This time I'm calling it "MY, how you've grown" because these really have excelled themselves. Sadly, to a degree where we had to dig out and replace them, as they were in a narrow brick-built bed in a client's premises in Andover, and they were wedged in solid (and took quite a lot of digging out!). So they've been a victim of their own success, sadly.
So these were four Nolina or Beaucarnea Recurvata (which ever name is currently in fashion, I can't keep up) with their woody bulbs about 40cm wide. What's incredible here is that I planted these in 2002, when their rootballs fitted in 13cm pots, exactly like the empty pot I've placed in the photo. They looked like the ones on the left.
But they've grown just a bit since then.
Want to know about Nolinas/Beaucarneas? They need lots of light, very little water, and will tolerate low temperature, so they are a perfect porch/conservatory plant. A word of advice though: they have a rough leaf edge and can give you a nasty 'paper cut' if you run your fingers down the leaves.
