Okaay, so you got me curious on how to make this, so I fiddled around with it and came out with a pot leaf granny rectangle!
Sorry it isn't a square, but maybe you could figure how to make it a little wider?
Ch 3 and slip st. into the 1st ch to make a circle
Ch 2. 1 dc into circle. Ch 1 (Now, I know what I'm going to describe is probably
some well known stitch, but I don't know it, so bear with me!) Yo, insert hook into center, yo and pull it through, yo pull through 2 loops, repeat it again, yo and pull through 2 loops, yo pull through 2 loops. (Basically make half of a double crochet, interrupt with making another half of a double crochet and then sort of finish them off)
Do the same thing as before, but this time, it's 3 triple crochets rather than 2 doubles, for the middle leaf.
Ch 2 Do your janky 2 double crochets again
Ch 1 do another of the weird stitch
Ch 1 do 1 regular double crochet into the center (the stem)
Ch 1 and slip stitch to the 2nd chain you made.
Jeez, I really hope that made some sort of sense :/
2nd row (You should have something that sort of looks like a leaf now)
Do clusters of 3, chaining 1 inbetween each of the clusters. 2 clusters in the corners, like a regular granny square, the corners are the bigger spaces right before and after the big leaf and before and after the stem. You'll end up with sides that are longer by 1 cluster than the tops. "
I'll attatch my pics when my camera batteries are charged, hope that helped!
