Result of lab experiments, they terrorize a garden near you. :P
They are supposedly african marigolds. Leaf color varies too

They look like a cross with Mexican marigolds?
What were irradiated---the seeds or the plants?

The seeds were, if the plants had been most would die or burn. This is how new cultivars can be created if normal hybridization yields slow results, but the study also shows effects of radiation on plants in areas after nuclear war.
It said african marigolds, these are quite tall at least 3 feet, I don't think Mexican marigolds get that big.

And we need to know what radiation they were using?
Some people have tried microwaving seeds to get better germination?

Here's where I got them it should answer your questions. http://www.carolina.com/plant-...

Very high energy gamma radiation.
The same used in cancer therapy.

More giants!

This odd one just bloomed, looks almost like a wild marigold reverted back.

I measured this giant today. (same plant in different lighting)

Here is an oddity, a dwarf plant! Flower is the size of a quarter coin only and less than a foot tall! Guess it didnt get the giant gene? And here is a bright orange flower, yes its really this bright!

Interesting outcome. Looks like a wide variation. That last one really pops!

These are a few of mine, which look so much like yours! And the flowers last a LONG time.

They look great! And your right the flowers last so long its like the perfect marigold!

Thanx! I wish I could keep them through the winter...I'm going to give it a shot, anyway...I've grown very attached to my new companions!

Sending people here seeds ensures they never truly die out

Heh heh heh...

Now that I gave seeds this year more people will grow these Giants

I can't wait to see how these turn out for me!! (well, truthfully, I just can't wait to plant something, ANYTHING, at this point... )
