All chrysanthemums are perennials in horticultural zone 5 - 9.  Perennials being plants that can live (and rebloom) for more than 2 years. However, the best blooms come from chrysanthemums that were freshly planted in the spring.

Chrysanthemums prefer full sun for a minimum of 5 hours daily during their growth phase. If your area gets less than 5 hrs of full sun, then it might trigger early bud formation. If you live in an extremely hot area, some light shading could be beneficial in the afternoon

Chrysanthemums prefer good drainage and do not like extreme moisture. If growing in pots, water when top 2" of soil is dry. If growing in ground, water about 3 times a week. In hot weathers, you might have to water daily.

In winter time, you should cut the plant down to ~6" tall to encourage new growth in spring. During the growth phase, chrysanthemums are trimmed for the purpose of shaping the plant and to encourage the type of blooms you want. This is mostly for growing show mums and/or cut flowers for arrangements.

You can absolutely just let it do its own thing!

Chrysanthemums prefer high Nitrogen fertilizers. Whether you go synthetic or organic is up to you!

Most of our plants are sold in 2.5" pots, some are in 4" pots. We are a non-profit, so all the proceeds goes to supporting club meetings and organizing the shows. We appreciate your support!

Unfortunately, we only have one plant sale a year. So if you're looking for a specific specialty mum, you'll have to wait for next year. But you can check out some small growers that we have purchased from in the past and see if they have what you're looking for in stock. Keep in mind most plants are sold in the spring.
