Check for disease resistance before you decide on rose varieties, unless you are willing to spray weekly with some pretty environmentally unfriendly chemicals. Yellow roses tend to be even more susceptible to black spot than others. I don't know if rust is a problem where you are. If you must have yellow, consider "Lady Bank's' rose. An old garden rose with terrific disease resistance, a prolific grower, and easy to root from cuttings if you want to buy one and start the rest of them yourself. It blooms only in spring.

Suggest you go to your local library and research before deciding on what kind of roses to plant, especially if you are talking about a whole line of them. For disease resistance, consider 'landscape' roses such as the Knock-Out or Explorer series. Don't rely on catolgue descriptions regarding disease resistance.
