I bought 6 perennial grasses on August 17, 2014 and only 3 of them survived the winter. I kept my receipt but when I inquired about their warranty I was told the warranty goes until December 31st of the year in which the plant(s) were purchased. Sheridan Nurseries has a 2 year warranty on their perennials, so I think you can figure out where I will be purchasing my plants from now on. I am out $75.00 plus tax on these plants. I'm very disappointed with Terra for having such a poor warranty on their plants. This was my first purchase from them and it is also my last purchase. So buyer beware.
