Here are a couple new plants I am anxious to try: Scutellaria and Eriogonum. Scutellaria was developed through Colorado State University's Plant Select Program.
Eriogonum through High Counry Gardens.
What I love about both of these is that they are developed specifically for our area and climate. That means these plants are very drought resistant, resilient against most diseases and insects here, and they ideally keep their bloom the entire season. Win-win-win. Oh, and most importantly (duh) they are unique and very pretty.
