I have two mentha spicata plants. Both are newly
sprouted on one plant the edges of the leaves are smooth on the other
they are jagged, why is their a difference?
Mints usually have
dentate, serrate, to crenate leaf margins
However, the leaf margin can be variable, particularly in hybrids.
where it is recorded as irregularly serrate.
