Plant identification - Japanese Hops #872389

Asked June 10, 2024, 11:23 AM EDT

I’m hoping you can help identify a plant that showed up in the vegetable garden that I haven’t seen before. I haven’t seen it flower and just pulled it this weekend so I can plant. This area had corn and sweet potatoes last summer. The plant grows like crazy, has fuzzy stems, and roots run fairly deep. Can you please help identify it? Thanks!

Hi, 

This looks like Japanese Hops. You can compare the photos on the link with what you have and if so, it's invasive and should be removed.

Hi Emily,

How on earth do these things appear out of nowhere?  I am just scratching my head.

From a non-botanist would this be 7 lobes or am I counting wrong?

Thank you so much,

Janice

It looks like the younger leaves do have the 7 lobes but the older ones are 5, it isn't the sole thing to use as a characterization. 

The seeds can travel on fur or animals so they move easily unfortunatley.
