We live in Dallas Oregon in the Willamette Valley
We are in the process of building a 60' long x 8' wide x 12' high green house out of tinted ( smoke) double walled polycarbonate on a cedar deck with drainage systems, insulated, heated, cooled and such.
Every year we spend $3500 in annuals and azealeas that don't make it as well as 10 Mac Baskets ( giant hanging baskets approx. 6' tall and 6' wide with impatiens, Wave petunias and Creeping Charlie type trails named after the town of McMinville Oregon that has these on every lamp post in town) we also plant around 300 white impatiens yearly.
This year was a VERY hard year to find 300 white impatiens and they were $3 a piece when we did, The Mac Baskets are getting less professional looking as the grower has now became huge and seems to care more about quantity than quality these days.
Will any of these live through the winter in a heated (grow lighted) greenhouse? Or do all annuals just die after so long? Can we get seeds or start new plants by cutting the old one somehow? Most of the plants are massive by now and I am guessing the baskets just get too rootbound to flourish or is this not true?
We would also like to grow some nice ornamental planter type trees and plants but our main concern is the Baskets and impatiens
