Pflanzenporträt Agave polianthiflora Gentryi, I. Richter
Abstract: Agave polianthiflora ranks among the most alluring flowering
species of all Agaves. It is rarely cultivated and described here with its

will be hardy enough for Central European gardens, at least in very favourable
sites in winter mild areas. - With 4 figures.

Arco – Eine Stadt am Gardasee mit bemerkenswerter mediterraner Flora,

make Arco a favourable spot for testing the limits of survival of exotic
plants. The arboretum and some other localities in Arco hold a long history
of botanical experiments, still visible nowadays. - With 17 figures and 1
table.
Keywords: Arboretum Arco - exotic plants - Jubaea chilensis - Persea americana
- Sequoia sempervirens - Trachycarpus fortunei
