Hypericum
« on: October 11, 2011, 07:39:09 PM »
Seen on Akrokorinthos
In my book it looks like
Hypericum empertrifolium
However, in a list of plants of Akrokorinthos from a study by Patras University only Hypericum triquetrifolium is mentioned.
Does anyone know the difference?

This does look like H. triquetrifolium to me which is an herbaceous species with seasonal growths which have a distinct almost pyramidal growths and runs. H. empetrifolium are shrubs of varying stature depending on the subspecies.

I'd go along with that.
It is a common sight in arable fields here in summer; often it is the only plant in the field (perhaps Polygonum equisetiforme as well). As the summer wears on, the plants get darker, from a distance appearing almost burnt.
Lots of info on H. triquetrifolium at http://maltawildplants.com/CLUS/Hypericum_triquetrifolium.php,
incl. some effectiveness against nematodes (ref. Al-Askari, A.A., Stephan, Z.A., Antoon, B.G. & Obaedi, J.F.W. 'Effect of plant extracts on the control of the root-knot nematode Meloidogyne javanica'.  Iraq. J. Agric. Sci. 1990, 21: 1-12) [search the page for 'javanica'].

Hypericum empetrifolium makes a good garden plant. With garden soil an a drop of water it grows tall and handsome. Even here with its seed heads it's not at all scruffy. It's really hard to photograph though.

Hypericum empetrifolium is easily recognised when in flower, by its bright flowers in whorls of three cladding its stems.

Hypericum balearicum
« Reply #6 on: July 02, 2012, 11:00:54 PM »
Today I visited the Diomidis botanical garden (of Athens) and I ran into this shrub tagged as Hypericum balearicum. I thought to myself that this species may be an exceptional option for mediterranean gardeners. There were only a few flowers on this 1,5m height x over 2meters shrub, but the same plant should have been absolutely spectacular a few weeks ago!

I absolutely agree that the wild hypericums make ideal garden plants; the spring flowers are lovely and the seed heads carry on the interest.

I couldn't agree more on H. empetrifolium, ...such a beautiful species (it is really common on mt Hymettus). I have some photos... and I'm about to open a new thread :)
