Rainbow's End is one of my favorite miniatures, having the color, form, and bloom power needed to make this a serious pleasure to grow. You can't go wrong using Rise 'n' Shine as a parent plant, and Ralph seems to have loved using that legendary yellow as a parent (perhaps his replacement for Zee once it was lost to horticulture history?) - had he been given the rights to Rainbow's End it may have been one of his crowning achievements in breeding.

A few thoughts on the plant. It has fairly proportionally shrunken foliage, a hallmark of Moore's breeding. Too many modern minis have awkward, giant leaves topped with mini-sized blooms on a somewhat stunted habit that make for a plant that looks jury rigged and outright goofy. This seems to plague some of the Sunblaze miniatures. While Rainbow's End doesn't have the teeny-tiny leaves of some of the classic minis, they are certainly small enough to keep the overall aesthetic of the miniature rose bush. The bush itself can get quite large if you don't manage it's size with good deadheading. This can be a good thing if you want it to be (as a feature specimen or covering a foundation of a house), as it blooms almost nonstop from spring to November. I was getting blooms on one of mine several weeks after the other roses had stopped blooming, and that was with about only 3-4 hours of sun a day. If you get as little sun as that plant does for me, the roses stay mostly yellow with the pink edging which is fine by me.

The real magic, however, comes from having blooms in every stage in the color cycle on the plant at once. Yellow, pink, red, and white make a Rainbow's End in full bloom one of the most spectacular sights a rose grower can behold. Every one of them holds in a nice high center for quite some time as well, you might not win an exhibition with this (like you would with Winsome) but the staying power makes it a close race. There is not much fragrance on this but if you get a whole cluster opening at once you can usually get a small whiff or two, not unlike the "wild rose" scent that Poulsen describes many of their minis as having.

Some people talk about this rose having disease problems but it totally depends on local conditions. I have all of mine on a covered porch where it doesn't get rained on and I never saw a hint of disease on them. I sprayed perhaps 2-3 times last year after high disease pressure (blackspot on one plant and powdery on another) but that was preemptive. The health was a pleasant surprise after reading a few people's reviews saying they couldn't keep it clean. Even if you have it in a spot where it requires regular spraying, however, the immense reward the plant gives the attentive gardener is WELL worth it. I can't overstate how impressive Rainbow's End in full bloom is. Easily one of my top 10 roses regardless of category.
