I know very little about bamboo, but when I saw this in a Key West garden earlier this year, the colours, textures and leaf patterns made me feel like an overexcited animal that has found something tasty in the street, sniffing and wagging its tail in delight.
I couldn’t decide which picture I liked best, so I’m sharing both for Becky’s Lines&Squares.
Update: I thought this was bamboo, but Tony Tomeo has advised in the comments that this is some form of palm, perhaps a large species of Chamaedorea (bamboo palm). Golden cane palm (Dypsis lutescens) might be another possibility.

They’re pretty but they look like something that only belongs in the tropics – even though I know it grows outside the tropics.
It wouldn’t stand much chance in Darwen!
That is not bamboo. It is some sort of palm, like a large species of Chamaedorea. Some Chamaedoreas are known as bamboo palms.
