Pagoda is an Erythronium hybrid. But your description of the seeds sounds like true lily, or Lilium. I can't explain that.

To grow Erythroniums from seed, you will need to be patient. It takes 3 or more years for them to bloom from seed. Sow the seed in Fall, in moist potting mix at around 60-65F. After about two weeks at this temperature, they are ready for winter chilling at around 40F. This can be outdoors or in the fridge. Do not allow the potting mix to dry out at any time. I place my containers in a sealed plastic bag, to keep them moist. The grasslike seedlings will germinate in early Spring, and will need lots of light to produce healthy bulbs. I grow them under fluorescents at around 55-60F. I fertilize with bone meal and soluble plant food. In a couple of months, the seedlings will go dormant (the foliage will turn brown). This is a clue that no more water is needed. If the dormant bulbs are stored in wet soil and warm temps, you may lose them all. Store the container with the mix and the tiny bulbs in a cool dry place until Fall, then water and place in a cold (40F) place until Spring. The plants will emerge in early Spring and need the same treatment as before. The container can also be plunged into a partly shaded area of your garden, but this is risky because of slugs and other pests.

Lilydude, thanks for the advice. Since the erythronium grows wild here, I thought that I should try to copy our natural weather patterns but in order to get a better survival rate, protect the young plants. I have never had good luck with seeds but I have been reading the winter sowing forum on G/W and think that I will use some of their tecniques. I appreciate your explanation -- there's nothing like having someone who has "done it".

If you have a lot of seed, you can just broadcast it in a partly shaded area that doesn't get a lot of water in Summer. A few years later, you will have flowers. Survival using this method will not be as good as with the container method.

That is what I think so I'm going to try the container method so tht I can give them some TLC to get them started. I dug up the pink erythronium from my Mother's garden when she moved in 1986, planted it in a wild area of our garden and it has now spread to give me more than 30 flowers each spring. They are so lovely it certainly is worth being patient. Thanks again for your advice.
