I've come by many interesting plants over the decades. Here are some of them.

As for the plants just above, from left to right, here's where I got them:
The dark green sanseveria plants were a gift from one of my first cousins on my father's side of the family. The cousin who gave them to me called me one day in 1983 or '84, when Walt and I were living in Washington DC, and said she and her husband were going to be in DC and asked if they could come see us. Of course, I said. When they arrived, she came with this plant as a gift. She said they had been at our grandmother's bedside when she passed away a few years earlier. I've had them for all that time, and they have lived in DC, San Franciso, Silicon Valley, and now France. I think I gave some of them to Charles-Henry when we left California in 2003, and he brought me a cutting or two a year or two later when he came to visit.
The donkeytail is a sedum plant is that I found, and rescued. I was in North Carolina 20 years ago and my mother and I were browsing around in a garden center. I happened to notice a two- or three-inch branch of the plant lying on the floor. It had (been) broken off. I picked it up, put it in my shirt pocket, and brought to back to Saint-Aignan when I returned to France a few days later. It's easy to grow but hard to handle because branches break off at the slightest touch.
The plant on the right above is a cutting from a big shrub growing in the yard of one of our neighbors here in Saint-Aignan. I pinched it last September, put it in a jar of water, and the planted it in a flowerpot when it started growing roots. I have two more cuttings in a jar of water now. I hope they'll grow roots over the summer.
