Trees of the Year: buckthorn and alder buckthorn

Buckthorn
 
Buckthorn; European buckthorn    Harilik türnpuu          Rhamnus catharticus
 
Alder buckthorn      Harilik paakspuu       Frangula alnus
 
The initiative to choose a ”tree of the year” came from professor Viktor Masing, and the venture started in 1996 in journal „Eesti Loodus“.
 
The buckthorn is not very well known, and it is confused with the alder buckthorn, or the other way about. It grows in dry alvar areas in North and West Estonia; there we see them more often than elsewhere.
 
Despite the "puu“, meaning tree, in the Estonian names they both usually grow as dense shrubs. On the buckthorn the distinctive spines sticking out in the tips of twigs show well just now. The fruits are berry-like drupes, black and small, with 2 to 4 seeds. The taste is bitter and disgusting, and they are weakly poisonous.
 
Compared to the alder buckthorn fruits, the fruits of the buckthorn are quite poisonous and a part of them stay reddish, without turning black. Compare the photos: the leaves are quite similar, and on the north-western coast they can sometimes grow side by side.
 
We will certainly present the trees of the year more in detail when spring progresses.
