I have no idea. I sent him a message with (hopefully) some helpful
information and asking why his message had been duplicated so many
times.
On an entirely different note, I've finally been able to identify my
"mystery pings". They are indeed P. caerulea. I'm incredibly patient
until a plant decides to bloom, and then every little thing it does
makes me jumpy. The purple flower stubbornly refused to open, then
hung facing downwards, and is now turning upwards to face the light.
Strange behavior, but as long as it's happy I'm happy.
