Ranunculus is a perennial plant in zones 7 and 8. Otherwise, they're annuals and you will need to dig them out to grow indoor for next season.
It is best to plant ranunculus corms in the fall before the ground is too hard from the cold. It all depends on your zone, but for zone 8b, we plant them in October or November.
I will be honest, they can be a little tricky, but easier if you start them indoors. The reason they are a little hard to grow has more to do with the soil and weather.

This is super important, you must have well-draining soil or like dahlia tubers, they will rot. Make sure you are using a very high-quality soil mix. You can add perlite or some type of sand mix to improve the drainage of your soil.
The flower looks fragile and soft, but do not overwater them. Keep the soil moist and try to avoid getting water on the leaves and flowers. Water around the base of the plant first thing in the morning, so that the plant has time to dry before evening.
I would not consider them invasive, though the corms multiply so you get more plants to form one at the end of the season. Do keep in mind that they self-seed and will spread in certain conditions, not in an aggressive manner.
