Pleioblastus variegatus Intense white and green variegation give this running bamboo a great look. Foliage is persistent here in zone 6 usually at least into or through December. It is an extremely vigorous spreader and should be strongly confined where ever it is planted. Keep this plant away from a mixed planting where it can take over in time and be very difficult to eradicate. Pleioblastus pygmaeus This running bamboo has green willow-shaped leaves. It is considered invasive. Can be used in a container, or a difficult site where it will seem to thrive on neglect. Just keep it confined.
