I have a 5 year old Golden Chain tree ( thats what the nursery tag
said) and though it is growing each year it never has bloomed. The
tree just has two petal yellow "flowers" each spring randomly in the
foliage. I am in Ffld County ct - I have never pruned the tree.
Anyone know how to get it to bloom? Thanks, Nancy P.
While I have no firsthand experience growing Laburnum, I did see them at
the nursery at which I worked. They seem easy to please culturally, here is
what Dirr has to say about them:
"CULTURE: Transplant balled-and-burlapped or container-grown in spring as
a small tree into moist, well-drained soil; the plant is adaptable to many
situations but prefers light shade in the hot part of the day; will not
withstand standing water; also cold injury can be a problem; withstands
high pH conditions; prune after flowering; should be looked upon as a
short-lived tree in the Midwest and probably East; not at all heat
tolerant, possibly excessively high night temperatures, and therefore not
suitable for the South, although a tree in Spartanburg, SC persists;
several newly planted trees in the Milliken Arboretum have died and the
remaining plant persists by a thread."
And, as always, whenever I see Laburnum mentioned I add:
" Seeds of LABURNUM contain an alkaloid called cytisine, which can be
fatal to children and adults. This compound is contained in all parts of
the plant. Supposedly, one small seed can prove toxic to a small child.
Extreme care should be exercised when using this plant in a public area."
