Pop Quiz: Seedlings, Cuttings and Dragonfruit

I'm giving a pop quiz to use... I mean, test your knowledge of propagation.  Here's question number one!

Chamaedorea Seedlings

As some of you know, I have this odd habit of planting seedlings of different species together in the same container.  I have a few good reasons, one of which is derived of sheer laziness...

If they're all planted together I don't miss any waterings and I save water at the same time.  Since I have to water everything on my balcony the old fashioned way with a watering can, one less trip is a good thing.

I've also noticed that the ever present damping off disease and its attendant fungus gnats leave seedlings alone when there's other plants in the container.  Not a single one of the seedlings in this container or any other that I've tried this way have "damped off".

The other reason is so that when I eventually transplant the container to my parent's place, there's built in shade so that the transition from my full shade balcony to the very sunny garden is an easy one.

Boy is my hand pale.  Anyways, here's the container up close so that you can see the chamaedorea radicalis seedlings beneath the butterfly cassia and scarlet butterfly weed.  The ones with the big leaves germinated first, but the smaller ones in the lower left are yellow and a little anemic looking. I'm worried that the other plants are being nutrient hogs, but I'm still on the fence over dividing the palms or leaving them as a "multiple trunk"  So here's question  #1:

1.  Should I 

(a)  Go ahead and plant this in the garden now,
(b)  Cut back all but a few of the butterfly weed and butterfly cassia,
(c)  Forgo my method and just attempt division?
(d)  None of the above

Mystery Seedling

Okay, so there's another downside to my crazy an mixed up habits. In my carefully (I'm not fooling anyone) arranged container of wild coffee, cherimoya and coontie cycad, I have a mystery seedling popping up.  Of course it wouldn't be a mystery if I was more organized.

I could have planted it after an excursion to south Florida, possibly a "Pink Dwarf Poinciana" aka caesalpinia pulcherrima from a seed collected at a city park.
To make things more complicated, I've also planted jacaranda, yellow poinciana and poinciana seeds over the last couple of years as well, and when they don't sprout or the other seedlings damp off, I transfer them to another container with plants already growing.  Like I said, It does cut down on dampoff that way.

2.  What is the mystery seedling?

(a)  Pink Dwarf Poinciana
(b)  Jacaranda
(c)  Yellow Poinciana
(d)  Poinciana
(e)  None of the above.

Mystery Sedum

Another NOID question!  This sedum cutting comes to us from Chicago, via a coworker of mine. 

Its the silvery one in the middle.

When it grew in Chicago, it showed a typical upright growth habit and flowered.  Now that my coworker has taken it to Florida, it sprawls and flops over, taking root via its aerial roots!  He says that it grows completely differently.

This is a good one for anyone who lives or has lived up north, since nothing in my personal library of Florida and tropical gardening is of any use.

3.  This sedum is ___________.

Dragonfruit Seedling Division

Note the pineapple seedlings in the middle!

These dragonfruit plants were started from seed last fall, and I didn't know the first thing about dragonfruit cultivation back then.  All I wanted was to just germinate them and keep them alive, with the possibility of fruit not really crossing my mind.  

Since then I've found some great resources...

Here's some photos of commercial growing methods at http://www.vivapitaya.com/grow.htm like the one pictured to the left.

I discussed growing dragonfruit on the Florida Gardenweb Forum and they had some great ideas...

So now it seems like it would be a good idea to divide the seedlings and transplant to individual pots!  I have a cell pack tray I could transplant them to, and maybe even provide some sticks and twine to train them vertically!  Eventually I could pot them up, sink them into the ground for stability and take them indoors in winter!  Any ideas?

4.  Essay Question:  Share your ideas concerning the preceding selection on dragonfruit.

Extra Credit:  What do you think of my business card design?  This is only the back of the card.  I was inspired by Danger Garden's superb stationary design and decided to bite the bullet and get some printed.  I provided a link to her current post, so you can see her awesome garden all in one posting!
