I have one in Orange County CA near Disneyland. It's on Dr. Huey roots and has long arms. Repeat blooming has been good even though the plant has been in mostly shade with afternoon sun. I have not gotten any disease even though it is in a shadier spot. I also have Cinderella, Pomponella and Lion's Fairytale. I would say that Larissa fits with these in that the charming clusters of flowers come on a plant that grows larger than stated on the tag and has a more open style of growth than modern floribundas. What I had hoped for in Larissa was the multi pink flowers with the deeper centers, but because my climate is warmer, they are a uniform mid pink all over. The few times I had an extended period of low to mid 70s days I had the color I wanted. I think this is going to be a trouble free large shrub for someone who wants a landscape leave it alone rose. It is thorny so it might make a good security hedge where you don't want a really tall rose.

This sounds like a good rose for my "island plantings". I have a small pond with an island - this rose might fit in well planted where it can drape down a slight incline toward the pond. I had a water spigot put on the island so can keep it watered. I am not a fan of low growing sprawling roses, though I like the color of this one. Since its thorny, I think the island would be a perfect spot for it. The color looks really pretty.....taller shrub roses would look good behind it.
Thanks for the reply!
