Yes, it looks like a Hypericum species. St Johns wort has no particular herby smell. There are 100s of species. The one used in herbalism is usually H perforatum which is an invasive species in some areas of the US. To see if that is the one you have hold a leaf up to a strong light. Do you see tiny holes? (Hence the botanical name)

I suggested H. perforatum on Name That Plant, where same material was also asked about.
