Looking through your catalog I noticed a lot of mentionings pertaining to zones...I live in Connecticut...Could you tell me what zone that is in?...will there be any problems that may arise or that I must look out for?

Horticulturists have divided the world into so called zones that have about the same average minimum winter temperatures.

Zone 1 has minimum winter temperatures of below minus 46 degrees Celsius (below minus 50 degrees Fahrenheit)

Zone 2 has -46 to -40 degrees Celsius (-50 to -40 degrees Fahrenheit)

Zone 3 has -40 to -35 degrees Celsius (-40 to -30 degrees Fahrenheit)

Zone 4 has -35 to -29 degrees Celsius (-30 to -20 degrees Fahrenheit)

Zone 5 has -29 to -23 degrees Celsius (-20 to -10 degrees Fahrenheit)

Zone 6 has -23 to -18 degrees Celsius (-10 to 0 degrees Fahrenheit)

Zone 7 has -18 to -12 degrees Celsius ( 0 to 10 degrees Fahrenheit)

Zone 8 has -12 to - 7 degrees Celsius ( 10 to 20 degrees Fahrenheit)

Zone 9 has - 7 to - 1 degrees Celsius ( 20 to 30 degrees Fahrenheit)

Zone 10 has -1 to 5 degrees Celsius ( 30 to 40 degrees Fahrenheit)

The rest is tropical.

First of all let me reassure you that Connecticut is slightly warmer than our own zone and anything we call a "P" for perennial will be winter hardy in your area. Connecticut, USA has zones 5 to 6 while we have zone 4 to 5 right at the location of our nursery in Goodwood, Ontario, Canada

The only problem you might have is with too much rain especially in the winter. You are in a far more coastal area with good snow cover but sometimes too much rain for desert adapted plants. Plant woolly plants where you can pop a rain shelter over them in the fall to be taken off in spring.
