I haven't sold too many houseplants but the ones I have sold in the past have more or less been price by size. My baskets of Spider Plants usually went for around $5.00 b/c I had so many.

Sorting by lighting requirements may be a good way to go that way people will know right off the bat what works best for their location.

I would price each and every plant. Some things are rarer and as such should get more. definitely price to sell.
Where will the sale be?

Thank you so much for the information. The difficult part is going to be determining which plants are rarer than others! I know plants like Spider Plants or peace lilies can be relatively common. But some bromiliads and opuntias are rare. WHats funny/strange to me, where I come from these "rare" plants are very common!
The sale is on the 20th January, in Worcester, NY at ST. Joseph's Hall. (worcester is about 50 miles from ALbnay down I-88)..
Thank you again for your replies..
Does anyone know a good indoor plant catalogue that help with the pricing?
