Anyone know what type of bamboo this is?
Please ID bamboo
Does it spread or remain in its clump?
Hmmm don't know myself but it looks very nice :)
If I am seeing this correctly, it looks like the culm joints contain a central branch with several smaller branches around it. This may point to Bambusa. Maybe Bambusa vulgaris.
Can you show some close-ups of the culms and brances?
