When should these perennials sprout?
So yesterday I posted a question about whether my delphinium should have sprouted yet (unfortunately I think it is a goner). Upon further investigation of the garden, I have a number of other questionable perennials that I am not sure are coming back.
So my question is, when do the following normally sprout:
1. Guara (Pink fountain)
2. Starburst Ice Plant (These are supposed to be hardy in Zone 5, but I read they may die if they have wet feet over the winter)
3. Agastache (hybrida 'Kiegador')
4. Vinca major 'variegata' (I originally thought this would be hardy in Zone 5, but after reading online I think it may only be Zone 6 or higher. Anyone had luck with it returning in Zone 5?)
