I had a terrible time getting an herb bed going. Herbs love dry heat and dry soil and my whole garden is a bog most of the year.
Despite being planted in damp clay this oregano has wintered over and is about a year old now.
Dominican oregano tends to be more upright than most. It has small flowers in the spring.
Oregano can reach 3′ tall, this plant seems to be content at about a foot tall and a foot across.
I could find almost no information on this plant, which is a shame. It is such an easy grower and not the least bit invasive as herbs can be.
Shortly after this photo was taken I gave it a solid pruning, removing about half of its height. Herbs in general do well with heavy handed pruning.
If you are looking for an easy oregano try this one.
I lost this plant to unknown causes.
