The penultimate Poker in our opinion at this particular moment. Tall wands of orange tubular flowers well spaced on the stem echo images of Aloes in Southern California. These 5'-6' flower stems start in July and continue right up until frost. This is a sterile form so it sets little or no seed and since it never manages to consummate the procreational act, it keeps trying. Personally I am in awe of its stamina. A good spreader which quickly makes a clump. The leaves are much shorter than the flower stems and thin-bladed as well as being deciduous at least in our climate. This may not be as hardy as some other species but is worth every effort to make happy. We mulch ours for the winter and that seems to meet its needs. This triploid form was recently given the clonal name 'Stern's Trip'.
