Sophora japonica 'Pendula' - Weeping Pagoda Tree

I was aimlessly riding my bike one day and stumbled across this interesting and unique small weeping tree. Sophora is an older name but I'll stick with it for now. Trees develop a rounded to blob shape with very interested branches. Trees grow to about 15' so this one much be old.

Leaves are deciduous, alternately arranged, pinnately compound to about 10" with 7 to 15 or so leaflets. Leaflets are medium to light green, narrowly ovate to lanceolate, 1-2" long. 

Stems are green until mature. The black buds are hidden by the swollen base of the petiole.

This cultivar seems not to flower or fruit (no kidding, can't have fruit without flowers.) If it has them they are off white and pea-shaped in large clusters.

The branching is very cool, twisted branches with some grafting to one another.

 

Misidentification? Foliage wise, lots but with this habit I don't think you can find another one with leaves like these and a habit like this one.

New name: Styphnolobium japonicum

Santa Cruz - I forgot, I have to get on my bike and aimlessly take a ride. Went looking for it a year or so ago but could not find the tree or the house.

Sophora japonica - Japanese Pagoda Tree

A Japanese Pagoda tree is a rare site around here, I have seen only a few. Looking like almost all the other deciduous trees with pinnately compound leaves, it has a few distinct characteristics.  Growing quite large, the one on Sumner Dr. is very typical, reaching 50' with a broad wide spreading crown.

Usually do not develop fall color, but heck, this one did.

Leaves are deciduous, alternately arranged, pinnately compound to about 10" with 7 to 15 or so leaflets. Leaflets are medium to light green, narrowly ovate to lanceolate, 1-2" long.  

Typical of may plants in the pea family it has swollen petiole bases.

Also a bit different is the flattened petiolule (leaflet petiole) of the leaflet. You can also see some whitish hairs on the veins.

Stems are green, for a long time. Hidden under the swollen petiole base is a black bud. Not many plants have black buds.

Flowers are small pea-like, yellowish white appearing late July. Lasting only a few weeks they soon fall and cover the ground. Borne in large 12" long by 12" wide clusters.

Fruit is a bean like pod, but with distinct constrictions between each "pea" inside. Persistent through winter. Interesting but can be messy.

Native to China and Korea but not Japan .... who makes up these common names anyway, and I guess its new botanical name is Styphnolobium japonicum


Misidentification:
wow, how many plants do we have that look like this? Robinia, Tipuana, Gleditsia, Cassia, the list goes on.

Green stems, often for several years. Black bud. Fruit with constrictions between the seeds.
