    Drosera x nagamotoi originally was created by Dr. nagamoto (who was Japanese I believe), and is a hybrid of D. anglica x D. spatulata. Plants produced were very beautiful but sterile.

    Ivan Snyder induced polyploidy in this hybrid, granting fertility to the hybrid. His experiment is detailed at:

    http://www.carnivorousplants.org/cpn...lt291Colch.htm

    Ivan told me he sent seed to Dr. Nagamoto, but sadly the gentleman had passed away some time before. Still, this is a wonderful memorial to a great researcher, and Dr. Nagamoto's family appreciated this.

    In culture the plant is quite easy, growing well and quickly from seed. Since there is temperate D. anglica in the parentage, the plant does experience a winter dormancy if placed in a natural light cycle. There are photos on the web of well developed hibernacula, but in my conditions the plant just slowed in growth. The leaves produced in the growing season became dewless, and the stipules became very long and prominent. After a couple of months, the plant resumed growth. If you have enough plants, I suggest that you try a hard winter dormancy, I think it would benefit the plant. So far the new growth on my plant is somewhat reduced, but this is typical for most droserae that have flowered and set abundant seed as this one has.

    Seed germinated fairly well without stratification, but I would advise a cold stratification to enhance the germination.

    I find this creation of Ivan's to be my favorite of his long list of "new species". You asked me privately if this plant was rare. Since it is a fairly new creation, it is very rare - especially in other countries, but it is spreading. It must be very exciting for Ivan to chart the progress of this species as it spreads through private collections around the world. The sterile D. x nagamotoi has been making the rounds since Dr. Nagamoto first made the hybrid, reproduced from leaf cuttings, and is more represented in collections, and hence may be considered less "rare".

    There is also a D. x nagamotoi tetraploid from Ivan that I have not yet experienced.

    I'll try to get a good resolution photo up here soon of this neat plant, but a smaller version may be seen on my website:

    Congratulations on your new Sundew!

    Thanks for the informing reply! I will be sure not to freeze this plant! [img]http://www.**********.com/iB_html/non-cgi/emoticons/wink.gif[/img] The greenhouse heater is working very good and besides I have a backup heater that I can now set correctly and know that the plants will be safe so hopefully no more freezes this year anymore!

    Nep G,

    A hard dormancy might really benefit it. I have not tried this myself, but it is probable....as above.

    Well, it doesn't need dormancy now but I'll be sure to try it as I was sent a few plants and 1 is always up for experimenting! [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img]

    Hi Larry,

    How interesting! This plant looks very little like mine! are the flowers of this pink? Ivan mentioned the flowers could be either. In my plants, the petals are quite ragged and deformed, and white. Also the coloration in my plant is more "maroon" and less red/green. I suppose there is some mendellian ratio that is expressed that accounts for this. It is a very nice plant you have there, and makes me want to try some more seed. If you're into swapping seed of my plant for some of yours let me know, we could see if these traits stabilize with successive generations.

    Anyone else cultivating this one? Any photos? I am very curious!
