My impatiens were virused last season.I dont intend to use them for awhile,maybe a couple of years.
After I bought and planted mine there was a mention of the virus on ATP. Mine looked good after a couple of month in the ground, then stuff happened. There was no great display that fall late Aug thru late September.
