I have admired these trees for years, and when I decided to put two new shade trees in my front yard several years ago this is what I chose to plant. They have both grown very quickly and do provide excellent afternoon shade for our west facing house. Unfortunately, what I didn't realize beforehand is how extremely messy the tree is. From the time it first begins flowering (in mid summer in my area) there is a constant litter of yellow flowers on the ground. It is now almost October and the flowering continues with no end in sight. If this was occurring out in the garden, I would welcome the display but, unfortunately, the messiest of the two trees was planted a few feet from my driveway and my front porch. This results in flowers (and probably pollen as well) constantly entering our... read more

Just wanted to let you know that this tree is also growing in Newville, Alabama (just north of Dothan, AL.).

This tree is growing at California State University, Long Beach, in the engineering building parking lot and by the Japanese Gardens.

I've read that this plant is often associated with the Jadera bug.

I live in Glendora, California. We are in Southern California. For many years, I have noticed this particular tree growing across the street from my house. I always seem to pay attention to it more in the late fall when the "blooms", which actually are the seed pods, are in their full production. Usually, the tree has bothered me because the color of these pods fades rather quickly from a pink to a salmon color. They tend to stay on the tree a long time,and I prefer "true" or brilliant colored things. So,you can almost say I get annoyed when the pods linger. Recently, we had a major Santa Ana windstorm which caused millions of dollars in damage to several local communities.I was amazed that this tree, who nobody seemed to know the botanical name of,
survived the storm and the pods w... read more

Koelreuteria bipinnata can be distinguished from Koelreuteria paniculata by the bipinnately compound leaves with entire or finely toothed leaflets, flowers with 4 petals and elliptically shaped fruits. The seedpod bracts change from pink to salmon. Koelreuteria paniculata has once pinnately to a few imperfectly bipinnately compound leaves, coarsely toothed to lobed leaflets, 5-petaled flowers and conically shaped fruits. Koelreuteria elegans differs from K. bipinnata by its being evergreen, having tighter inflorescences and having leaflets with very oblique bases.

I have seen the plant growing as an avenue tree in La jolla sandiego. Infall with its coloured pods and green foliage the plant is attractive.

A drought hardy tree in Zone 10a New Delhi, Koelreuteria Bipinnata is also known as the golden 'Pride of India' tree. (Another more well-known Pride of India tree is the Crepe Myrtle-- Lagerstroemia Indica and Lagerstroemia Flos Regina that have pink and mauve flowers respectively. The L.Thorelii also has pink flowers.).

Fairly fast growing, Koelreuteria has beautiful panicles of small yellow flowers late summer through October, and the fruit capsules that follow are papery pinkish red lantern shapes that stay on the tree a long time also looking like flowers from a distance.

Koelreuteria bipinnata is a very nice shady tree that grows to over 30 feet with an equivalent spread. I am planting one at the parking lot at my farmhouse near two Spathodeas.Technic... read more

The Golden rain tree has beautiful bright yellow blooms but here it is and extremely slow grower. Which would be good if you were looking for a specimen tree which stays compact.
