It should have white flowers with just a hint of lavender, very fragrant. It is the first patented hosta cultivar in 1965. I can show you the whole blurb from the Hosta Handbook if you would like.

In southwestern PA, my Royal Standards don't even have scapes yet. They usually bloom in late August and are so fragrant they are absolutely unmistakeable.

there are VERY VERY few hosta that have pure white flowers ... and plantiginea is one of them ...

it is though that all fragrance come from the species plantiginea ... but on the crossing of pollen.. the progeny lose their 6 inch PURE white flowers... down to 3 to 4 inches.. and just about ALL HAVE SOME PURPLE ...

some only in the bud phase ... and they fade to white on opening .. others just dots way deep in the flower ...

if you think you have a hosta with pure white flowers.. you might want to go out there day after day.. and study them from formation to dead flower.. and 'see' that they are not pure white..

go figure..learn something new every day .... otherwise you are probably dead ...

My dear old granpa used to say, "Some people live and learn. Some just live."

Here in Minnesota, Royal Standard blooms in August, and the flowers are incredibly fragrant. You might have Undulata Erromena. They look similar, but UE blooms earlier and has purple non-fragrant blossoms. Another possibility is Honeybells - less fragrant than Royal Standard and more purple, but it should still bloom in August, not now.

All that being said, if your flowers are not wonderfully fragrant, you do not have Royal Standard (in my experience anyway).

Have fun with your search.

Thanks for this posting. It let me figure out about my semi-NOIDS that I have 4 RS, one Honeybells, several Elisabeth and one Krossa Regal. I thought I had no KR, bought 4 last year, but now had planted two together, will do that to the other 2 KR too. One of those RS will be replaced by one KR - 3 of one kind is enough. Still too many Elisabeths.

Here is a pic of my Royal Standard, as identified by Chris @ Hallson's. Just finished blooming mid-July in MO.

I can see it having bloomed in July in Missouri, obviously, but in Minnesota it shouldn't even have buds forming yet. They aren't here in Northern Ohio, not until August.

Here a few photos of what I have...could be the undulata erromena that was mentioned.

This plant is old, I remember it from when I was a kid 25 years ago, and this is a division.

Thanks for the ideas.

I have several hosta with shiny mid-green leaves with curly border, blooming light lavender now, I think they are Elisabeth. Royal Standard is to bloom later white.

Hostamedic, the last pics you posted look like my Erromena. The leaf color is just a darker green than Royal Standard, and the flowers are lavender. Mine have bloomed as early as June, and sometimes twice in a year.

I have them growing alongside Royal Standard and can tell the two apart by the green, bloom time, and bloom color.

Here is a pic taken July 7 that shows RS on the far left corner, with some Erromena behind (you can see their flower stalks above RS) and to their right (the metal cages in front of them are for the lilies). Anyway, the color difference is easy to see here:

Eleven, can you do that picture again? TinyPic was presenting a problem for a couple of months now, which is why I've changed to Flickr. I'd really like to see the picture for comparisons.

I have a Royal Standard and many other plantaginea progeny. However, no Erromena, no Elizabeth.

Here is my RS alongside the Fragrant Blue, taken last week.

I can see Eleven's photo just fine.

How strange, Babka. All I see is a statement:
"Image and video hosting by TinyPic."

when I click on it, it takes me to the main Tinypic page.
This is happening on my new computer, just like it did on my old laptop.

I just sent a note to Eleven to send me the picture via email, and when I came back to this window, THERE THE PICTURE WAS VISIBLE TO ME....

I do not understand all that I know.
Cancel the request, Eleven....sorry to bother you!
