I've had such great experiences with Heirloom. I purchased Florentina a couple months ago and though it arrived looking healthy, it began dying very quickly. Heirloom issued me a credit immediately and I purchased another. It is big, thriving, and very healthy so far. A lot of new growth already I just a couple weeks.
14 acres of roses (over 700) and this one is one of my very favorite. She is very disease resistant in my zone 9a humid climate and puts out long canes of flowers with about 15 flowers on each. The flowers are very long lasting. One bunch can fill a vase. Not heavily scented, but makes up for it with her gorgeous quartered flowers!
I planted these end of May from rose only and by June it had tripled in size and I had my first bloom!! Since then it is now about 6-7 feet tall and has overgrown the trellis! It is also very full. The lush and thick quality has surpassed my expectations. And for the record I do not have a green thumb!!
