Ooo can't help but i like the bottom one very unusual!

These are my neighbours plants she has not a clue what they are nore have I

The last one looks like a spikey lettice But I am sure its not

The first one is a petasites, probably P. japonicus. They grow in full or part shade in soil that is permanently moist. Grows from rhizomes and may become invasive

The second one is silybum marianum, a biennial in the thistle family. It grows in full sun in well-drained soil that is poor to moderately fertile

The first is a Butterbur, an invasive wild plant that grows in moist shade.

And something I would weed out rapidly!

I agree ...., first pic is Petasites japonicus, I have P hybridus too. OK if there is plenty of space for them, mine are along the banks of my brook so fine and so nice to see their flowers at this time of year. After the flowers come the big leaves which turn bronze later in the year. Is invasive but if you have the room, they are OK.

2nd pic definitely Silybum, the leaves are so gorgeous :-)
