I have planted the oregano from last year, it has grown well, but i don't think it's oregano. It has no smell of oregano and no taste. The leaves look similar but are a lighter colour than i was expecting. Could it be something else?
Oregano does best in full sun and if it is grown in partial sun, it will be less flavourful. Likewise, its flavour will be enhanced if you don't give your plant a lot of water. For better flavour and a more compact plant, thin your oregano by pinching off the flowering buds before they open. Regular picking will also encourage your plant to produce more edible leaves. Happy growing!
