Just remembered caryopteris 'Worcester Gold.

Veronica 'Aztec Gold' also has nice chartreuse foliage.

Heuchera Lime Rickey is another.

Tanacetum vulgaris 'Isla Gold"...frilly foliage which revels in hot GA sun...and our high humdity doesn't bother it. Easy to propagate from cuttings. Looks great in pot. Hardy Z. 4-8. I pinch off the yellow button flowers for more foliage. Foliage great filler for arrangements...lasts well and color so useful. One of my new favorites! josh

Here is a link that might be useful: Tanacetum 'Isla Gold'

Geez, just remembered another one-- Sedum Angelina. That Tanacetum looks lovely!

That sedum repestre (angelina) is cute..... I also like the cultivar blue spruce...... I have to add them to my list..... :)

How about ol' feverfew.

Spirea 'Gold Mound' and I think one called 'Gold Flame" are more chartreuse than gold if in light shade from a taller shrub. Plus they have lovely coral-red foliage in fall. This is another easy to root, carefree from bugs/disease plant. And also good for filler in vases. josh

Here's where I am a real weirdo, I guess. I can't stand chartruese foliage, really, really, really can't stand it. Everything about it jars me, I think because there's so much yellow in it that it looks anemic, lol. I much prefer the bluer shades and purple/red/black.

I like the contrast chartruese provides. Kind of a spotlight.
Someone mentioned sum and substance hosta but in that same family I have a med. size hosta called just plantiginea (sp?) that is full sun tolerant and even more chartruese than S and S,

Xanthosoma lime zinger is new to me but what a show stopper!

I'd love a chartruese canna. Is there such a thing?
