I ordered some native bluebell seeds by accident from ebay - I thought they were bulbs.

Anyway when they arrived they were seeds :confused:

I allways thought bulbs multiplied by 'spreading' only.....

Do they casts seeds that evolve into bulbs, and also 'spread' as well :confused:

Yes - they can do both.
The bulb is just a clone (simple terms) of the mother bulb. They have seeds aswell so that gene's get crossed over and hence evolution can take place etc

I'm sure someone can explain it better than me :)

I agree with Torin, as I understand it the bulb production is an example of asexual reprodcution (cloning) where the DNA is identical to the maternal DNA. Seed production occurs after pollination and is an example of sexual reproduction where the DNA is a mix of both the maternal and paternal DNA(allowing for greater genetic diversity in the population).

It's like the difference between mitosis and meiosis in diploid genetics if that's any help.

In other words, yes, you can plant them and they should grow, lol.

Big question, though...where did you get the seeds from? A reputable supplier, I hope?
