Hello! New to gardening and unable to identify this seedling or weedling. Hoping it will be more obvious to seasoned gardeners. Mixed local soil with some purchased growing soil and these popped up in a few of my seed trays: cucumbers, butternut squash, and tomatoes.

Thanks for any info!

Looks kind of like Cerastium fontanum (common mouse-ear chickweed). But then again, common chickweed (or at least the chickweed I've observed) tends to creep. I could be wrong though.

These young leaves are already quite long (about 1 1/2 inch already). The chickweed's leaves seemed small in the ID book I have, but upon searching more images online it does seem possible. Thanks for the lead!

Let it grow a few more leaves then post more pictures. Someone will name it.

It reminds me of Borage.

Same here.
