Abies koreana

  • Posted on: 14 December 2018

As observed in cultivation, this fir has cones greatly variable in color – from green to purplish- or blue-gray. The length and color of the bracts are also variable. Most commonly the cones are dark gray with some level of bluish tint as shown in this specimen photographed in the arboretum of the Polish Institute of Dendrology (Kórnik).

Genus: Abies


Cupressus sempervirens - Mediterranean Cypress

  • Posted on: 12 December 2018

Wild populations of this well-known cypress are not commonly seen. One has to travel to Crete or a few other Aegean islands, or certain places in Turkey, to mention some better known locations. When we were on our 2010 trip to Turkey and made a brief detour to enter Dilek Peninsula, we did not expect to see it.

Abies numidica

  • Posted on: 7 December 2018


This species is often confused with A. pinsapo, because the leaves on terminal branches may appear radially (especially in drier circumstances and on leading shoots). However, A. numidica has pectinately outspreading, longer, flat, shiny, dark green needles on the shade branches, while the needles of A. pinsapo are radially outspreading, short, cylindrical, gray, and sharper.



Juniperus drupacea - Syrian Juniper

  • Posted on: 5 December 2018

Despite its name, most populations of this distinctive juniper are found in southern Asia Minor (Turkey) and only smaller stands or scattered individuals in Lebanon and Syria. One outlying population is also present in Europe – on southern (mainland) Greece, very briefly discussed below.

Abies recurvata

  • Posted on: 30 November 2018

An easily recognized species, in spite that the plants vary in foliage color (usually shiny green but sometimes silvery gray above with dense stoma-lines) as well as in cone color (medium gray to intense blue-gray). The cones are small, with a maximum length of 8 cm but usually in the 5-6 cm range.


Torreya jackii - Weeping Torreya

During a visit to China many years ago we documented a cultivated plant of Torreya jackii for our Dendrological Atlas project. It was more than clear that this is a most distinctive species not only in the genus, but also in comparison with a broader circle of conifers.

The only temperate-zone species of the genus, this Araucaria is amongst the most unique species of all conifers. Found in the scenic environments of southern Chile and Argentina, it is quite often associated with showy volcanoes and forms strikingly interesting open stands or thick forests, usually with species of Nothofagus.
