Phyllostachys aureosulcata ‘Spectabilis’

Phyllostachys Spectabilis quick facts:

  • Running form of bamboo

  • Average Seattle-area height: 20-25’ (in ground)

  • 1.5 -2” dia canes

  • Full sun - partial shade

  • Can handle high winds

  • Cold hardy and evergreen

  • Adapts well to containers

  • Dense growth provides total privacy

Phyllostachys aureosulcata ‘Spectabilis’ is a fast growing, vibrant and colorful running bamboo for a Northwest privacy screen. It can rapidly fill a raised container with bright yellow, green pinstriped canes that blush magenta in sunlight their first season.

Spectabilis [along with other forms of Ph. aureosulcata] thrives around the Puget Sound and produces vigorous growth despite the normally cool and rainy Spring weather.

Growth habit

Ph. ‘Spectabilis’ is a running bamboo that requires a strategy for containment. Rectangular planters and large pots can be easier routes to a privacy screen vs. installing root barrier in the ground. It’s very important to do some forethought and study or consult a verified local expert before planting running bamboo in the ground.

Like all Phyllostachys, Ph. ‘Spectabilis’ produces new shoots annually that develop into full size canes within two months. The new canes branch out and create a dense canopy of leaves over the years.

The quality of the canes lack the tensile of true timber bamboo. They have a cat tongue texture and lack the oak-like strength and wall thickness of other Phyllostachys. The trade off is that it develops notably faster than timber bamboo.

Whichever size you start with will typically attain 3-4’ of height each year until it becomes limited by the size of the container you plant it in. Larger planting areas beget larger canes. Spectabilis bamboo takes 4-5 years to attain maximum height. Beginning with a medium sized/mature pot of bamboo will generally get you there a couple years faster.

Depending on your patience vs. urgency to provide a screen, running bamboo plants can be spaced every 3’ - 6’ and will eventually fill in. It takes 3 summers before for a privacy hedge to start filling in, but it’s still among the fastest bamboos in the Puget Sound region to establish and thrive.
