Okay

Gonna try again.

 

Dypsis baronii don't germ well for me, no doubt because of my inteptitude.

I had 11/11 (100%) germination from a RPS batch last year. No added heat, just indoor room temperature in baggies of sphagnum moss. Here’s one in April about 4-5 months after germination. A few have now opened the second frond 7-8 months after germination. A solid grower for me in cool Melbourne, I’m keeping them in nearly full shade for now.

Hilliard, what is your soil mix? 

In a freeable mix the roots will develop alot quicker resulting in faster development. 

I've got these in equal parts 

Coco coir for pots, composted pine bark fines, course perlite, and hydrocorn (expanded clay pebbles). 

I just used a commercial potting mix that's inoculated with a large number of beneficial microbes. My approach is like 'tough love' with some of these seedlings, so that only the most hardy survive infancy and would have a chance to grow more mature under my local conditions.  ;)

While I didn't get the same germination percentage you did (congrats!), I more or less used your propagation method on my seeds... except I did keep them on a heating mat until I was ready to pot them.

Dypsis baronii don’t need bottom heat. I germinate mine in winter in a tin garden shed in clear plastic storage bins that might get into the 20C range during the day and single digit at night. I get around 70% germination this way. From 10 black petiole seed I have 7 plants. 

Have germinated lots of standard D baronii this way.

You'll get colour on the others, in time

Nice color!  Definitely farther along than the two I have that germinated from RPS seed, which are still at the two-leaf stage. :unsure:

Is there any differences between Dypsis baronii 'Black Petiole' in PRS and Dypsis baronii 'Black stem' in palmpedia?

I finished up with 5 seedlings out of nine seeds sprouted. I can't remember what happened to the four that didn't make it, but I think they were undersized and browned-off shortly after germinating. I was probably a little ruthless too, and threw out a couple of runts! I'm not sure if I'm keeping these too wet, as you can see - leaf die-back appears premature on one of them. This has claimed a whole leaf on one of the five. Do they prefer only lightly moist?

I saved my shipped seedlings without a developed leaf yet in a mix of leca, lava, pine bark and a small portion of coir.

Apart from perlite and lava in its place, I used same ingredients to save few seedlings of this kind, which endured a 3 weeks long journey but finally the seeds had been  separated.
