Question -   Can you tell me some of the plants for the long day
plants, short day plants, and day neutral plants?
-----------------
The days are short in the spring and fall, so any plant that blooms then is a short 
day plant.  For example:  daffodils and tulips and crysanthemums.  Long day plants are 
those that bloom in the summer, ie. daylilies, phlox, black eyed susans, coneflower.  
Day neutral plants bloom at any time.
