Did you leave any scapes on the plants? You mentioned that you'd planted some bulbils, do you remember how many and size and shape of the bumbles per umbel? Purple Stripe bulbils are small rice grained and numerous often with lots of flowers. MPS bulbils much larger and 50-100 per umbel. Standard PS have more cloves per bulb and MPS fewer cloves that are fatter. Here's a good reference site with photos of whole bulbs and cloves to help decide on varietal group.
