    Hello,

    I was wondering if anyone is currently growing the Florida all red Drosera filiformis var. filiformis. I got some seed today and wanted to see some photos of the plants if possible. I also noticed that the germination instructions say no stratification needed, no dormancy needed unless the plants form a hybernacula.

    I remember reading something about the all red form, but I cannot for the life of my find it again.

    Thanks,

    Nick

    Careful where you crawl, it might be a trap!

    In my experience, seed from the red D. filiformis from Washington Co., FL requires stratification to germinate.

    I like the ICPS seedbank page on D. filiformis. Additionally, John Brittnacher posted some more information on the red variant to the international CP listserve last month.

    It kind of sounds like it should be allowed to go dormant...but maybe I am geting confused because of all the variation from seedlings.
    Forbes, you say you stratify the all red seed you have?

    Cheers,

    Joe

    Joe,

    I don't see any reason to force any plant into dormancy. All the temperate plants I've grown will go dormant in warm temperatures if and when they feel like it.

    The first time I sowed seed from the red form, I didn't perform any stratification and got no plants. I stratified the rest of the seeds for a month with good results. Seeds from different locations may behave differently. Mine are from a location different than the location that most plants in cultivation hail from, IIRC.

    Red filiformis is an odd one. Discovered by my friend, Joe Mazrimas, his first knowledge of the plant was sketchy at best. After a couple of years, he discovered that some of the plants grew year round if kept above 60 degrees F. Some of the plants went into a "normal" dormancy. The key is to keep strict observations to see in which direction the seedlings want to go at regular dormancy times, and separate the hibernacula formers from the constant growers. The non-dormant plants will not survive below 60, so don't buck the system, keep'em warm and they will filiform their hearts out for you all winter. As to Forbes' assumption about stratification, I suggest you go with it. Cold does seem to trigger growth in both ping's and this form of drosera's seed. Very beautiful fili when grown under lights for the winter.
