All of the above seedlings have 'Scarlet Moss' as a parent. The mossing
on the seedling to the left is very soft
to the touch, while the mossing is more "prickly" from left to right
(the pink bud to the far right is a non-mossed seedling
from a different cross). Mr. Ralph Moore brought the moss characteristic into modern repeat blooming roses.
See article
about how he did it.
