The ASU Seed Library is stocked with edible plant and herb seeds which are appropriate for Arizona growing conditions and seasons. At times, a limited amount of seeds from nonedible plants may be available, such as wildflowers. Seed donations are always welcome!  

• The Seed Library is housed in a repurposed card catalog, which is located in the Design and the Arts Library (810 S. Forest Mall, Tempe, AZ 85281). 
• ASU affiliates may use the Seed Library. 
• ASU affiliates are welcome to check-out up to five seed packets per calendar month from the Seed Library.  
• To check-out a seed packet, simply fill-out our checkout form which is located atop the aforementioned card catalog. 
• As you look through our collection, you’ll discover that the Seed Library is comprised of a wide variety of plant seeds, including culinary herbs.
• At this time, there is not an option to place a reserve on seed packets and all seeds are subject to availability. 

After you’ve filled-out the checkout form, you are all set! Bring your seeds home or to a community garden and start growing.
