    Is the reason for your flowering success outside of the greenhouses with the N. ampullaria cv. Williams Red due to the fact they are exposed to more natural conditions. Or do you baby them outside as well?

    More natural conditions I think.

    N. ampullaria in habitat grows mostly in dense peat swamp forest and seems programmed to flower when there is a sudden increase in light level coupled with a time of year (about January in my experience). Increase of light is usually either by vining to the canopy or by an event like a fallen tree allowing direct sunlight to reach the plant. By putting them outside they go from 80% shade in the nursery to 0% outside for 6 hours of the day. This causes ugly leaf burns but also flowering. One plant had 6 spikes.

    The ones outside don't get babied at all but they do get a lot of natural prey.

    Here are some photos:

    N. ampullaria growing in nursery. Nursery roof is 18' high. No flowers!





    N. ampullaria growing outdoors - many flowers.

    Hi,
    so happy to see pics of the greenhouse! very nice and neat (despite the vines)!
    And wow! William is a female ! [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_n_32.gif[/img]
    just wanted to find out, do the younger plants have extra netting? or all sit under 80% cloht? And the pots seem very small for vining amp! its filled with nothing but cocohuskchips?
    thanks

    Rob, you always make me happy [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img] And glad the Williams Red is a female, it's a change for once to have a single clone that is female. I have so many male Neps in flower at the moment, and a solitary female...

    Well, given that the 'Williams' after whom it was named was a lady, it's entirely appropriate.

    "Was"? Is there something I should know about? [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_m_32.gif[/img]

    Lam_wn, all the plants in our lowland nurseries are under 80% shaecloth and sometimes additional 50% shadecloth over tender plants in the dry season, so that would be 90% at times. There are some surrounding trees that cast shade at certain times of the day, so we place plants accordingly since species prefer a lot more light than others.

    The pots for stock plants are 30cm (12") in dia. Since N. ampullaria like to send out lateral runners (is "runners" the right word?) then it's not ideal and the entire surface of the media in the pots becomes covered in a carpet of pitchers and the whole pot one mass of roots.

    The plants outdoors are in the ground. We've never dug one up to see how the roots have gone. I wonder if that may have a bearing on the flowering situation. We'll be moving the nursery later this year so guess we will find out then.
