Could not tell you the names. They are probably hybrids which I know does not help the question. The emerging green leaf plant is Dodecatheon redolens-Primula fragans. I did have a database that has the names associated with pictures but not these pictures.
My interest in the semps was growing them in different media recipes derived as much as possible form local plant resources to benefit the plants with very minimal inputs mimicking as close to nature as possible the tire container. Based on observations over time each tire allowed me to try different recipes. These were maintained in a database. Found that intimate plant association could augment positive growth outcomes for the semps and these partnerships can be composed of hybrids, natives or exotics species. The partners were limited by the environment here.
