Does anyone know what kind of plant this is? (Me and my son called it Floris). This was my sons pet plant, he was quite attached to it. Also, is it normal for this kind of plant to just stop living? It was fine for a few years and then there was nothing I could do to stop it declining. I changed the soil, watered it properly and used plant food. I also tried a bunch of different places around the house but it went into decline and was no more. Any tips on keeping the next one alive would be very welcome.
