How many stems of flowers did Lara give to her grandma? ** Lara gave 15 + 6 = <<15+6=21>>21 stems of flowers to her grandma.
How many stems of flowers did Lara give away? ** She gave away 21 + 15 = <<21+15=36>>36 stems of flowers.
How many stems of flowers did Lara put in the vase? ** Therefore, Lara put 52 - 36 = <<52-36=16>>16 stems of flowers in the vase.
