Same here, family tradition. Hello from Slovenia. We are also closely monitoring the situation in Italy. There are other plants that can be infected by X. fastidiosa and should be monitored for signs of disease for example here we are worried about oleander plants that were imported from South Italy.

Ditto (from Croatia).

I never understood the obsession with oleander around these parts. It's (in my humble opinion) not any prettier than "native" ornamentals, and it's toxic to boot.

Add to that list that it's apparently an eager vector for X. fastidiosa...

Olive trees are planted decoratively and for crops here, but they're messy trees to have in city neighborhoods.

The wild variety (Olea oleaster) is not as messy.
