Okay, I just received a packet of the Drosera regia seed from the ICPS seedbank. I am most determined to succeed in growing at least one of these seed to maturity.
I've germinated seed of Drosera regia about four different times through the years. I never managed to keep seedlings alive beyond about 1/2 inch tall. I've read and reread everything I can find about how to succeed at growing mature Drosera regia plants from seed. I believe that I have a better chance of success than at any earlier time.
If anyone has any tips with this endeavor, please share them here. Thank you.

Dear Joseph,
Only moderators can post in that section, so I'm posting the reply here, and later it can be merged, I think...
Do feed the seedlings. I think this will help them greatly. Many times, especially as noted in books, there is this idea these plants don't need to eat. Perhaps there are a few species out there that don't need to eat much, but most species do need to eat and consume prey on a regular basis to maintain health and vigor. D. regia have huge roots, and it probably takes a fair amount of food to get them up to size.

Thanks Dave, It sounds like I should treat Drosera regia seedlings as I treat my Drosera indica seedlings. I feed most of my CP, these days, in various ways, with mostly good to excellent results. But I quickly discovered that if I wanted Drosera indica to grow to maturity (in my lifetime), I needed to feed them early and often.

I'm learning lots here! I'm not only trying to germinate Drosera regia I'm also doing the same with D. indica. If I can get them to sprout I now plan to feed them regularly. By the way - I love the ICPS seed bank!

I just wanted to add, when feeding tiny seedlings, feeding is tricky, it only takes a tiny bit of insect or fertilizer - it is very easy to overdo it.

Of course for seedlings it will take a much lighter touch than I'm used to. Your words of caution are well placed, Joseph. I've certainly rotted leaves out in the past by overdoing it - and this was on larger plants.

Since I am at the stage where I'm just hoping for germination I would be interested in others' experiences just getting D. regia to sprout. I have read the article, though I've been unable to find it lately, that describes germinating it at California Carnivores. I now have seed sprinkled in a pot on soil about 1:1:1 of peat, sand and perlite. These are in a terrarium with a standing humidity of over 75%, the temps run from the low 60's to the mid 70's F. I keep the soil very moist and it's been under bright light, all for about two weeks now with no sign yet of any sprouts. Any suggestions?

Just a word of caution bluemax, D. regia is very prone to Damp off, in the later stags of germination. You should perhaps let the media stray to the slightly less wet side, every now and then, and have a lot of air circulation. I have never germinated seed, but root cuttings take well and establish well in normal greenhouse conditions (in bright shade) with no supplemental humidity. But this is probably an entirely different scenario.

I will make a point of increasing air access. I am using a water-wicking system in hopes of providing sufficient moisture without saturating the soil. If trouble occurs I can dry out the soil fairly quickly, I think. I now have two sprouts! They still have the seed coats covering the cotyledons. If either of them show those tell-tale signs of brown staining I will dry out the medium and open things up even more. I'm watching them very closely. - Mark

Congrats, Mark! Sounds like the Regia seeds from the seed bank have excellent viability according to the reports from a few other growers! For what it's worth, I've made a little article that explains a bit more of how you can feed your seedlings, in case this is something you haven't tried before: www.growsundews.com/sundews/Germinating_and_Growing_Sundews_from_Seed.html#Speeding_up_the_Growth_of_Your_Seedlings Keep in mind that the video I link to on the page is for feeding plantlets, which are significantly larger than small seedlings- so use an even smaller amount of food for them.

Thanks, sundewman! This will be useful soon, hopefully.
While I now have more sprouts none of them have managed to kick off their seed coats. On the other hand their stems are green and clean-looking. No sign of damping off.
It is nice to hear that others are having success with germination as well.

I have grown quite a lot of Drosera regia from seed and never really found them a problem. I tend to grow my Drosera regia in a sphagnum/perlite mix, including for sowing seed using dried sphagnum so that it does not swamp the seedlings. Peat sand mixes work as well, evidence being that my plants seed over other pots and come up quite happily, but when I have deliberately sown into peat sand type mixes I do get lower survival rate for seedlings. I only really get dieback if I sow seeds in the autumn as soon as they are ripe, and a proportion of seedlings will die over winter in my cool greenhouse (5°C minimum), so for that reason I tend to sow seeds in the spring. One thing they really do not like is being transplanted when they are small, so wait until they are a good size before moving them into bigger pots, I would say when they are about 5 cm plus, which for me is about three years old.

It is great to get so much useful advice. Just the sort of things that could make the difference between success and failure. I appreciate it, gardenofeden, and everyone else who outlines their experiences with D. regia.
With so many seed packets from the seedbank out there I am expecting that there are a lot of us who can use some experienced advice.
- Mark

I planted eight Drosera regia seed from my packet on 28Jan2011. I soaked the seed overnight in water that was initially scalding (about 120F), and with a drop of dish soap. I let the water cool and the seeds soak, overnight and then I plucked each seed from the soapy water and placed them equidistant on the surface of a 2-1/4" square pot of moistened milled sphagnum moss. Today, 6Feb2011 I noticed that two of the eight seed have a radicle emerging from one end of their seed coats (the beginnings of germination). Now I can duplicate the process with the remainder of the seed (before the seed begins to lose viability).

I've germinated seed of Drosera regia about four different times through the years. I never managed to keep seedlings alive beyond about 1/2 inch tall. Like Joseph, I have had my fair share of struggles growing D. regia from seed to maturity but I'm trying again.... I sowed 24 seeds on Jan 14 and had 21 sprouts on Feb 2. Great germination imo. Thanks to whoever donated fresh, viable seeds to the seedbank! :hail: Now comes the part that has been historically difficult for me - keeping them alive ... :0o: Not much to see - but here they are (2.5" pot)(looks like I should have used a larger pot):
