    HC and UG as house plants?

    Hi all, I'm not sure that would suit U. graminifolia, but there are Utricularia spp. (Bladderworts) that can be grown on a <"window-sill">. Just hit and miss for me, <"other than U. gibba">. cheers Darrel

    Hi all, I had Utricularia graminifolia <"for a while">, I don't have it now. I've found the difficulty with all the Utricularia spp. I've grown is that they have all (other U. gibba) suffered from "Boom then bust". cheers Darrel

    Hi all, I think it might be another species of Utricularia, <"Utricularia pubescens">, which is tiny and has peltate leaves, and that would be my guess. Typical, just seen @zozo's reply and I think he is right. New one for me too. cheers Darrel

    Mosses that do or don't attach to Hardscapes!

    Hi all, It isn't necessarily the method of attachment, it is just the frequency of trimming. Naturally pretty much all pleurocarpous mosses will grow long shoots, a bit like a stem plant, you need to prune them to keep them bushy. cheers Darrel

    Aphids in dry start.

    Hi all, Springtails are a good thing. They could be, but I think they are aphids. It is easy to tell, springtails hop if you disturb them, aphids won't as they are "plumbed in" to the plant phloem. Partially why I think they are aphids is that springtails don't usually come out when the lights...

    Hi all, I'm prettty sure if you take a submerged one and place it out of the water it will just crisp whatever you do. Have a look at <"Something dense for the back"> for some ordinary Aubias barteri, that have grown emersed under their own steam. Is a good suggestion. cheers Darrel

    Hemianthus callitrichoides flowers
