Help with a Dicentra Burning Heart?

I bought the bulb a couple of months ago and it did really well, so much so that it started to put out tiny flowers but in the past week almost the whole plant foliage has wilted. It gets about 6 hours of full sun light in the morning and I keep it well watered. Do i need to move it to a more shaded area? Will it come back? I have read on line that they go dormant in the summer so is this what it's doing? Thanks
