daisy_lee - sorry to rain on your parade but L. 'Banana Cream' is a sterile cultivar in my experience so even if it produces seed and you harvest them/trade for them, they may not/likely will not germinate. If you hope to add more Shasta daisy cultivars to your garden beds, check out Swallowtail Garden Seeds' website (see link below). They offer relatively few which suggests those you listed are not viable from seed and must be propagated via division.

Of those listed above, 'Crazy Daisy' can be grown from seed--I winter sowed it in 2010 and it bloomed beautifully this past summer. I might have harvested seeds to share.

Thanks for taking the time to write! I just found out that some of the plants don't produce seeds when I harvested nothing but chaff. I looked online and found a lot of the ones that I was interested were sterile, so I took them off of my Want List but didn't know how or if I could edit the above post. Thank you!
