Perennial Leaflets-- by State
Dr. Leonard P. Perry, Extension Professor, University of
Vermont
The following leaflets are those from various universities and botanic
gardens which relate 
specifically
to perennials. They are listed by state, and grouped by US
or Canada. Those marked with (pdf) require Adobe
Acrobat Reader to view. Other leaflets may be found under Other
Perennial Web Sites. Many leaflets may be applicable to your
state, even though not originating there. Publications and sites have all
been checked by a real person (Dr. Leonard Perry, Univ. VT), and chosen
for ones most relevant to "perennial gardening". This list is by no means
complete, so click on each bold state name for its Extension publications,
OR if the links to publications in that state have changed.
