An interesting article!, I only wish I don't have to rely on Google translate!. For the benefit of English only readers,the conclusions:
'Violetta' (cultivar protected VOC): contrary to what had told me some experts who regarded his overrated hardiness, it is one of only two fig trees whose aerial part was not frozen. The cold has altered the branches of the year and the subject very well the rigors of winter.
- 'Prickly Langres': as noted earlier, also held up well; the aerial part has not frozen. However, the branches of the year and two years died, but the subject was five years old, moves from the three-year wood.
- 'Hardy Chicago', 'Dalmatia', 'Long August' and 'Golden': all the aerial part is dead, but the spring regrowth is vigorous enough from the strain.
- 'Nordland': completely frozen aerial part, and pushes more modest from the strain for the four aforementioned varieties.
- 'Pastilière': completely frozen aerial part and pushes low strain, much less vigorous than 'Nordland'.
- 'Brown Turkey': surprise for this variety. Generally considered the most cold-resistant varieties sold in nurseries, is one that has the least resilient (while the subject is placed in the most protected area of land). Aerial part completely frozen and regrowth from the strain is most disappointing. Most of rusticity that I had read previously that variety was reported by a Bulgarian nursery, in which a specimen that was bred and raised there, withstood a cold -18 ° C without any damage.
