PF is Plant Files on the other garden site.
I was on it a lot to find true colors of plants and blooms,also to see what size and shape a plant was with respect to other plants around it.
As we know the bloom colors on a vendors website are sometimes altered.
I am submitting as many photos as I can find to ATP database remembering how important the info is to newbies.
Our database is new but I am finding just as many blank spots on the other site as we haveon our new site.
PF is really important because it will give a lot of info. plus a photo,ATP is the same .We need to submit as many plants as we can to ATP database.
Its a great resource for people who want to research.
