Lily bulb scales make new bulbs - with patience and time
Lily scales in a plastic bag with dampened vermiculite and seed starting mix.
Pinch the opening, blow into the bag and seal with a twist tie.
Keep away from sunlight.
After 3 weeks, dump out the bag contents and sort it out, removing the scales and spoiled bits from the starting mixture.
After removing all the outer scales, I put the central basal plate into the bag to see what would happen and they rooted.
Here's a typical lily scale with a bulbil growing off the basal plate end.
I tucked a few slices of daffodil bulb into the bag to see what they would do and they all turned to mush.
About 25% of the lily scales were mushy on their growing tips.
About 25% of the lily scales did not grow a bulbil.
