In case of some plants you can take their cuttings to multiply them. The cuttings are put in the ground directly, so you can have multiple seedlings based on one plant. You can have dozens of plants which are used for this process.
Boxwood or jasmine can both be a good example of such plant.
The term which describes such a group of plants in my language is "matecznik", which is a variation of the word mother.
What's the correct term for such a group of plants? I'm looking for the name of the group of the plants that other plants were grown from.
Edit: I found some book titles that might be close to it:
Schoeneweiss D.F. 1969. Susceptibility of evergreen hosts to the juniper blight fungus, Phomopsis juniperovora, under epidemic conditions. J. Am. Soc. Hortic. Sci. 94(6): 609-611.
Remlein-Starosta D. 2004. Pestalotiopsis associated with Erica spp ornamental plants in nurseries near Poznań- increasing problem.
Is an evergreen host or nursery a correct term for it?
