Notes on Garden Conditions

Flower color:
The table aims to provide simple and accurate descriptions of flower colors, but both flower color and people's definition of terms differ. The patches of color in the table are intended to make it easier to find flowers of a given color; they are only rough approximations of individual flower colors.

Height:
Heights are given in feet ( ' ) and inches ( " ). To convert to meters, multiply feet by 0.3 or inches by 0.025.

Light:
full sun Full sun -- more than five hours of direct sun per day.
part shade Part shade -- two to five hours of direct sun, or all-day dappled sun, as from sunlight shining through open trees.
full shade Full shade -- less than two hours of direct sun per day.

Soil conditions:
"Avg." soil means average level of moisture found in our area. "Dry," here, means soil that dries fairly quickly after a rain, or soil dried out by shallow tree roots -- not desert conditions. Note that plants capable of growing in sun or shade prefer more moisture in full sun, less in shade. If a plants has requirement for soil texture and soil pH, they are noted. If you are unsure about your soil, a soil test will provide this information. Connecticut residents can get free soil testing from the
Connecticut Agricultural Experiment Station.

Hardiness zones:
These describe the plant's tolerance of winter cold. Here is one site where you can look up your hardiness zone. Connecticut is in zones 5 and 6; all plants listed are hardy throughout Connecticut.
