Seachem is the company that makes Flourish.  The labels states, 
"Flourish is a growth stimulator for aquarium plants."  "It caintains a 
broad spectrum of essential trace elements, vitamins, and amino acids." 
"It is rich in iron, magnesium, calcium, potassium, inositol, choline, 
B12, biotin, and other factors determined to be beneficial to aquatic 
plants."  "It contains no phosphates or nitrates that would promote 
algae proliferation."  "Flourish is concentrated: each 250ml treates 
over 12,000 gallons."

Seachem recently also came out with another product called Flourish 
Tabs that are slow dissolving tablets designed to be inserted in the 
gravel in proximity to aquatic plants roots.  The tablets last for 
approximately 3 months.  It supposedly has similar ingredients as 
Flourish but can be used in conjunction with the other product.

I use both products and have been satisfied with the results.  However, 
I also use other products to ensure that I am covering all bases in 
terms of supplements.
