I've had a Neptune for 3 years and it does very well in my garden. I love the dark green foliage and large and VERY fragrant lavender blooms. Japanese beetles love the blooms and ruin all of them if you're not proactive about spraying and picking them off.

Mine is planted in full sun on the south side of the house. Blackspot can be a problem but mine does well if I spray sulphur at last frost and pull the affected leaves quickly. I pull them everyday when I get home from work before going inside.

I have counted as many as 80 buds on this plant at one time!!

Bottom line, this bush takes a little bit of work and for it, you will be rewarded with beautiful roses with an amazing scent.

I tried this rose a few years back. I have seldom had a rose that grew and bloomed so poorly. I think that in one summer I had no more than three blooms on this bush -- for the whole year. And the color was not the beautiful lilac color that shows in the pictures people have posted here; mine had flowers so pale that I would literally call them gray.

I culled this one after one summer. Thumbs down!

This is a very gorgeous rose, with a beautiful lavender color. Very fragrant. Can be prone to blackspot if not treated early. My only complaint is that it doesn't last long in a vase, maybe two - three days max.
