Would you believe it is available through Amazon.com? I was surprised, too!
The source is Hirt's Gardens, and it's expensive. But that is the only source I could find.

I hope you have not ordered yet. What is considered Cuban oregano is generally Plectranthus amboinicus which is not what is being sold at Hirts. P. amoinicus is proporgated by cuttings not seeds.

cuttings...i've not have much luck with that. where would be the best place to purchase it. i'm interested in both variegated and non-variegated. how about spanish thyme (smaller leaves), are they only propagated from cuttings as well...

a thank you to you both. i appreciate the response.

Did you got Cuban Oregano?
