Have you checked these guys out? http://boughennurseries.net/index.php?pageid=8&categoryid=15

I looked at their address - are they in Canada? Overseas?
I don't think they are in the US but thanks for the suggestion anyway.

Mum General Information:

Chrysanthemum are Queen of the Fall Flowers. Few plants can rival mums for beautiful fall color. They begin their show in early autumn and are handsome until a killing frost. Allow plenty of room, these plants will reach full size and flower prodigiously their first year.
Mum Plant Care:

Prefers compost-enriched well-drained soil. Good drainage is a must for successful overwintering. We tip the plants back before shipping to promote bushiness, but any strong shoot which is getting ahead of the plant should be tipped back. (Remove the growing tip.) Do not pinch after 4th of July. Can be divided in spring if needed or if center of clump dies out. Mulch for winter protection only in very cold areas and be sure to remove it before the spring thaw. Clean up old foliage in spring and cut back to new growth.

I know they used to sell the white ones but when I saw they only sold the yellow one now - which is cute too - I didn't think of calling to ask if the white might be available next year. I placed an order from them earlier this year and have ordered from them before.

When I don't see a plant listed that I want, even if I know they sold it in the past, I just give up and don't pursue it any further.

Thanks for the suggestion. I'll give them a call.
