Last Friday, our group visited the Botanical Gardens, Orto
Botanico, in Florence. What I found most interesting was a single poppy plant, Papaver somniferum, or opium poppy.
It was planted among other “tossicita” or toxic plants like Nicotiana tabacum (tobacco) and Nerium oleander (Oleander). The
plant was completely dried up and without its beautiful red flowers that we see
all over Italy. (Although poppies come in all different colors!) All that
remained on the plant were the dried up, grayish-brown seedpods with their
signature flat tops.
Professor Starman pinched one of the seed heads off of its
stem and cracked it open onto her hand. Hundreds of tiny black seeds spilled
out. These are the seeds that would then be dried – to prevent germination –
and used for eating and baking. The seeds only contain small amounts of opiates
and are safe to eat in moderate portions.
Opiates are also cultivated from Papaver somniferum. Professor Starman explained how the fresh seed
head of a poppy would be cut on the outside and a latex substance, opium, would
ooze out. The same material from the plant that is used to make opium is used
to make morphine and codeine, too. Alkaloids in the plant provide pain relief.
However, like opium, the medicines also have addictive properties.
It is illegal to grow Papaver
somniferum in the U.S. unless you have a special license from the DEA or
work for a company growing them for food or medicinal uses. The legality of
opium poppies varies widely across the nation. In Italy, small numbers of the plant
can be grown as ornamentals but not for alkaloid collection.
I’ve been admiring the red poppies that line the Tuscany
region since we arrived to Castiglion Fiorentino. Learning more about the less
common and less seen opium poppy was very interesting!
