Share Online Resources/Data Collections

Everyone here is always asking for information on the horticultural side of things, much of which has already been extensively researched in the past.
That doesn't help us if we don't know where to find it, though.

Let's help out by collecting links to the resources and data we come across online in one spot for easy access.
I suspect there will be a number of internal BNut links to the Resources section, and that's fine. The point is to establish a library of sorts here that questions might be directed to so we can get better answers faster.
Much the same way someone started collecting links to all the progression threads at one time.

The site i recently found that made me think of this idea.

Plantmaps - Hardiness Zone Maps, First and Last Frost Dates and Much More

A Collection of Planting Zone Maps, Hardiness Zone Maps and Climatology Data for Gardening and Horticulture

www.plantmaps.com

Contains maps of USDA growing zones around the world, tree/plant native range maps, etc.
Somehow it never popped up for me before, but I found it very useful the past day or two for cross referencing native range and growing zones to infer the dormancy needs of pinus pinea. Seems to be a shortage of information on that sort of thing outside of orcharding species.
