laburnum in my lifetime that happened to be this 'Vossi.' It was planted at a retirement community in Newtown Square, Pennsylvania west of Philadelphia. It was planted as a 6 to 7 feet high young tree in 2004, originally grown in a big container, bought from some local nursery. It was upright and not full in foliage with some weeping, and it hardly grew at all for at least the decade that I saw it when I worked around there. For its size it had a good display of the hanging yellow flowers. Otherwise, it just sat there hardly growing at all. I've never seen a Laburnum in my native Chicago, IL area and I don't know of any nurseries selling any there. Morton Arboretum in Lisle, IL, has a few Laburnums planted in a few spots according to their website, but I have never seen them.
