Nutsaboutnature's suggestion of zinnias does satisfy several of your requirements:

(1) Able to grow from seed broadcast in spring or lightly cover seed.

(2) Easy to grow and tolerant of your climate.

(3) Some varieties are about 24 inches tall.

I breed zinnias as a hobby, and they are capable of good white blooms. By saving seeds from your favorite white specimens, you could upgrade the quality of your white zinnias each year.
