Or there can be trades set up for acquisition of Certain sempervivum so that there can be data gathered for growers in different zones and climate? Are you factoring in the initial sources or age of colony/plant.
Experiment 1: variability of sempervivum seasonal color across [defined territory] in North America (USA and Canada)
Lets say there are 12 variable sempervivum you want growing data. Define those plants and select growers. Define x amount of growers in Certain territories based on region, climate or zone. Establish a trade for growers if plant is missing from collection or of questionable identity. Set dates for photograph time, at least data gathered once per season. This is reminding me of volunteer work and science fair projects and papers.
