Plant of the Month for June, 2012

 (AL-lee-um fist-yoo-LOW-sum)

General Information:

Allium fistulosum is a perennial onion that is good to eat and makes a great garden plant. It has many common names but the most common are welsh onion or Japanese bunching onion. "Welsh" is a corruption of the German "Walsch," meaning "foreign," and has no reference to Wales.

This plant makes very thick round stems that are hollow ("fistulosum" means "hollow") and a bluish-green color. The flowers develop very slowly, giving you a show for a good part of the summer. The buds are very unique looking for a perennial plant and stand out nicely in your garden. As they slowly open over several days the greenish white flowers emerge from their paper thin covering. Even the seed heads are attractive.
