From the first picture and this one, looks a bit like a member of the Zingiberacea family (ginger lilies). Mine die right off in autumn and I forget all about some but when comes spring those shoots, like in your first picture, appear up from the ground. but you'd have to be at least about zone 10 (sub-tropics) for that to happen, and have planted the rootstocks (rhizomes, whatever) previously.

Yep, organic p. I think you have a slightly moth eaten conker tree! Most likely horse chestnut rather than buckeye in the UK. Dig down a bit - you'll find a conker on the end.

2nd photo did not go through. I've been told from the flower photo in a different post that it's a Epipactic Helliborne.

Sorry for the delayed reply, but yes, Kalanchoes make flowers. K. blossfeldiana is referred to as florist Kalanchoe, known for its' prolific blooms. Not totally sure that's what it is, but if so, it would be likely to make flowers during the first half of the year, if it has enough light. If this is a landscape plant in Z9, it may be something else, not sure where Kal begins to be hardy, if at all. May be like Coleus, almost sure to die, roots and all, from one hard frost. IDK.
