|The single Grevilleas are protected with a double layer of non woven fabric. At night, with just little lighting from the streetlights, they resemble small ghosts visiting my garden.|
Usually I protect just few corners. Xerophytes, South African and few Australian plants. Even several species that in the books are quoted not to survive minus (celsius) temperature, have no troubles during normal winters in my garden. Moreover, I tried some subtropical like Hedychium coronarius. With some care, 10 cm of mulch and some branches to fix the mulch material, it survived -10°C two years ago!
|Grevillea lanigera is also a Winter flowering species. I wait a couples of weeks, than I'll disclose this 1.5 x1.m meter large flower falls.|
In most regions with mediterranean climate, snowfalls are rare. This is the reason why several species are not structurally build to compensate the weight of the snow. In some cases like Dendromecon rigida or even with Quercus suber, just few centimeters are enough to break down branches.
|Dendromecon rigida. Rigida from Latin "rigid" means rigid or stiff. Well to be "rigid" in regions with heavy snowfalls is not a positive adaptive mechanism.|
|This is even more harmful. This happened in the night despite my preventive job to reduce the volume of the branches and to fix the main branches.|
