PlantFiles: Golden Chain Tree
Laburnum anagyroides

i have had it growing now for 4 years and still no flowers. i read about shocking it but not sure if it is to late to do it this year. i already shocked it yesterday so i gess i will find out. does anyone know if it will work this year or not

I have had this tree for many years and it would not bloom until an old gardener said I should "shock" it by taking a shovel straight down into the soil. Do NOT wiggle etc. just go straight down all the way around the tree at the same distance as the branches from the trunk. Hope that makes sense. It works, I have done this every year since and we get wonderful blossoms and scents.
Love this tree, am trying to propagate some of the seeds but so far no success.

Does anyone know why the Golden Chain Tree won't bloom? I have had it for 5 years it is about 6-7 ft tall that doesn't even look like a tree more like a overgrown shrub with 5 tall limbs.

Does this plant or any of the others mentioned have a seed pod that is about a foot long and looks like a banana that has been dried to black? Someone on the streets nearby me has two in their parkway and I always admire them. One day I stopped the car and stole a long seed, and wouldn't you know, my husband tossed it, thinking it was nothing. You'd think living with a gardener and a crafter who saves everything, he would have known better. I live in San Diego and guess I'd better drive by that house again and this time go to the door and ask for a seed.

Both NCSU (http://www.ces.ncsu.edu/depts/hort/consumer/factsheets/trees...)
and MOBOT (http://www.mobot.org/gardeninghelp/plantfinder/Plant.asp?cod...)
suggest zones 5-7 for this tree, as well as for the commonly-sold Laburnum x watterii. There are other academic sources on the internet which also suggest zones 5-7 for these and also for the other two Laburnum species.

However, all Laburnums in the PlantFiles are rated for zones 5-11. Martha1Spur noted below (in 2006!) in one of the comments that people are confusing this plant with Koelreuteria paniculata, which truly has a zonal rating of 5-11. Wouldn't correction of this (on all Laburnum entries) help to decrease some of the confusion and help people to avoid wasting their money planting this tree in warmer zones?

Editor's Note
The zonal information has been updated

i don't know if this qualifies as helpful yet, but here goes anyway. i ordered 2 golden chain trees from Burgess because they were so inexpensive and i figured if they did'nt grow i would'nt be out more than the price of a hamburger. when the trees came i had to pot them because i had just sold my house and would'nt close the loan on the new place for another 6 weeks. 6 weeks later the guy backed out of the contract. now i have no house to live in and had to move into my daughters garage and put my stuff in storage while i looked for another house.in the meantime the chain trees sat in their one galloon pots along with a zillon other things i had ordered till july when i finally found a place i could live with. by now the 1 ft. trees had been attacked by bugs and were looking pretty sorry. as soon as i could i started to plant the pots , not holding out much hope for the trees because the heat index was running from 110 to 115 for weeks at a time with absolutely no rain. The ground was so hard i had to soak it with water just to dig a hole. Then, to my amazement, up from the grave they arose. From july to the first of nov. thet have grown over 4 ft. tall and are beautifully green. They havent gone through a winter yet but our winters arent to tough in central oklahoma and i'm not worried. Go figure.

If you love this tree and live in a warm or tropical area you should try growing Cassia fistula The Golden Shower tree, which loves the sun and can tolerate some drought. It is just as beautiful to look at also.

I have had a dwarf Golden Chain tree for about 17 years . I had it in a whiskey barrel for many years and it always had bloomed. About 5 years ago I transplanted it into the yard in full sun it grows beautifully but never blooms anymore. Any ideas what I can do to get it to bloom?

I just visited a 'tulip' garden in Amsterdam this past week and saw this tree with all 'bright' golden chain flowers, didn't know what it was !. I also saw this 'plant' already flowered in a small pot ( 1 gallon ) for sale at the Amsterdam flower flee market !!!. Came back to Houston (TX) I must have one to try.

People on this thread are, I think, confusing Golden Showers (cassia fistula), Golden Rain (Koelreuteria paniculata), and the Golden Chain trees (Laburnum spp). Golden Showers grows in tropical regions, Golden Rain in termperate (at least here in zone 6) and the Laburnums grow in cooler regions (at least in zones 3-6). All are great-looking trees!

The Golden Chain Tree is growing profusely in my front yard in Bar Harbor, Maine! There are many neighbors who also have it in their yards - I guess from the seeds blowing. It has just stopped blooming now (July 7th)

I just ordered a Golden Chain Tree, mainly because I think they are beautiful in bloom and they make a good shade tree.
I just read in the members threads about this tree, that it does not like tropical or sub-tropical cimates. Oddly enough, the first time I ever saw this tree in bloom was on vacation to the Florida Key's. The tree was huge and the blooms looked like they were tied to a long rope. Now I live in zone9b and there is one equally as beautiful as the one I saw in the Key's downtown. I hope I haven't made a mistatke, but if these other trees survived the sup-tropical climate, I hope mine do as well!

I have this plant in a corner, well protected from the winds from the west by the side of the house and porch. It grew from a very small seedling and is approximately 5 feet tall.

A small deciduous tree that is often trained to form archways over paths. Has yellow flowers on 60cm long racemes. Foliage opens pale green and matures to dark green. Likes fertile soil and sun. Does not like tropical or sub-tropical climates. Good points: beautiful flowers, ideal for small gardens.
Downside: snails love foliage.

Moderate grower to 20 ft. tall, 15 ft. wide.
Spectacular color from long, drooping clusters of fragrant bright yellow flowers!
Attractive deciduous garden tree planted singly in a lawn or grouped.
