Mystery Plant

At the South Seattle College Arboretum I saw this very different looking plant. I tried to figure out how to google this plant. Big leaves. Pineapple like stalk. Spiky. Zucchini leaves. Fluffy white pink flower. Exotic. I don't know how, but I found it.

Here is a more professional description:
Giant Rhubarb is a unique offering that produces whopping 6′ leaves that are distinctively patterned with deep veins and coarsely toothed edges. This exotic focal point is ideal for damp or boggy spots. ​The underside of the leaf and the whole stalk have spikes on them. In early summer it bears tiny red-green flowers in conical branched panicles, followed by small, spherical fruit. However, it is primarily cultivated for its massive leaves.
