Gardeners' Notes:

I have quite a few bird planted trees on a fencerow. They are very happy in Zone 8a heavy black clay. They do just fine on rainwater only. They provide a nice dappled shade and have not shown any problems in the seven years that they have been growing here. I have noticed a few seedlings, but they are easy to pull if you dont want them. The spring flowers are pollinator magnets.

A soapberry tree came with the house (a little too close to the house if truth be told). It took sending a sample to the Univ. SC Herbarium for me to figure out what it is, it being quite unusual here. I love it. Great form (like a smaller version of Chinese pistache). Nice, but not outstanding fall color (yellow). Little mess. Attractive and unusual fruit. The only negative is that it sends up water sprouts from the horizontal limbs.

This plant is taking over my goat pasture and since it can be toxic, I'm trying to get rid of it, without much luck. Help!! To those of you who want some-ya'll come and get it.

I am growing several of these from seed. I soaked them in warm water for a day, rubbed off the outer, wrinkly membrane, scratched them on the concrete, just enough so I could see a tiny dot of white from the embryo, then soaked them in water for another 2 days....half I put in a wet paper towel in a baggie on top of the fridge, the other half I put into 4-inch pots in the sun, mostly covered with dirt. About 50% are coming up within days of scarification, both in the pots and in the baggie.

This plant is a tree that spreads by rhizomes and will form a thicket. Very drought resistant, but invasive in moist areas.

This tree was one of the stepping stones to my botanical passion. There is one growing on a road that used to be a good bike shortcut when I was a kid. I saw this tree and noted it's hard-to-define texture. It has more leaflets (in even numbers, not ending in a single leaf.) than an ash (a Very overused tree) and does not look like a willow. I also noticed the setting sun shining through the transparent dried amber fruits, and these glowed like little lights.

The tree I know of is very spherical and 20-30 feet tall. It is on the fenceline of an antique house that has never seemed to have residents to water the yard. -Very drought tolerant in our alkaline clay soil. There may be another one half it's size nearby, but beyond that, they exist alone. They are old enough ... read more

Another common name for this plant is Jaboncillo. I have not grown this plant so I am unable to give it a rating. Some people call it a "trash tree". In its natural habitat, I find it quite attractive all year. Containing a soaplike substance called saponin, a natural detergent, the fruits have been used as a substitute for soap. The soap is obtained from the fruit by rubbing the fruit in water and is used in Mexico for washing clothes. The fruit can be dried and stored for later use. Some people sustain a skin rash from this substance so be careful if using the fruit for this purpose.. The fruits are poisonous and should not be eaten. Sapindus in Latin means "soap of the Indes" and saponaria refers to the saponin found in the fruit; drummondii honors Thomas Drummond, who collected plants... read more
