Hardy Palm and Tropical Collection
At the Dallas Arboretum
Palms, among the seven oldest known flowering plant families, give a tropical
and, because of their ancestry, almost prehistoric look to a landscape.
The Dallas Arboretum’s Hardy Palm and Tropical Collection, installed in 2006
thanks to the generosity of The First Men’s Garden Club of Dallas, is designed
to inform gardeners and garden designers of the species of cold-hardy palm trees
and other tropical plants that grow well in north-central Texas. While the palms
displayed here are selected for their ornamental attributes, many species in
their native regions are valued for their economic uses. In addition to being
sources of edible fruits, seeds, and oils, palm trees provide wood for
construction and furniture, fibers for brushes and ropes, and leaf material for
thatching and basket-making.
In general, palm trees require well-drained soil high in organic matter and
abundant water in the growing season. Light requirements are noted in the
individual entries below. The species in this garden can be expected to survive
in temperatures as low as 10º F, although some leaf damage may occur in extreme
cold.
