It looks like my Drosera capillaris "Pasco Giant" x rotundifolia "Evergrow" croaked like the froggy here. It was growing like gangbusters then a week or so ago the leaves except the crown just dried up. I thought it had gone dormant for some reason, both D. capillaris & D. rotundifolia often go into brief periods of semi-dormancy.
Yesterday I noticed the crown was shriveling and turning brown. The plant was on a west facing windowsill and I think the roots got cooked during the unusual hot weather we had a week or two ago.
