Is it still in the POT and acting as you described? If it’s warm enough, get it into the ground, ASAP. You’ve got the whole summer to get her to do her thing.
If the leaves are turning ‘crispy’ that is, surprisingly, a symptom of too much water.
She’ll be much happier in the ground than in that pot. :)
If the roots look really pot-bound, make sure to take a sharp knife and make slashes, vertically, a number of times around the root ball.
