Designed to do exceptionally well in the Mountain Areas of the U.S. and Canada. This mix contains 23 species, 45% annual and 55% biennials or perennials which means this mix will give color the first year and prosper for many following years. Many of these varieties do very well in higher elevations with limited moisture. The Mountain Wildflower Mix will reach a height of approximately 36 to 48 inches under normal conditions. 1 grams is enough seed for a small flower patch 10-20 square feet in dimension.
