Plant ID - type of Hypericum

mudsnake(8B)August 23, 2008

I know that this plant is a St. John's Wort, in the genus Hypericum, but I do not know the species. It grows wild here in North Florida.

Here is a link to some photos. To enlarge a photo, click on it.

Can anyone identify this?

Check out the link below and scan down to the maps and check out by clicking on the map of those species that are shaded for Florida-really quite a few.

Note that not all of the plants on the link to USDA are native, the blue shading indicates native. For example, Hypericum perforatum is not native (but luckily I don't think that is what you have based on the flower).

Happily I stumbled across this plant while looking for other opposite leaf yellow flowering plants. I think it may be your plant!

Carol23, thanks for the link. That looks very much like my plant. My plant is 3 to 4 feet tall, and Ascyrum hypercoides gets to be about 18 inches tall. However, it might get taller in North Florida.

Also, thanks to terrestial_man for the link to the Hypericum page at USDA, and the tip from esh_ga.

There is another 4-petaled Hypericum species, along with St. Andrew's Cross, that is native to FL.
You will probably need to examine plant habit, stature, foliage and bark, to determine which one you have.

Hypericum tetrapetalum

Perhaps it behaves differently in FL, but Hypericum hypericoides grows 3-3.5 feet tall here in Tennessee.
