Limey Lisa may be the wrong color--it's bright in the spring, but gets considerably more green as the season goes on. I have two other possibilities. Ophir, which is bright gold when it comes up, but quickly turns chartreuse, is a medium small size with an upright habit plant and beautiful long, very wavy leaves. Little Razor is chartreuse all season, has an interesting plant habit with rather upright leaves that are lance shaped, and it grows like a weed. It's a cross of Venusta and Sum & Substance, and got it's small size from Venusta and the chartreuse coloring from S&S. It is larger than Venusta, with a mature plant being about 8-9 inches tall. Little Razor also makes a good edger. Either of these varieties will take full sun. Gold Edger will turn a very pale gold color in full sun, but otherwise will do very well as long as it's kept well watered. It needs some shade to keep it's gold/chartreuse coloring.

I love abiqua drinking gourd hosta next to my kossa regal. It is tall enough to not be overshadowed by the kossa regal but the cupped shaped leaves make it look very different so as not to blend with it. The blue colors complimet each other so as not to compete or look garish. Here is a link that might be useful: abiqua-drinking-gourd

I thought of Teaspoons, but it is unlikely that the seller wouldn't have known what it was--that variety is very distinctive, especially as an immature plant. Can you tell us how much substance it has, and also where you purchased the plant? Too small to be Candy Hearts, which has much larger leaves, even as a young plant, and in three years CH will be 20 inches tall. It doesn't look exactly like my Jade Sceptor, but all the Tiara series is somewhat variable depending on growing conditions, so that is a possibility. It does have some resemblance to Nakiana, but unless you bought it from a hosta nursery or grower, that's unlikely.

Mocc, thank you for noticing Jimmy Crack Corn! Yes, it is now growing in the ground, a little over a month. When I bought it the summer of 2013 it already had been grown on a year in its nursery pot at Hosta Fever. As you can see from that pic, the leaves were still fairly adolescent although they were large...rippled edge apparent already. It remained in its nursery pot over winter until early this June, when I finally planted it. It receives direct sun from sun- up until 2:00 p.m. and obviously is very happy there. I love the substance of this one and it is taking on more gold. That colour is bang on! >> first pic is current, in ground >> second pic of JCC growing in pot - leaves looking same as in ground >> third pic of 2013 new acquisition but showing some characteristics I hope I've answered your questions, Mocc. It was the gracefully rippled edge and colour, and size of leaf that drew my attention last year. It's attributes are unusual in a golden-yellow hosta. I just had to have it! :-)
