Rhubarb Glaskins Perpetual (Rheum rhabarbarum) - 50 Seeds •Heirloom •Non-GMO •Open Pollinated •American grown seeds •100+ Days •USDA Zones 3-8 Description: Looking for a delicious and reliable rhubarb that you can enjoy all season long? Look no further than Glaskin's Perpetual! This old-fashioned favorite is perfect for pies, tarts, jams, and even wine, and it grows quickly and reliably. Plus, its low concentration of oxalic acid makes it perfect for late-season harvesting. This is our favorite rhubarb by far. Growing Instructions: In full sun, plant it in a permanent bed or large container (in shade, it will grow slower). You should prepare the soil with lots of compost and space the plants 3' apart. The second year, you can pick some stems (clip off flowers if they appear). In the third year (and for the next 10-15 years), you can harvest all but 4 stems per plant. Pull the stems off with a twisting motion instead of cutting them with a knife.
