" I live in southwest Fort Worth, zone 7A or 7B (that close to the
line), and I need a little help.

Both the Dallas and the Fort Worth Rose Societies are extremely helpful
in indicating what roses are suitable for the mid-Texas climate. I seem
to recall seeing Blaze and Don Juan all over the place. However, you
can more specific help than that. Just go to the Dallas Rose Society
home page--www.geocities.com/dallasroses/
where they have an icon for 'What roses do well in this area.'
