Question
I want to grow long stem roses. Where do I buy the plants to get started
I live in zone 5

Answer
The florist type long stem roses are grown in a greenhouse through a wide wire mesh and that keeps the stems upright and makes for longer ones. Plus they clip them a certain way and disbud. The garden roses just grow their own way, which means they can have long and short stem blooms on the same bush. Your best bet to find what hybrid teas do tend to have long stems, is to go on a rose forum and ask people who garden in your area. Here is the best rose forum.
