Seed Sources

Mesa Garden: This is where I purchase the majority of my cactus seeds.

Three Deserts on Etsy: This is Rob Romero's online shop.  I've purchased cactus seeds from him multiple times.  He's a great seller.

Bakersuccs: This is Adam Baker's online shop.  He is the Astrophytum king!  He was featured on Cactus Quest's channel here.

CACSS Seed Depot: An affordable source of seeds if you live in Arizona and are a member of the Central Arizona Cactus and Succulent Society.  Join the CACSS!

My plants:  Mature plants of flowering age are not only beautiful but also produce seeds.  Keep in mind that some species are self-fertile and some are self-sterile.  For the latter, you'll need two plants to produce seed.

Cactus friends: Make cactus friends!  Cactus friends often gift or trade seeds with other cactus friends.  Instagram is a great place to meet like minded cactus lovers.
