Beginner Gardening: Is this a weed???, 1 by NoGreenThumbnTN

2nd Season of 'trying' to garden. The sad thing is, as green begins to come back to my garden, I don't seem to know the difference between plants and weeds.

I took pictures last year hoping that would help me to know what should come back where. Very close, but not exactly where this 'green thing' is coming up, I had 'Jethro Tull' Tickseed planted.

Is this a weed...or is my Tickseed possibly coming back?

I probably have several weeds growing, but I'm scared to pull them in case they might possibly be one of last years plants.

Help!
