NHBabs, I got the fern at the farner’s market from a native plant seller and they have it tagged as Osmunda claytonia, which prefers drier conditions than other Osmunda and can tolerate up to 40% sun. That was an earlier-season picture when it may have been at its brightest but it generally holds that light green color all season.

Based on Missouri Botanical the correct name is Osmunda claytoniana, which is just the standard not a special named variety so maybe I got lucky with the color? Or maybe more sun helps lighten it up?

Mxk3, no, it was the wrong one. The one I thought that I ordered is green with dark purple flowers. Mine is plain green with pale lavender flowers.

It’s quite bright, but I enjoy nicotiana alata ‘Lime Green’. It would be an annual for those under Zone 8, but it self sows nicely. Lisa

Oohhh. Lisa, I like that

Oooh yes, nicotiana langsdorfii - a tall but dainty self seeder...along with ,affinis, they are manstays of the summer garden. I am not a huge fan of acers...but the full moon maple - a.shirasawanum is a complete darling...and I am also enjoying a few chartreuse shrubs - philadelphus coronaria and cotinus 'Young Lady'..

For (much) less than full sun there is persicaria "Golden Arrows":

If we are talking about a shady area (and that has not really been made clear), then I'd include either of the two gold-leafed bleeding hearts Lamprocapnos 'Gold Heart' or 'White Gold'. And in my zone, I'd also include the hardy fuchsia 'Aurea' (sometimes sold as 'Genii'). This blooms for me from April/early May until well into fall.....as late as Thanksgiving typically.

WOW! Thank you all. :) I really appreciate all the time and knowledge everyone shared. I’ve got lots to look at. Thank you so much! I can’t comment on each wonderful suggestion, but I really appreciate it, and it was very helpful.

Also, I don't think anyone mentioned the large Aralia 'Sun King'. Terrific plant.

Yes! I have an entirely chartreuse garden snd Aralia Sun King is the star! Even looks good now post-frost!

Pelargonium 'Crystal Palace' and Geranium 'Rozanne' have chartreuse foliage.

" Geranium 'Rozanne' have chartreuse foliage. "

Really?? Mine is just as green as most other hardy geraniums....maybe just a slight bit of marbling on the leaves. But both 'Ann Folkard' and 'Anne Thomson' have very chartreuse foliage.

My Rozanne foliage is also “regular” green. This one is in part sun, not nearly as light green as the heuchera in the background:

Great plant though, prolific bloomer.

Also like Camp's suggestion of fullmoon japanese maple or Acer shirasawanum 'Aureum'. Beautiful chartreuse upright JM, I wish I had a spot for one.

In addition to Acer shirasawanum 'Aureum', there is Acer shirasawanum 'Jordan’ which is borderline hardy in my garden but in your zone should be fine. It keeps its really bright foliage color well. It wouldn’t be tolerant of roots drying out, however, like most J maples IME.

I like Helichrysum petiolare 'Limelight Licorice.' Photo is from Kelly Macdonald on Dave's Garden. It originates from Southern Africa. Sorry, I just realized it won't grow well for the OP due to it requirements of growing in USDA Hardiness Zones 9-11, Sunset Zones 16, 17, 22, 23, 24.

Jasminerose, Limelight Helichrysum/licorice plant is commonly sold as a an annual plant in areas where it is too cold to be perennial. So it can be replanted annually or Dillybean can try overwintering indoors in a pot of s/he is so inclined.

Thanks, NHBabs. It's a great plant and worth growing.

Here is ours this past spring (May 30th 2018)

And now as of today (October 24 2018)

I wish I had a spot for one.

ckerr007, I thought similarly ie no space for JMaples but if one is selective one can squeeze them in...I now have 5 JM in a small property...love them. They are such important members of our garden.

Yes, my mistake. It's Geranium 'Ann Folkard' that has the nice chartreuse new foliage...and purple flowers with a dark eye. You gotta admit 'Rozanne' is mighty nice even though her leaves are green.

Rouge, that’s an amazing tree, I’m quite jealous. We do have 4 JMs on our roughly half-acre suburban lot: an inaba shidare, crimson queen, viridis, and most recently a shishigashira. Spots are pretty full unless we take down 2 old street side silver maples i don’t really like and started over with some nice ornamental plantings anchored by the ‘Aureum’ like you’ve done. Hmmm, maybe a project for next year and a new post for advice....

Lots of great suggestions here! The only one I can add is nepta 'limelight'. I have several and love them. They stay fairly petite as far as nepeta goes. My Walker's Low nepetas got about 4' in diameter before I removed them. 'Limelight' gets about 1.5' in diameter and stays fairly short so is great for edging.

-Chris

I had never heard of ‘Limelight’ nepeta! Thanks! Cools plant.

rouge, that maple is lovely. I have a soft spot for JMs, so I may have to find a chartreuse one to squeeze in somewhere.

My third post with yet one more--can't believe I forgot it because it's one of my favorites--Tanacetum 'Isla Gold'. Yes, it's a tansy, but unlike the green one which is a Galloping Gertie, this one expands very slowly. I cut it back to the ground in summer when it blooms because the yellow blooms are virtually invisible and it's usually getting thin looking by then. It comes back with a great flush of that gorgeous chartreuse foliage.

I would just add that there is always room for a Japanese maple!! I have a tiny garden and a collection of 15 JM's. All grow in containers (some quite large) and I stage them around the garden in various places......according to how they look and how I feel at that moment :-))

Yep, I agree. Even this somewhat sceptical acer-owner has space for a couple...and not even the smallest palmatums but a largish Bloodgood and even larger coral bark Sangko Kaku...both in large pots. For a small urban space, especially a sheltered walled courtyard garden like mine, acers add that defined architectural anchor and instant lush maturity which is an absolute necessity in the usual hurly-burly mish-mash of my messy garden

Fantastic specimen, Rouge.

Half and Acre!? I am so envious as we have a "postage stamp" property in comparison.

I really should look into this ie growing JM in containers. gg/campanula, how often, say in this past season for example, that you have repotted (either because the maple is getting too large OR because the maple simple needs new potting material)?

“Fantastic specimen, Rouge”

I couldn’t agree more...Love it!!

Rouge, I pot up my maples as soon as I buy them.......usually :-) I have three small ones I acquired this season that have not yet been treated to this as it was too warm and too dry when I got them. After that they don't get any special attention (other than water and ferts) for typically several years - 3-5. Then, depending on size, they will get up-potted or root pruned and repotted with fresh soil.

Both of my shirasawanums (Aureum and Autumn Moon) need root pruning and repotting this winter. They are 2 of my oldest maples and in big pots but I can tell they need attention. Both needed watering more frequently than my other maples......an indication that the roots are filling the pot and the soil has been depleted. And neither developed much fall color......the leaves just sort of browned and fell off :-(( Probably should have done this last winter or possibly even before but manhandling and root pruning my larger trees is not my favorite task - hard work!! - and I tend to delay longer than I should. And winter while the trees are dormant is the best time to do this but also our rainy season and the older I get the wussier I become about working outside in inclement weather!!

btw, in my climate, these trees stay outside year round. And that is a major requirement for me as there is nowhere indoors or even with moderate protection I could store them!! In a colder climate, I would be restricted by both the size of the tree and the size of its container as to something that would be more portable and able to be schlepped under protection. It is tricky to move a 6'x6' tree in a 20G glazed ceramic pot anywhere, let alone move it indoors!!

(I wouldn't recommend leaving a potted JM outside all winter in any zone lower than 7.....and that's pushing the envelope. Their roots are overly sensitive to cold and any containerized trees will experience much colder temps around the root zone than their planted cousins would.)

Absolutely no need to add anything to GG's sterling advice...but we do both enjoy a temperate climate. In my minuscule garden, I had to move my acers around several times before finding spaces where they were out of the wind and the only spaces available was hard standing (so pots).. Despite having a tiny, walled garden, in windy urban east anglia, we get some terrific wind-tunnel spots...and having found a space, the trees have never since moved. They are in heavy, terracotta pots...with a classic straight-sided plant-pot shape...so every few years, I tip the pot horizontal, ease the tree out and saw off the bottom 3-4 inches of soil, throw in some fresh loam and push the tree back in place. 1 x 6month slow release fert and that's about it for me...but I do have the more robust and less fussy types of acer.

I favor frost proof glazed ceramic containers and have over the years acquired a great collection. But those puppies - especially the larger ones - weigh a ton when filled!! Terra cotta just does not last well here, except for the high fired stuff ($$), and is also very heavy when filled. So this time my fullmoon maples will be repotted into lightweight but large resin containers. Not the aesthetics I favor but a concession I need to make to be able to care for these properly.

And I do get help when needing to move the big guys. Some weight the better part of a hundred pounds between the soil and the pot. I can usually drag them but that is not always an option....specially those that I stage on blocks or lifts.

Beautiful pictures! What striking combinations you’ve come up with. That fuschia with ‘Miss Wilmot’s Ghost!’ Wow. Thanks for the inspiration. :) Love the euphorbias.

Wow, I agree those are all gorgeous! I think I like the fuschia with ‘Miss Wilmott’s Ghost’ best, too. Lisa

Why, thank you!

Just came back to this thread to get more inspiration, and I’m struck again with what amazing, helpful, sharing people you are! Thank you and thank you again. I hope that I can pass along what knowledge I have to others as you all have to me.

Aztec Gold Veronica (low-grower, sun-shade) was just added to my garden, along with the above-mentioned Aralia Sun King (tall--sun to shade). I'm so happy for this thread, as I am on a chartreuse kick these days!

My grandmother use to grow Ireland Bells in her garden. I have always loved them.... probably because they are cure, and also because they remind me of her.....

Lemon Candy Ninebark is beautiful.

Just found a rainbow spurge at Walmart, of all places! Its very chartreuse now, but supposedly will change colors as it matures. :-)

Violet snapdragon, I hadn’t ever seen the gold Veronicas! What a splendid idea.

sharon, Bells of Ireland are a favorite of mine, but I’ve never managed to grow them successfully yet...

deanne, I LOVE the golden ninebarks!

perma n’ posies, what a great find!

I love the golden leafed herbs. Along with the ones mentioned here already, I also have grown pineapple sage and hops flowered oregano. They have the added advantage of not being preferred by deer. Golden Delicious pineapple sage is bright enough by itself but adds startling coral-red flowers later in the fall. Although edible, I planted this with migrating hummingbirds in mind but it bloomed so late that nearly all of them had already gone. Perennial only as far as z 8, sadly. Hops flowered oregano has a multitude of varieties and species, such as dittany, Kent Beauty and Amethyst Falls. Strings of bracts, usually chartreuse with a tinge of rose or lavender, dangle from stems. Tiny flowers may peek from the edge of each bract but the bracts carry the show even after the flowers are gone. I like them for pots. Good for drying. Zone hardiness varies.

A lot of Hostas have those colors

Fire island hosta, aztec gold veronica, limelight nepeta, aureum millet grass, Lil Miss Sunshine caryopteris, Hint of Gold caryopteris, Dart's Gold Ninebark, Neon Burst dogwood, Citronelle heuchera, Lime ruffles heuchera, Sun King Aralia, Dickson's gold campanula, Golden jubilee agastache, ajuga Golden Glow, Silene dioica Ray's golden campion, Veronica Sunshine, Gold Heart dicentra Bleeding heart, Neptune's Gold sea holly Eryngium, Lamium Aureum, Lamium Gold Frost, Glow Girl spirea, Sundrop spirea, Goldmine Phlox,

Creeping Jenny is a bit too invasive for me.

Japanese maples:

1. Koto no ito ('harpstring') in a bag pot for 3 years

2. Seiryu - only upright dissected leaves

Also Golden Hinoki cypress. I think mine would be more golden if it got more sun.

Lemon Candy Ninebark is beautiful.

I agree completely. Here is ours from the first week of June 2018:

I have to put in a word for Astilboides Tabularis. This is a baby one with it's first leaves, but google it. It is a great plant. It was even hardy in Alaska, and I had to get it here too.
