Turkish Red Giant sounds pretty awesome, and a good keeper too. So far, I'm finding the purple stripes to be the best keepers (but maybe due to being small bulbs I've been growing up).

Yes, most people are planting the bulbils in the fall, same time as garlic. Tiny ones can be broadcast and doesn't matter if they are upright or not. If I have larger ones, I space them out evenly and plant upright for best results. They are planted shallower than a large clove of garlic - I use the same rule of thumb: depth = 3X the clove height of soil above the clove.
