A goal that I am constantly working on is finding new and different color combinations that work well in the landscape. Most recently, I’m intrigued with the use of chartreuse… that bright clean and electric green/yellow. This color seems to make the plantings vibrate with energy. I like the way it contrast with reds. I like the way it perks up pinks. I like the way it reminds me of magical places.
Here is a planting combination using 
Lime Mound Spirea, Purple Diamond Loropetalum and Blushing Knockout Rose. The Lime Mound Spirea puts the sparkle in the planting scheme.
Other plants can be used that have the same or similar vibrant chartreuse color. One of the easiest to grow is the Marguerite Potato Vine . It is an annual in Zone 7 which may be a good thing if you want to tone it down or try a different combination the following year.
Another great plant selection is the Lemon Coral Sedum. This plant hugs the ground and is chartreuse green all winter. Then in spring it burst out with tiny bright yellow flowers. The color is vibrant and carefree with a touch of whimsical. You can see in this photo how the scale of the plant is perfect for this miniature setting of a girl and her dog.
Chartreuse is a great color to perk up the landscape… I think you’ll like the sparkle it adds.
Have several pots with ‘Lemon coral’ Sedum, as well as two areas where it cassades over a block wall. Great plant!
I use it in landscape design whenever the opportunity permits.
