Great new forum! I will be visiting the subject often.
Now, the topic--I know we'd love to say all plants are incredibly beautiful jewels, but many of us grow a plant that is just plain ugly. I have nothing against ugly plants--they are just a fun-for-me topic to discuss.
Obviously, dead plants are the least beautiful. What I mean is healthy and well-grown plants that look their best, which is bad.
My ugliest plant is called Pilea 'Purple Waffle'. It has a permanently crinkled, "waffled", dead appearance. I checked and am pretty certain it is alive, but you never know...
Calling all plant growers: what are your ugliest plants?
