These pages are not intended to replace any other websites!  
They are not intended to be a study in botany, but are only 
images we gathered and things we saw and learned over a four 
year quest of finding wild, native milkweed across central 
Texas to the coast.  The pages and photos may be reproduced 
and used only for educational purposes.  The pages were 
started after we found it so difficult to locate wild, native 
milkweeds.  We designed the pages to help other teachers, 
students, and parents to locate and monitor milkweeds and 
monarch larvae during the spring, summer, and fall.  

When reproducing, we would appreciate proper credits  be
included.  Teachers, we designed the pages to print with text 
and photos on one page and then hopefully skip to the next 
page without much loss.  Any errors are ours alone!  We lose 
pages, lose photos, lose links, and make "misteaks", but hope 
the intent and content remain as we wished.  This was not a 
definitive study and changes are being made almost daily!   

Contact us about any errors.  Please protect those native 
milkweeds!   Thank you, good milkweeding,  good monarching 
from the Texas mid coast.
