Tuberous Drosera

[Jcal]

Sweet. Are they waking up already?

I'll skip the risk of separating the utric tubers. Not sure if just would be wise.

 

[Cthulhu138]

Some are already waking up, I actually had to plant a few of them immediately since they arrived bearing 1" stolons. D.graniticola was the furthest along.

I didn't have much luck with separating U.menziesii tubers from the main bunch. I'm not sure if it was the actual separating that bothered them or the fact that I let them get too dry during dormancy. I'll have to play with that again in the future.

There seems to be some confusion about the recent revisions to the various complexes of tuberous Drosera. In the last few years, many of the plants formerly described as subspecies have been given their own species status and in addition, several new species have been described. All of these revisions are explained in their entirety in Carnivorous Plants of Australia, Magnum Opus by Allen Lowrie, 2013 (An updated work from his previous 3 volumes, Carnivorous Plants of Australia Vols. 1,2 & 3 1987-1998). The information contained within has been invaluable to me in my efforts to grow these plants.

Work is still ongoing with these plants and there are sure to be more new species and more changes in the near future. I will try to keep this information updated to the best of my abilities.

Drosera hookeri


Drosera humilis


Drosera menziesii




Drosera modesta


Drosera peltata




Drosera purpurascens - The flowers of this species are intensely sweet smelling. They fill the whole room with a strong Honeysuckle (Lonicera sp.) like aroma.










Drosera rupicola


Drosera subhirtella


One of the Tuberous Drosera trays.

 

[kulamauiman]

I wish mine would grow straight and tall. Mine seem to want to lean all the time.....

 

[Cthulhu138]

Try putting a 24" wooden dowel into the middle of the pot. The climbing or scrambling species should find it and use it for support. I'm sure the wind has something to do with your plants wanting to lean, growing them outside as you do.

got capensis for that have more problems with the non-climbing or non scrambling ones. like D. menziesii or D. auriculata

 

[Cthulhu138]

Ah, that sucks !

 

[bluemax]

I was given a D. hookeri (assumed) and I have had to use a bamboo skewer to support it as it wants to fall over, especially as it has 4 growth tips now. I blame the leaning on not enough light, though the plant gets enough to have a lot of red in its coloration.

 

[Cthulhu138]

D.hookeri is rigid enough to stand on it's own, unless like Mach you have wind issues (pun intended Ha!). That species is also a solid green/yellow even under intense light.

Mach recently noticed that some plants that he'd gotten labeled as D.peltata "Tasmanian Red" (or something to that effect) were red and did not look quite right for the species. His plants are likely D.gracilis (formerly D.peltata ssp.gracilis). Many of these plants were collected, grown and distributed long before they were properly studied and understood. This has led to a lot of mixed up data on them. I have a pot of plants I received a few years back as "D.peltata "Pink Flower" and D.peltata "White Flower". As it turns out, the "White Flower" plants are actually D.hookeri and the "Pink Flower" are D.peltata.

Do you have any photos ?

Drosera purpurascens

 

[tje25]

Beautiful as usual Johnny! I really like that D. porrecta!

 

[Cthulhu138]

D.porrecta is indeed a great species. I love it's aerial basal rosettes. Very unique.

 

[bluemax]

I think the D. purpurascens is my fave of the group. Something about the combination of the color and the symmetry...

 

[SFLguy]

Is the Zonaria already dormant? How does it look like all dried out?

 

[Cthulhu138]

The D.zonaria is getting ready to go dormant for the season. The 1st signs are the tentacles drying up and the edges of the leaves starting to brown. It will probably be fully dormant by the end of April.

This is how it looks while dormant:

Drosera erythrorhiza - New Plant Just Waking Up.


Drosera humilis


Drosera purpurascens


Drosera lowriei - "Giant"






And now for something completely different........

No idea what this D.squamosa decided to do this year.....

 

[bluemax]

Those are some spectacular masses of flowers on the Drosera lowriei - "Giant"!

 

[Cthulhu138]

Those are some spectacular masses of flowers on the Drosera lowriei - "Giant"!

Indeed ! I didn't even catch them at their height of flowering. These plants are easily twice the size of my D.lowriei "Type" plants. I pollinated as many flowers as I could so, fingers crossed for seeds !
