I ordered some plants from Hirt's Nursery once. They came in tiny cells, like 1.5 inch square by 2 inches deep.
The surface was covered very tightly with moss.
At first I thought it was a cool way to keep potted plants from shedding soil during shipping - the moss held the soil surface together.
Then I realized it was just sloppy: the surface also had strands of grass and weeds in amongst the moss. They had just pulled up clumps of soil with seedlings (or cuttings) from a very unweeded bed and shipped wherever came out.
Plus, they had advertised Lavatera thuringiaca var. 'Barnsley', a valuable "periclinal chimaera" but sent L.thuringiaca var. 'Rosea', the most common and cheapest variety.
Maybe it reverted to the non-chimaera form, but it sure reverted before even one 'Barnsley' flower showed itself.
