Preliminary observations on winter-hardy Agave spp. in Hungarian rock garden

Abstract

In the recent three decades several winter-hardy succulent collections were established in Hungary. These collections belong to winter-hardy cacti and their companion plants the agaves too. The agaves are much more rare than cacti and only few species can tolerate Hungarian climate conditions without any guard. When selecting the species, winter-hardiness has to be considered which includes all factors in the winter period. Observations were performed for frost resistant or winter-hardy Agave species in private collections. The recent paper gives information on 7 species of Agave and try to help the determination of the plants outside in the ground.
