tuberous Drosera

I'd like too... I just got some seeds and I hope I will succeed. My  favorite is erythrorhiza. Have you seen all the pics on www.cephalotus.net

I'm trying to germinate some seeds of whittakerii ssp whittakeri. I'm growing two D.peltatas.
 
Hey Martin,
I don't grow any tubies but could I use that nice pic as wallpaper? :cheesy:
 
Only one I have is whittakeri ssp. whittakeri

Supposed to have an orange flower... they are growing now so we will see soon.

I would like to try a tuberous also...hopefully this spring I can try at least one if I can find some to buy.

Hi

I would suggest to start with an easy spezies...
Drosera auriculata, peltata or menziesii.
The seed of this spezies germinates really easy.
I never succeeded with seed of other tuberous Drosera... This year I'll give them a "heat-treament" during summer.

Hmmm, spring is not the best time to start with a tuberous Drosera because you will only have a pot of dry peat and sand for the next 6 months... ;o)

Tuberous Drosera are the ideal plants for people who enjoy long summer vecancies, because you can put them into an cool room and leave them untouched for several months.

If you want to start with seed, the you should hurry !
 
I'm growing a D. peltata.

Here's a picture...

Tuberous Drosera are wintergrowing species, and need cool conditons for both germination of seed and growth in general. The main problem is to be able to give them enough sunlight in the winter - they are light loving plants, not suited for terrarium or indoor culture under flourescents. Seed can lie dormant for up to 3 years, as these plants are part of the Australian "Brushfire" ecology: many require stratification by heat and smoke in order to germinate (bulbosa, erythrorhiza) In temp. above 60F seed will not germinate, no matter what stratification has been done. The use of GA3 has not proved effective for me, I have heard that smoke water is effective in some cases. Plants from seed take up to 5 years to mature, and must have successful dormancy during the summer months. The plants produce tubers during active growth (with good light!) that allow for the next seasons growth. Tubers acquired from Australia need to be acclimated to growth in our hemisphere, and will not be successful if planted immediately upon harvest from there. Plants go dormant as the warm season progresses, and it is vital that the potted plants be allowed to dry off s-l-o-w-l-y so that the energy reserves in the plant can be stored in the developing tuber: if they dry too quickly this will not happen. Peltata and auriculata are the least sensitive to this, and are good starter species. Tray watering is not acceptable, and can lead to tubers rotting, esp. during the dormancy. Seed as well should not be left sitting in water, and high humidity is not a requirement for germination. Here is a good synopsis from a friend in the UK:

uhh...I think now I'll wait a while before I try peltata
sounds like what I'd need is a cooled greenhouse

Don't give up! Peltata is the most forgiving of the tuberous species, and isn't that difficult. You just have to give the plants what they need. This one may grow under flourescents, but not in warm conditions constantly. If you can provide a night time drop of @ 5-10 degrees, it should do Ok. I grew mine from seed. The more light the better. Start the seeds when the summer heat is done. This is a really beautiful plant
that more people should grow and experience, and the seed germinates far easier than many other tuberous species. Remember to dry the pots off slowly for good tuber formation when the plant shows signs of dormancy. This is often the hardest part of their culture.

I grow D. Peltata, D. Whittakeri and D. Erythrorhiza.
D. Erythrorhiza grows well but never produces any dew on its leaves. The other two grow laike crazy! My peltata pot is full of about 4 mature stems and hundreds of seedlings in various stages of growth. D. Peltata and Whittakeri are also the only tuberous sundews that dont require drying out during dormancy. I leave my pots standing in the water trays but hidden away by larger pots.

That's the spirit! Remind me next fall, and I will send you some seed to try.
