I'm technically within the "Perennial" zone for PFG, but we had several unusually cold days this year. My question is when I might be able to tell if my PFG is coming back, or if I should just dig it out now and replace it? Also, last year I planted too much- it got WAY too big around my pool- so I need suggestions on companion plants! We have a lagoon style pool, and I HATE the tropical look when we're not in a tropical zone! (This is Houston, not Boca!)
