In terms of the seed mixes, I'm admittedly not super familiar with a lot of the varieties included. I'm not sure which are annual, perennial, etc. Have to research them more. I grabbed them to add some variety.
Either way, I won't be moving till next year (assuming Covid doesn't cause massive delays...), so I can maintain things till then. Hopefully once I've moved on, they'll still be maintained and the insects can enjoy them when they're ready.
I'm still going to go get some more plants for this spring though. There's very little alive outside right now, so I wouldn't mind a few hardy plants that are blooming now to provide food for the pollinators that are already out and about.
Edit: Peeked outside a few minutes ago. There's honeybees swarming that hyacinth I brought home.
