CONSERVATORY
The conservatory is a place for display of tropical bon-
sai. Maintaining a tropic-like environment involves
maintaining a year-round air temperature of more
than 60 degrees Fahrenheit, irrigating the trees with
warmed water, and using grow lights to help repro-
duce long, bright tropical days. The bonsai displayed
here are primarily from southern China, Taiwan, and
the tropical Americas.

trees include both evergreen and deciduous conifers,
and evergreen and deciduous broadleaf trees. Trees
that you will see in our outdoor display area include
pines, cedars, junipers, elms, maples, hornbeams, and
