Welcome to the forums. *[img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img] *Glad you're pleased with your new plants. *Don't worry...you will find some way to sneak new plants in. *hehe
One way to positively ID p. primuliflora is that it is the only ping to form little plantlets at the end of its leaves. *Errr...you won't be able to tell that from your plant now with its rather crispy leaves, but once it grows out more you will be able to tell.
Beautiful avatar by the way!
