Dear All,
Am a new gardener having inherited a beautiful garden and this
will be the first of many posts i'm sure.
I have a large bush which is tagged Hypericum, is this St Johns Wort or are
there varities of Hypericum? It is a large bush
about 2 metres high and wide.
I assumed StJohns Wort to be a smallish herb? I have some herbs one of which
I thought was StJohns Wort, it has 5 petalled flowers though its stems
branch like a buttercups, it does not have the perforations however like
i've read it should have. The large bush does... can anyone help?

The botanical (latin) names of plants are assigned to reflect the way we
think they have descended from a common ancestor and indicate
relationships between plants. Hypericum is a genus name - within
Hypericum there are many different species, including Perforate St
John's Wort (H perforatum), Hairy SJW (H hirsutum) and similar small
native species all called St John's Wort. There's also Tutsan (H
androsaemum) which is bushy, and Rose of Sharon (H calycinum) which has
huge flowers ... your bush Hypericum may be one of these two.
