A couple years ago a hobbyist sent me live LFS and within the clump were what I believe to have been D. intermedia. Hold that thought.
I buy the dried LFS is bags and there is always what has been described as sedge grass that germinates, long before any sundew seeds I have sown. But I never see any stray sundews pop up from among the LFS. Has anyone gotten stray sundews from the dried material?
