After a few years growing Lady Emma Hamilton I feel comfortable enough to talk about its performance. I bought it in summer 2018 as a grafted plant (probably on R. laxa) in a pot and planted it in the ground during the following winter. I think that its flowers are the most variable due to weather conditions out of all of my roses; the first blooms to open in May are solitary and medium sized (about 7/8 cm), with about 70 petals and peachy pink (definitely not orange). On the second flush (first days of July in my climate) the flowers are held in medium sized clusters of about 10 blooms, smaller (about 5cm) and just a bit more than semi-double (about 30 petals, but they keep a cup shape); the color starts as a tangerine orange, slowly fading to an attractive translucent pink. I think that her blooms may get flatter in shape in really hot climates, but keeps her cup shape in my climate. Blooms last about 5 days and they are definitely not prone to balling. Its fragrance is always strong and delicious, tasting like mature green grapes during spring and more like citrus (but more like oranges or tangerine than lemons) in hot summer days.
In regard to the shrub shape, I find Lady Emma Hamilton to be unique, since it starts getting broad and only after a couple of seasons it gets taller. I suggest everyone who is disappointed by its performance in the first couple of years to give it time: you will be rewarded. I don't think the problem is lack of vigor, but to really appreciate its beauty you should wait for its basal canes to grow vigorous laterals, and this requires time.
My Lady Emma Hamilton is very thorny on the main canes (it has a lot of prickles, but they are small and not extremely sharp, so it's not much of a problem), but is almost thornless on the laterals.
I thin that in order to really appreciate its blooms you should feed it quite often; I can't really say about watering, since my climate is kind of rainy, especially during summer, and I don't water her at all.
It reblooms quickly, producing 3 main flushes in my garden (mid May, beginning of July and October) with scattered flowers between.
Even though I live in an area with high blackspot pressure, it does well in my no spray garden. It does get some spotting late in the summer, but seems unbothered by it and retains all of its foliage.
I'm a rose hips lover and if left to Lady Emma Hamilton will produce many of them, but they are rather unattractive, remaining green on the outside with only some red spots; they look like they have been cut in half, since there are often seeds growing outside of the hip.

If you are interested in hybridizing, Lady Emma Hamilton is fertile as a seed parent and have a decent germination rate (about 30%), even thought its hips do not carry a huge number of seeds (about 4 or 5 on average). It passes her bronzy foliage on to many of her offspring

I would like to know if anyone growing LEH in a rainy environment has experienced this one balling in wet weather. I hope someone could chime in on this, because it’s the one concern the Southeast US and the tropics would have as a concern. I would say that balling is almost worse than an attack of BS.
Thanks for any input.

This is year four for LEH in my garden. I have loved her from the beginning, even through an early scare with spider mites that took half of her in the first year before I knew what was happening. Since then she has not only recovered, but spread to around four feet in width and a height of around three feet. She gave me two new canes last year and another this spring. She is currently covered in buds, having opened only two flowers so far, which puts her as my latest of the returning roses. She vies with Munstead Wood as my most floriferous rose. Beautifully complex color range, intoxicating citrus fragrance, beautiful dainty, bronze new foliage, and little disease, usually confined to a bit of BS going into the fall. I understand some have had trouble wintering her in Northern Ohio, but I have her in a very sheltered spot where, with no special protection, she has come through two very fierce winters (those immediately preceeding this last very mild winter) with die-back to the snowline and a quick recovery. Outstanding rose in all respects.
