The regions where the plant is considered native, how aggressive it spreads (there is some metric that captures this IIRC), and regions where it is labeled as invasive. The PictureThis app shows this info, and it's incredibly useful.

For outdoor plants, I would really want to know what plants are drought tolerant. Climate change is drastically altering summers in Minnesota (wildfire smoke, drought, high AQI, high temps, extreme downpours).

It would also be really great to search for pollinator friendly plants (https://bluethumb.org is an excellent reference)

I’ve been building a permaculture garden and I want to know

- usda hardiness zone - sun/shade tolerance - geographic origin - is it a nitrogen fixer - soil pH preference - wet/dry soil preference - when does it fruit?

This is a decent resource: https://permacultureplantdata.com/

Water usage, edible or not, color changing leaves, shade tolerance, soil compatibility, flowers or not, color of flowers.

Not sure if there's a way to say 'messiness factor'... some trees drop a lot of crap besides leaves.

It would be great to find native plants for your area.

This might be a stretch, but I would love to know what outdoor plants are native to my area.

The number one thing to know for outdoor plants is if they are invasive or not.
