  1. Hi, not really a regular wants subject as no sales are involved so I placed it here (feel free to move if needed moderators). A friend of mine got a request asking if he could help getting some nepenthes seeds to be used in a trial. As he doesn't grow Nepenthes anymore and I never did I thought I'd post the question here: anyone able and willing to donate fresh nepenthes seeds for some research? Species or hybrid, that's not relevant for the trial, being fresh and viable obviously is Any help would be appriciated. (please send PM)

    Drosera Magnifica In Cultivation

    @Richard BunnThe seeds got distributed with the request to learn how to grow them and get them out in cultivation so no poaching of this plant would ever be needed. People got selected for knowing their dews and some are commercial parties like Kamil with the skill to produce relatively many plants by TC. Others grow from seed and that takes longer. Finding things out means exactly that. As this species is completely new to cultivation we needed to find out temperarue, light, soil mix, does it need GA3, etc, etc. Stuff like that is being written up and will appear in CPN. As for others planning to sell..that is up to them as it is up to them if they want to be identified. The growers are everywhere,: America (I mean the continent, not just one country), Europe, Africa, Australia so wide distribution. As it obivious from these posts that I'm one of them: I don't sell them. I chose to give them to people (and a BG) who are likely to keep it alive and to be an flowering adult with the pointers we found and are still finding and thus will get it in cultivation that way.

    Drosera Magnifica In Cultivation

    @Dieball never got below around 60 - 70% @Richard Bunn@Sheila LittleNo use looking for seeds. All legally collected seeds got send to and are used by specialists around the world (including UK) for exactly the purpose of finding things out. Non of those plants is near flowering size for some years.

    Drosera Magnifica In Cultivation

    In trials damage occured at 30 C. I have daytemperature at about 22-24 and night 18 -20 or so

    Drosera Magnifica In Cultivation

    seed raised is a bit slower than TC. Sean is right about it not liking heat. Also doesn't like wet feet, so proper drainage and give it lots of light.
  6. If you are in to South African species you have probably ordered at some time from Silverhill Seeds or grow a plant somebody else once ordered there. The owners of this company Rod and Rachel Saunders got murdered in South Africa. Rod was found in February, now Rachels body has been found too.

    Carnivorous Plants In Amsterdam

    Not much in Amsterdam itself. Flowermarket near Munt has regularly nice plants for sale. For living collection quality you would need to go to Leiden. Something like 40 minutes by train and than 10 minute walk or public transport for a couple of stops. The Botanical gardens (Hortus botanicus) have a great collection of especially Nepenthes. Good antplant collection too.

    Petiolaris Germination Question

    Not so much bound by time of year. You will see your plants go into dormancy. In general I keep light and temperature the same but reduce the amount of water so they stand dry for a couple of days and then give a little...seems to work ok.

    Petiolaris Germination Question

    heat and humidty won't do any harm as long as you have enough light

    Petiolaris Germination Question

    I usually wait with picking out seedlings until they are at least 1 cm tall, better if there is space 2 cm. I accept that I will loose late germinating seeds at some point, though generally I carefully pick out the big ones, rest I let grow on which give some seeds a change to germinate. The holes in the soil generally don't pose a problem. Slime is probably algae and it can kill your plants, so I would deal with it.
