Black plum trees?
My husband LOVES the dark dark purple plums. We have a small orchard....do they grow in Colorado? We live on Western Slope - Olathe the be exact
Montrose County Colorado trees and shrubs
I'm not exactly sure which specific plum you are referring to. Do you see this type in the grocery store? Here is a great article done by one of our Hort Agents on the front range. These will work here too. I have seen Elephant Heart plums here as well. Look for a warm spot, not a cold sink, to plant the trees- two is best for pollination. http://www.denverpost.com/ci_25890002/plum-perfect-growing-plums-colorado-can-be-easy
Fruit trees do require a lot of work. Here is a fact sheet on the care that is needed. http://extension.colostate.edu/topic-areas/yard-garden/backyard-orchard-stone-fruits-2-804/
