I was thinking, there's a ton of rooftop space on top of nyc apartment buildings, and it's often pretty easy to get onto the roofs. Are there any potted plants i can leave up there that need zero care and are good for local pollinators or native wildlife or whatever?

They'd need to be small and light enough to climb up with.

Ideas?

Well if you want to really help pollinators putting in a little more care than zero will pay big dividends.

I'd say build or buy a planter, 4' ish or smaller, lug some good dirt up, and use an ollas in the center. An ollas is an unglazed terracotta pot that you bury in the centerof the planter with the spout sticking above the dirt. then fill with water once or twice a week or so and the water slowly leeches out and waters the planter.

Pick out any plant that flowers that you like thats labeled as a perrenial and full sun. Some will be labeled as pollinator friendly. But the bees in my area go nuts for anything, cucumber pepper I had a hummer go for bell pepper flowers once.

Get like 4-6 plants for a 4' planter, depending on how big they get. Plant em. Water em real good for two weeks to get the roots established. Like every day water em for two weeks. Then you can go to using just the ollas every so offen and some extra water in heat waves. After 4-6 months sprinkle in some fertilizer to help keep the nutrients in the soil good.

Over winter, take the ollas out to avoid a freeze. Put back in spring. Probably a 2L ollas or small is all you need.

If you really can't be bothered, try hardy hens and chicks. They are small plants that come in lots of variety and make small baby plants. You can pinch off a baby plant and stick it in a random rockwall and it will probably survive. They aren't gonna help a pollinator though, more ornamental. Or get into cactuses.

I think OP’s is planning on distributing these on roofs they don’t live under.
