a huge mullein

berarde

I shook some mullein seed from a garden rather special to me some five years ago. I had some flower 2 years ago, but  I believe they are biennial, and none last year. 2 years ago they grew about 5 feet tall from a rosette about 9 inches across. This year I have one flowering about 2.5 feet tall and a number of plants 9 inches across, but then a whopper like this one and another whopper on the way. If they are mullein how have they become huge? This one is about 3 1/2 feet across. It doesn't seem to be invasive and the plants I got two years ago were easy to move, but does this plant become invasive with its seeds?

Depends which ones they are, I have some giants here and they’re very tall.  I’m going to leave them to seed so I get a forest of them.

Depends on which genes the seed got from mum and dad.

I remember years ago a friend in Belgium whose garden was all azaleas and rhodos and ablaze with colour in late spring then very dull.   A verbascum/mullein seedling grew, and grew, and grew.  In late August she took a photo of her 6'4 husband standing on the top of a stepladder and almost touching the top of the flower spike.
