I guess telling the difference between D. spatulata and Drosera spathulata is sort of a CP rite of passage. It is D. spatulata, not D. spathulata. This all depends on the original author who used D. spatulata for the Drosera species, and the author of Nepenthes spathulata who included the "h". Both are correct Latin terms, but the First Word by an author, or Protolouge as they are called is what determines the spelling for all time.
Most Drosera remain largely unaffected by flowering. I have sometimes wished that my D. spatulata would flower themselves to death, lol. No, just kidding. I love them too!
Other species do prove to be more sensitive. I don't allow many of my South African species to continually flower, they often exhaust themselves if I do and it takes months for them to recover. So , once I have the insurance seed I need to keep the species going should I lose it, I generally nip the other scapes, leaving an occasional scape so I can appreciate the flowers.
I let all my D. binata flower. They are hedges now that are totally unaffected by flowering, most in gallon sized pots. The flowers are very pretty. I also let my Dionaea flower, and I have never lost any plants in doing so, although they do need some recovery time to return to their full growth.
