Superball

Sunball

I don't know about the other two, but Fireball is larger than Superball, and more sprawling. Superball is Fireball x compacta, so the offshoots are smaller and more compact. It doesn't seem to get a dark red as fireball. Superball & Super Fireball are sometimes used as interchangeable names for the same plant. Sunball is probably the most compact of them all. You can find good descriptions of each on Tropiflora.

Thanks for the info, DG.

I know that these names are incorrectly used interchangeably - and hence the confusion! But these are all unique, separately-registered plants - for sure - as can be confirmed on the Bromeliad Society International (BSI) registry.

I looked them up on Tropiflora but only found sunball, which you had linked, and superball. They do not have a listing for fireball (only fireball green form) or super fireball.

I wish that someone who has all four plants would take a photo of them all together! A picture is worth a thousand words.... someone on the Bromeliad Forum (cross-posted there) may be able to help us with that. I'm interested in mature size and color and a few good photos would show that. :)

Size depends on the conditions they are grown under. My friend had a fireball that looked a lot like the sunball in his yard, but once I got it and potted it up, it grew more like the original fireball. This is a picture of mine. Since we have freezes, I have to bring it inside in the winter, so it fades to green. It's not quite colored up all the way yet, due to so much cloudy weather, but it will get dark red when the sun stays out awhile. I measured the largest rosette (on the right) and it's 11 inches across. It's still in its original 6" pot. I only have one place where I get enough sun for it to color up completely. It really needs full sun to color properly, as do most neos.

The pot my Fireball is in is a 6-inch clay pot. It's been in it all along, since it was a baby. I just keep the cups full of water and keep it watered well, and it grows and grows. Took FOREVER to really get started though. It's about 5 years old, grown from a single pup.

I'm not sure about those varieties coloring up dark red. I know the Fireball and Sunball will.

I had a NOID neo which was a medium red/burgundy. It didn't pup as readily as some of them, but it was still gorgeous. I also have a striped mini neo that doesn't color up until right before it blooms. Can't remember the name, and it hardly pups at all. It pupped out a bunch of green runners once, which I took off and put into another pot, and it grew up a palm tree. The variegated one has been in a 4-inch pot for two years and never pupped.

Broms are weird. I do miss my huge landscape broms, especially my Aechmeas, and of those especially blanchetiana, but I had to leave those behind in a warmer place.

Did you have some nice Aechmeas? How did they do over the winter? My A. Malva look terrible. They are both going to pup, so they have a place in Sick Bay, but once I can remove the pups, the mother plants must go.

Double potted, so it won't fall over. And yes, I hate that outter pot... U.G.L.Y. That's what ugly plants get... ugly pots.

I've considered getting a blanchetiana, just because they are so outstanding, but I don't think it would survive my winter. My neos do sooooo much better. Never lost a neo, even after 22-23 degree lows.

Got two new red broms yesterday via a swap. I was hoping they were 'Super Fireball' but I suspect they are 'Fireball'. Nevertheless, they are beautiful and I am happy with the swap.
