Superior Herbaceous Perennials<\/span><\/b><\/span><\/p>\n

The main objectives of the PERC perennial garden are to determine which herbaceous perennials are best suited for growing in the Rocky Mountain area and to display these plants for public enjoyment and teaching purposes. The perennial garden was started in 1980 with four beds. Presently, there are twenty beds and approximately 810 different taxa grown and evaluated. Many more taxa have failed to survive for various reasons. Growth, cultural, and landscape characteristics of these plants have been observed annually, resulting in a database for evaluating their suitability for use in High Plains landscapes.<\/span><\/p>\n

Listed below are just eight plants that performed well in past years and merit more attention for use in the Rocky Mountain\/High Plains Area. You are welcome to visit PERC located in the south-west corner of Colorado State University in Fort Collins any day of the year during daylight hours. <\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/2″][vc_column_text]Acanthus hungaricus Bear’s Breeches<\/b><\/span><\/p>\n
