Unidentified Tall large leaf 'Beanstalk' in Hostas
by tina payne
Every summer a tall (as tall as our garage), large leafed 'beanstalk' grows mysteriously in my hosta bed. This year there are two of them! My husband pulls them up by the root and still it comes back!!!
Stop pulling them up - you're encouraging them!
I don't know what this could be - my first thought was maybe Hollyhock (Althea rosea), which get really tall, but they are biennial (taking two years to flower), and you would be able to identify it from the flowers which are spectacular and trumpet shaped all up the stem.
The leaves don't really give much away, except for the size, could they be some kind of tree?
It also resembles Castor Beans (Ricinus), but those are an annual, and wouldn't come back every year.
You don't say what happens if you leave it; does it die back to the ground? Branch out? Flower? Maybe that would tell you what it is, if it's some kind of perennial.
That will be your mission, should you choose to accept it; let it reach it's full height, and pay close attention to any flowers, and if it dies back or keeps growing the following year.
Sorry I can't help with it but I'm really curious as to what it will turn out to be!
Edited to add; I found this picture of hollyhock on Dave's Garden Website; it might not be exactly the same kind, but the leaves look close, for sure; Hollyhock.
