Gave me the chills to see picture of this beautiful flower and realize
when it last bloomed...

This is a very interesting article. I would have liked to know a bit
more about the process used to grow the plant from tissue. Cloning
basics, I assume.
I am always amazed at the resiliency of some things I can get to grow.
I am notorious for placing almost any type of seed I see into a pot of
dirt, then standing back and watching. I have some wonderful patio
plants for my efforts, too.
A year ago I had brunch at the Cosmopolitan in Las Vegas and there
were dried dates on my fruit plate. I saved the seeds. I have a date
palm growing. 10 Days ago, I found a forgotten cache of 8 varieties
of tomato seeds dated 2003 and decided to throw caution to the wind
and direct sow them in a bed, putting more seed per hole than I
usually would. Damn near all of them are coming up. I will have to do
some serious thinning.
These instances are not stretching botanical behavior too much, but it
is always fun getting things to sprout. I love to nurture volunteers
that show up in the garden, too.
Now I must seek out something over 30,000 years old to play with.
The composition of the medium, particularly the plant hormones and the
nitrogen source (nitrate versus ammonium salts or amino acids) have
profound effects on the morphology of the tissues that grow from the
initial explant. For example, an excess of auxin will often result in a
proliferation of roots, while an excess of cytokinin may yield shoots. A
balance of both auxin and cytokinin will often produce an unorganised
growth of cells, or callus, but the morphology of the outgrowth will
depend on the plant species as well as the medium composition. As
cultures grow, pieces are typically sliced off and transferred to new
media (subcultured) to allow for growth or to alter the morphology of
the culture. The skill and experience of the tissue culturist are
important in judging which pieces to culture and which to discard.
it would really be interesting to compare its
genetics against one that has been blooming all
along (to compare the rate of mutations, because
that is a measurement commonly used in other
