Maybe that's what they should call it, very vigorous.  This is the Latarulla cutting "ejp3" sells on eBay. 

I will cal it "Root-a-lot-a" unless it was Lattarulla.

Beats a "root-i-beg-ya"  ;)

Sir-Roots-Allot hehehe  I got big roots and I can not lie lol. Its the remix

Remix sells houses. PRO-MIX helps grow cuttings.

Three days later, quadruple the roots.  I am posting pics of both the Sphagnum/Perlite mix and the Fafard3B/Perlite mix - the one in the sphagnum mix is twice as thick, with a total of three terminal buds!!  I would think it would have more juice, I guess I am wrong.

3B mix is doing better on the skinnier cutting.  The Sphagnum mix has the more roots, but shorter roots.  The entire bottom of the cup looks like what you see pictured, lots of short roots; and it's like this around the total perimeter.

This thing is developing twice as fast as Conadria, which is my 2nd fastest rooter.  I think Sal's Gene is behind that, and Gino's Black is fourth in line for hardiest rooter.  Then MVSB, then Hardy Chicago, Negronne and some others are not worth naming.

Congrats Jason. You are a fast learner. Looks like you
need acreage soon.  I got some ejp3 cuttings and I hope
to have good results like yours. I am going to root them
in SM-Perlite mix. I am curious to see how ejp3 Latarrula
perform against the amber variant as well as introducing
the red variant to figgers here. The amber variant does
well in my zone. Another variant that works in my zone is
a big welcome. Thanks for posting those inspirational
pic's.

Thanks, Paul!

Last update before these little ones get moved to pots.  They have even surpassed my Conadria cuttings.  Gino's Black has outpaced my Sal's (gene).  But these "lotta-root-la" cuttings... ejp3 has something special here, definitely the easiest cutting I've ever rooted, I can't wait to taste the fruit, maybe will get lucky and have that experience at the end of this year?

I attached final pictures - the Turface/SM cutting finally caught up to and surpassed the 3B/Perlite cutting, but again - the 3B cutting is literally thinner than a pencil, while the Turface cutting is thicker than an woman's thumb. 

I notice that some of the 3B cutting's roots are browning, but I'm only registering a 2 on my meter.

Finally, a picture of my box with the better-rooting batch of cuttings - the entire middle row showing really good top growth is all Conadria.  the one farthest left has only 1-2 roots, the one with no growth has a gaggle of roots, and the last two with big leaves have good, moderate growth.  The back four are MVSB (2-node), MVSB (1-node), Sal (Gene), MVSB (3-node).  All showing reasonable rooting.  Front row is Gino's Black (3 roots showing) and the two lattarula pictured repeatedly in this thread for size/thickness comparison.

I chose not to move to pots.  Instead, I 'sleeved' the clear cups with an opaque cup and set them in the window.

Interestingly, the Spahnum/Turface cuttings are starting to blast off!  The Fafard3B/Perlite cuttings have been slow and steady....Sphagnum/Turface took a while to take off, but when they do, WHAMMO, lightning speed.

Figured I'd toss in a pic from my Blackberry (same as the others) for the heck of it.  Most of the orange mixed cups with lots of top growth are Conadria.  The two tip cuts in between the three Conadria are Lattarula.  The others are a Negronne air layer, a Bethlehem Black, and some nknowns.

Looking good Jason. Thanks for posting these pictures. I am going to borrow your red cup cover idea (instead of foil) for cuttings that need sunlight.

If you look at the bottom of these cups, there is almost a little 3mm "platform" the top half of the cup is mounted to.  It has the perfect little seam there to cut the cup. 

What I found is, by cutting the cup around that spot and taking the bottom entirely off, the rooting cup will sit about 1/4" off the floor of whatever you place them in.  In my mind, this gives more room for airflow, and doesn't impenge (sp?) on any roots that choose to grow out through the drain holes (I'm sure you've seen plenty of this too).

It's working out pretty well.

Updating on another thread.  Even with all of those wicked roots on both, the terminal bud never managed to break.  Over the last three weeks, I lost both of these cuttings.  I still have no idea why - they showed no signs of rot or root death.

Just goes to show, you can't win them all?

my vote for the easiest to root would be hollier.  you can't kill the damn things.  i think i took 8 cuttings, and now i have 8 little holliers. :).

I still haven't gotten a chance to cut into mine!  It is definitely growing like a champ.

Out of all the cuttings I started over the last 6 months, I have to say, the easiest to root and most prolific (combined) for me was Gino's Black. 

The best, most "explosive" rooter is the "Unkown Voiture #217" that I handed out cuttings of to several people this year, it took forever to pop rootlets in the bag, but when it did, they were rootbound in the cups in less than 3-4 weeks.

I don't know why, but I had a hard time with Hardy Chicago and Latarrula.  The HC was generally a poor rooter for me, and I'm on my last one, which I thought I was losing the other day.  The Latarrula rooted really freaking well, it was rooting by the time it got here, was very strong at rooting in the cup, but never broke terminal bud or sent sprouts.  After months in cups, the terminal bud finally started to shrivel, even with proper moisture and environment.

The most consistent cutting was Conadria - all varieties I have gotten (3 different - 2 kinds from UCD, one from a solid source in NY).  All cuttings rooted; all survived, even through hardships.

I can't even imagine what it's like for someone like Jon who roots hundreds of cuttings each year.

I wish you lived near me.  I'd give you a 40lb bag for free. 

My easiest to root is Doce. Followed by Lattarula Red & Hollier.
