Sun Flare?

Don't think it's Sun Flare. Sun Flare has larger blooms, and a fragrance. In the Rose Gallery I just looked up a post by Kathy9norcal called: Living in the land of minis. The one she labels "Just a grocery store mini, a pure yellow I love " looks just like this one. Although this is 3'x3', I've been suspicious of it being an overgrown mini as there were two other mini's here (the only roses on the property), and I'll bet all were grocery story Mother's Day presents...

Julia Child, maybe?

Nope. Have a Julia Child, and JC's blooms are easily twice the size of these, and do have some fragrance. I've never detected the slightest hint of fragrance from this guy. These blooms have an actual size of a little over 1", and that's it. I rechecked bush size and although it has gotten to about 3' tall, it is quite a bit more narrow in width.

It is not Sunflare.

The growth habit looks a little like my Golden Rain, but the flowers seem more double.

Could it be Sunsprite? I think Sunflare is a seedling of Sunsprite, which would account for the similarity in foliage between the two. Sunsprite was sold throughout the USA for at least a decade after its' introduction.

I have Sunsprite too. Very fragrant, and blooms 3x the size of this one's.

Definitely not Sunsprite or JC. I grow both, and they are both very fragrant, and have flowers far larger than this rose. (Size aside, the shape and color of the flower do look like Sunsprite.) Also, once established, Sunsprite should be a lot of taller than this one. My second year, grafted Sunsprite is about 4' or 5' tall now.

Sequoia God, Y2K or rise & shine?

OK, I didn't realize it was a mini.

It's not Rise n Shine because the petals reflex into that star shape as they age on that one.

And I don't think it's Y2K because that one can get a pink blush on the petal edges.

It might be Sequoia Gold but it's hard to say.

Yeah - mini or non-mini - that's still up in the air. I have this gut feeling I'm going to end up having to call it Yellow Mini (?) forever, as the only few photos I've seen on the internet where the blooms look alike are labeled Yellow Mini. I looked up Rise N Shine, Y2K and Sequoia Gold, and alas - blooms don't look like any of them. The closest named rose I think I've seen is Lemon Drop - the new blooms look very very similar, but the aged blooms do not. It's aged blooms look exactly as they do in the 2nd picture - you never see the stamens before the pedals blow. And the pedals stay on a really really really lone time (up to a month). I do know this search has given me the opportunity to look at lots of gorgeous minis that I wouldn't otherwise have seen...

It could yet turn into Sunsprite given water and fertilizing. If it has been neglected for several seasons, it might not be able to put out large blooms.

If it was a grocery store mini, it would not have come from Sequoia. Might be from Paulsen, in Denmark. I think that is where Trader Joe's minis come from.
