@devon: thanks very much. petiolaris complex is probably my favorite CPs. compact, attractive, not to mention that they are just as difficult to reproduce like nepenthes. :lol:
 
  • #202
Nice petiolaris. How are you growing them?
 
  • #203
very hot conditions- temps around 90-110F. i do not allow the temps to drop below 70F. they may be kept waterlogged if not dormant. bright light as well.

NaN, WOW! how did you manage to grow Falconeri like that ? looks like it's pumped up with fertilizer or something, crazy growth...really well done.

Amphirion loving your collages and great collection.

Here are my D. capillaris from yesterday. Love the way these seedlings are turning out :)

nicely captured drew. everything looks immaculate!

Gotta love those sparkly rosetted plants.

Amph,
Great summary collage of the petiolaris - easily the best group of dews out there for many reasons (imho).

Gotta love those sparkly rosetted plants.
My curmudgeonly side has difficulty continuing to appreciate those dews once I realized they resided in a bed of U. bisquamata. :0o:

Thanks guys!

lol I like them because they keep algae growth down and look better than bare peat/sand

True - but there are many others which could perform the same function without being uncontrollably invasive. The day will come when you want to grow something without bisquamata in the pot .... Curmudgeon/prophet out. :lol:

Before and after, about six months:

I didn't bother correcting the white balance on any of these pics obviously.

Some updates: So far no seed from the supposed D. capensis × aliciae hybrid - perhaps it is indeed a hybrid. Although it could just be an infertile D. capensis broadleaf clone that some unscrupulous people are making money off of marketing it as something different. Isn't there another D. capensis clone that is infertile that may or may not be a hybrid. Was it Bain's Rocket?

The supposed D. ultramafica clone I have is putting up a flower stalk. Maybe flower details will reveal its identity. It has been suggested that I cross it with D. spatulata to see if it produces fertile offspring or not. Apparently Robert Gibson did this with D. neocaledonica to see if it was D. spatulata or not. I think I have some D. spatulata in flower now too.

D. rorimae generic form from BCP:

For the hybrid debate, here is one of my capensis "alba" x aliciae plants.

Not very likely, but received as D. capillaris "Costa Rica" -Looks like a spatulata, but what do I know ???

D. rorimae plantlets, for days!

I'm still having issues with my collection. Lots of taxonomic discrepancies.

Just some dews doing time.

I put this messy assemblage together mostly out of leaf cuttings from this spring.

This is the crown of a mid-sized D. multifida 'extrema' with a misc. mess of new "test tube babies" just inches away.

Drosera spatulata competing for space with P. primuliflora

These are my babies... the good, the bad, and the not as pretty. :water:

Very nice indeed.

Re: D. ultramafica vs D. spatulata

Ok, I've been reading the paper on D. ultramafica.

http://www.ingentaconnect.com/content/nhn/blumea/2011/00000056/00000001/art00004

There is a table of the differences between D. ultramfica and D. spatulata. Notable:
  • D. ultramafica is stem forming. Old D. spatulata may form a skirt of dead leaves but (at least with D. spatulata in the same area) do not have upright growing leaves - they are all apressed towards the ground.
  • The flower scapes on D. spatulata are covered with glandular trichomes. D. ultramafica is not.
  • D. spatulata does not grow in ultramafic soils.
  • D. ultramafica seed is reticulate vs granulate for D. spatulata.


If there has been D. spatulata mixed in with D. ultramafica in cultivation it must have come from some other source than from around where D. ultramafica grows since the plants in those areas do not grow upright leaves.

It shouldn't be difficult to ID from seed.

@Nan: I think that most people have the D. spatulata mislabeled as D. ultramafica, including what BCP sells. Mine are currently flowering, so I'll be able to collect seed from them soon to identify them. . . Although I am 90% sure they are not D. ultramafica.

Regarding the D. capensis "albino" x aliciae, I have been growing this plant for 2 years now. I think that there is some aliciae in it. The flower resembles D. aliciae a little bit, and of course the wide leaves, but then why is it fertile? Was is treated with colchicine at one point or something? As you might have noticed, I don't really understand how the whole hybrid thing works yet.

Here are two pictures from last year (excuse the silly "signature" on the flower pic):

Devon, I'd love some tips on how to grow the "ultramafica" from BCP. It has been a royal diva for me so far... It looks like an ugly green monster at the moment. With no dew. I hail your superior growing skills :hail:

Aw shuwcks. :blush:

I actually just grow it like most of my other 'dews on the shelft under my t8 lights in low humdity.

The D. oblanceolata I received from CPgeek took a very, very long time to start growing healthy leaves. It grew super slowly compared to the seed grown ones I had, which have been in my conditions since germination, and continued to grow to maturity while the mature one from Rob stayed small. So what I'm getting at is that yours are probably still under stress from the climate change, and are taking their time to start growing god looking leaves again. That's my guess, anyway.

Perhaps try taking cuttings and starting fresh, that sometimes works for me. . . Or you can wait until it pulls through.

Cheers!
