Drosera x [collinsiae x tokaiensis]

[Devon]

Hello everyone,

I'd like to introduce my new-ish hybrid. It is Drosera collinsiae x tokaiensis as the title says. It has started to flower for me this month, so soon I will know if it's sterile or fertile. My bets are on sterile.

Here are what the parent plants look like:



I couldn't find my own D. tokaiensis photo, so I borrowed this wonderful one from growsundews.com



And the hybrid:



This is the healthiest plant right now. It started to flower, but I broke it accidentally when transplanting it which is why it's bigger than the others at the moment.





Another leaf for comparison. The shape and colour varies a little bit with each plant.



I don't have a shot of the flower in bloom yet. I'm waiting until I catch it fully open so I can get a good look at it.

The flower is mostly pink with a hint of purple from the D. collinsiae side.



I find it interesting how similar it looks to D. collinsiae "Faryland". Perhaps the Faryland form is a hybrid too.

I'm not sure if I want to try registering this plant as a cultivar or not. Sure it's a hybrid, but its not very unique in shape compared to a plant like D. capillaris or something.

I will update this thread as the plants grow.

Thanks for looking!

Very nice. Are you sure these are hybrids? Did you use the "Ivan Snyder Protocol" and remove the anthers and washing off the stamens prior to cross-pollinating? This reduces the chances of self-pollination.

Typically with the F1 generation of hybrids you will see a great deal of variation in the offspring. If the offspring are fertile or made fertile the F2 generation will have a lot more uniformity.

For example with Ivan Snyder's tetraploid D. beleziana some of the F1 generation plants look very much like D. rotundifolia while others look like a "typical" D. beleziana. I don't have any that look like D.intermedia.

D. tokaiensis (fertile) is a hexaploid (2n=60) while D. collinsiae is a tetraploid (2n=40). If I get this right hybridization should result in an pentaploid (2n=50) which most likely be sterile. Inducing alloploidy with say Colchine would result in a hecatoploid (2n=100) and will probably be unstable.

Keep us informed.

I did indeed use the Ivan Snyder protocol. So far it's the only way I've been able to successfully make hybrids, not including D. binata.

If I end up getting that colchicine soon, I will definitely try treating cuttings with it anyway just to see what happens. When the time comes I will post the results to this thread.

Here is a photo of the flower in bloom.

Update:



This is the top left plant. I like the clumping/compact look this plant has.


This one has really taken off, and it looks like the newer leaves are going to have more colour now that I moved it closer to the lights.






The other two are just starting to make bigger leaves, so hopefully they'll catch up in size soon and maybe gain some colour!

This hybrid certainly has a nice shape to it, and great flowers!

What is the speed of movement when catching prey?

Same as most other 'dews - a couple hours to fully curl around it's "prey" (fishfood) or more depending on how much movement there is.

I was wondering because I am a fan of fast plants. Thus why I am growing drosera burmannii, even though I am not a fan of annuals.

Hmm. . . There isn't a huge selection of fast moving Drosera to choose from. Only D. sessifolia, D. burmannii, and D. glanduligera.

It is pretty neat to see them move though. The first time I had D. burmannii I would poke the tentacles with a toothpick every now and then just to see it move.

[sykosarah]

We are all guilty of doing that or some equivalent to our moving carnivorous plants. I have demonstrated the awesomeness of my Venus flytrap to my friends before by sliding a thread through it ( if I used anything bigger, it closed so fast I wouldn't be able to safely pull it out).

[hcarlton]

D. burmannii and sessilifolia don't have to be annuals. Rigorous feeding, and I have had both species last a couple years already and are still going....

[sykosarah]

But I doubt they will be as long lived as other drosera.

[hcarlton]

I know of at least one person on here who has kept the same forms as I have for over 5 years....

[sykosarah]

but a lot of carnivorous plants live for decades

[hcarlton]

You'd be hard pressed to find a lot of sundew species that live past 10 though.... although with hybrid vigor, plants like Devon's might well be in that category.
