witam,
na stronie The United States National Arboretum znalazlem uaktualnienie spisu roslin wskaznikowych dla stref USDA. Ponizej wkleilem spis najbardziej nas interesujacych roslin wskaznikowych dla strefy 5,6,7 i 8. Mam troche watpliwosci w kilku miejscach, jednak mam tez swiadomosc tego, ze spis ten zostal sporzadzony na innym kontynencie. Np ja przerzucilbym Nandina domestica ze strefy 6 do sterfy 7.Moze by tak zmodyfikowac te liste na podstawie naszych obsewacji? ;-)
btw. Ciekawe to z Melia azedarach - pamietam jak jeszcze o niej mowilismy. Przydzielono jej zaskakujaco niska strefe 7b, ale chyba nikt z forum jeszcze tego nie zweryfikowal u siebie w ogrodzie.
