Brilliant and cheerful strings of yellow flowers drape down from the branches of the golden chaintree in late spring. It is a delightful, spreading small deciduous tree from southern Europe (France to Croatia). In spring the newly emerging leaves are hairy and gray-green and eventually expand to the mature dark green color. There are three oval leaflets on each compound, trifoliate leaf. By late spring the sparsely-spaced branches are loaded with bright yellow pea-like blossoms that dangle together in variable-length strings (racemes). Small pods of toxic seeds follow if the blossoms were pollinated by bees.
Plant golden chaintree in a full to partial sun situation in any average, fertile garden soil with good drainage. Holding its sparse branches quite upright, it has a tendency to drop or abort its lowest ones. It will perform much better in gardens that are not hot in the summer, including having more long-lasting blossoms. In regions with great temperature variation between winter and summer this tree will likely be short-lived. Remove seedpods as they form so the tree focuses its energy on leaf and stem growth. Grow it as a specimen tree or as part of the mixed border or a residential foundation planting. (info source: learn2grow.com)

|Germination||1. Pour boiling water over the seed and allow it to soak for 5 minutes.|
2. Loosen and turn the soil on the planting site with a shovel in a circle that is roughly 2 feet in diameter and 8 inches deep. Remove any plants and roots, rocks or other debris that you encounter as you dig. Rake the soil smooth when you are done.
3. Plant the seed 1/4 inch deep.
4. Place a slow-running hose near the seed and water the soil until the planting area is moist to a depth of 8 inches.
5. Cover the planting area with a 2- to 3-inch layer of organic mulch. Scoop away the mulch directly over the seed.
