We were fortunate in SW Michigan this summer. Temps were between 70 & 85 with lots of sunshine! I placed almost all my plants on the southern porch exposure for the second half of the summer where they received roughly 6 1/2 hours direct sun everyday. This was by far one of the best growing seasons I've experienced in some time. My VFTs are still closing quickly and producing the largest traps of the season as I write. This will all be coming to an end this weekend as we're finally expecting temps to begin dipping into the 40s saturday night. My purpurea ssp.purpurea have all stopped actve growth and are turning a beautiful deep purple. The hybrid pitchers are producing the best growth of the year like the flytraps.
