The winter hardiness of irises in zone 5 depends on the iris variety you have. Many varieties are hardy and will do well planted in the ground. However, they need to be planted in the ground by the end of July so that they can develop a strong enough root system before the winter sets in. For now, it's probably best to store the rhizome until next year.
