QR Code Link to This Post
A true collector’s bamboo, this rare clumper has four-sided culms instead of the usual round canes. Along each internode is a distinctive yellow sulcus that emphasizes the square profile. Unmistakable in appearance, it’s an architectural plant that always draws attention.
🎯 Fun Facts & Features
📐 Square Form – Culms are angular, with flat faces instead of round stems
🟡 Yellow Sulcus – The golden groove running along each internode highlights the shape
🌿 Clumping Habit – Non-invasive growth makes it manageable in smaller gardens
🌏 Rare Species – Native to China and almost never seen in regular retail trade
✨ Conversation Piece – One of the most unusual bamboos you can grow in the PNW
🍂 Why Plant Bamboo in Fall?
Fall is the best time to establish bamboo in the Pacific Northwest. Cooler temperatures and regular rainfall reduce transplant stress and encourage strong root growth before spring. By next growing season, your bamboo will be well rooted and ready to push new shoots.
