Does anyone know if the following can be grown in Colorado, in the Denver
area?

shamrocks ( like they grow in Ireland? ) They require cool days and moist
soil. We live in an arid climate and are currently under water restrictions for
drought.

almonds Require a more temperate climate, although Flowering almonds (Prunus
triloba) are grown here sucessfully as ornamentals.
cashews Normally grown in hot, sub-tropical climates and require acidic soil.
The soil along the front range is alkaline.
rattan Is a member of the palm family and requires a tropical setting to
succeed.
blueberries Not very easily, but it can be done. They prefer acidic soil and
ours is alkaline. Try serviceberry instead. See:
