Here's a picture of some of my Golden Tiara (the hosta on the left edge of the picture). You could use them for reference. They are as big as they ever get and could use some dividing up. I started with quart sized plants though, not little ones like yours and they were named when I bought them. They do look similar. I have not noticed them throwing seed however, just reproducing with more roots. You might try the American Hosta Society registry and measure the leaves and count the veins and whatnot to back up your possible id.
Gardenmart, those are very nice looking hosta beds. My 'Golden Tiara' will require dividing this fall too.
Kiseta, I don't see that blue flowering plant in garden centers any more. It's a salvia called 'Blue Peter'. If I remember correctly it blooms late May/ early June and it tolerates some shade in my zone 5 garden. The blues that are blooming in my garden right now are the campanulas, blue clips and campanula perscicifolia as well balloon flower 'Sentimental Blue'. If you want to discuss blue flowers any further, I suggest that you start a new thread about blue companion plants for hostas.
Irene, remind me, if I ever get that way to see your garden, to bring leaves of these plants. Sandy saw them the other day and thinks 'Golden Tiara' is a good guess too. So, they are tentatively named GT.
Thanks. The bulk of the picture are my mini hosta beds I haven't taken a picture of many of my hosta this year except for those beds as I have added some to them. The GT are in a larger bed that have daylilies, iris, columbine and a tree peony in it. they are the border. Haven't changed that bed since I put the tree peony in a couple years ago.
