If you're not growing this, start some NOW!! I doubt I'll ever be growing varieties of regular Italian flat-leaf parsley again after growing & sampling this baby.
The stalks are around 10"-12" long ending in large tri-leaflets that are about 1/2 a palm-size. Four of these stems not only yielded the same amount as a small fist-full of regular flat-leaf, but the flavor was so superior that the amount difference didn't even matter to me. In addition, the stalks are tender enough that, if minced, can easily be added to your dish along with the chopped leaves.
I bought some seeds for this early this year, but after badly breaking my wrist & other health problems, didn't get to sow them. Imagine my delight when my local farmers market had seedlings of them for sale!! I'm so glad I indulged myself, especially since so little of this plant goes such a long way.
And it's decorative as well! I currently have mine in a large glazed ceramic planter along with some "Blue Moon" lobelia & white Sweet Alyssum. Very pretty.
Seeds of this variety are available from a number of online companies - "Seeds of Italy", "Johnny's", "Pinetree". Just do a search for "Giant of Italy" parsley. Definitely worth a spot in the garden.
Can't wait to see how cold-hardy it is!
