Centennial Hop Rhizome

I started growing this half way through the growing season so I wasn't expecting it to grow to full size. However, it isn't growing well at all. I have been taking care of it well, keeping it watered, plenty of sun, and nothing to bother it, but it hasn't grown more than 18 inches. It hasn't grown in over a week and I am not sure if it will continue to grow. We will see how it goes next year.

Product arrived in good condition and took off right away.

Grew like promised

Failed to germinate. Ordered two others from another seller and those are doing great.
