They are all perennials (as far as I know).

All tropical orchids are perennials. Some temperate orchids are still perennial but may be deciduous.

I love the orchids I see at garden centers, Lowes, etc. Those are the ones I want to try and grow.

Most orchids in Lowes, HD and even grocery stores are called phalaenopsis. Other types you'll often see are oncidiums and dendrobiums. In my opinion - the types of dendrobiums you'll see for sale are quite difficult to grow without a greenhouse.

Where do you live?? Zone 7a is warm. Give a Phal or Dend a try. Pick up one at the store and bring it home. Post back and we'll help you get it going!
