I took a look at FTBS's site and see that ( I would like, someday, to have one of everything Kermit.
) you have it listed as 'Purpurea' but also make reference to 'Purpurascense' ( "It is known botanically both as Salvia officinalis 'Purpurea' and Salvia officinalis 'Purpurascens'." ) There are still separate listings for each on ATP and an additional Salvia officinalis 'Purpurascens Variegata' that would seem to be improper if 'Purpurea' is correct. I submitted a photo under Salvia officinalis 'Purpurascens' because everything i could find pointed to that being the proper epithet. This prompted my initial inquiry on how/where to make data change proposal. It seems interchangeable everywhere I look. ICRS was what led me to FTBS. Perhaps there all correct?
