Many vegetables like lettuce, carrots, and broccoli don't have botanical origins or cultural roots in the Great Southwest, and thus are not a part of our seed-bank collection. To accommodate interest in growing them, NS/S offers selected heirloom seed varieties from outside of our region. We have chosen varieties that are relatively heat and drought tolerant, or that have a shorter growing season, so they are more adaptable to growing in the Southwest. As much as possible, we purchase from sources that produce seed organically and/or using sustainable agricultural practices. Organically grown seeds are tagged as such on their pages. When you purchase any seed or product from Native Seeds/SEARCH you financially support our work of conserving the NS/S treasure of regional heirloom seeds.
