Collection and Germination of Scilla madeirensis seeds
My Scilla madeirensis bulbs flowered well this year and I would like to harvest the seeds to produce new plants/bulbs.
The bulbs are in my greenhouse for the winter with the leaves slowly drying and the seeds still on the flower stalks.
I have been waiting for and expecting the seed "pods" to dry and shrivel so I can collect the seeds. However, the pods remain a plump, healthy green colour and I am wondering if this is the how they would remain in their native habitat, possibly waiting for whatever "animal" normally eats them as their means of dispersal.
I would appreciate advice on the best means to harvest and germinate the seeds.
I have removed one green pod and inside there was a single black seed (approx 5mm diam) with a hard coat.
Should I remove the seeds from the other pods now while still green?
Do the seeds need to be stored over-winter ready for sowing next spring?
Do the seed need a "cold spell" to help with germination? (I presume in Madeira they would not encounter freezing conditions)
Should the seed coats be "chipped" before sowing to help germination?
What conditions are suitable for germination?
Any advice would be welcome as I really enjoy these bulbs when in flower and would like to propagate more.
