Gardeners' Notes:

I love this plant but rating neutral for now as new in my garden. Planted in amended soil, bright shade.


On May 17, 2016, Eldine from Wellsville, NY (Zone 4b) wrote:

I love the different shades of tan on this heuchera. Every leaf is a different color. I do have to say that it took YEARS before this plant got to its proper size. For some reason, it was very tiny, barely making it, for at least 3 years. I ignored it and finally this year it looks great! It's a wonderful color contrast to red leaved heucheras, lime/yellow heucheras, and lady's mantle (which has a bluish hue.). I'm in zone 4b and I have it facing east (morning sun, no afternoon sun.)


On Apr 7, 2015, coriaceous from ROSLINDALE, MA wrote:

This is a hybrid of the southeastern native H. villosa, which brings greater tolerance of heat and humidity. Brighter leaf color and better performance than 'Amber Waves'.

In the 2012-2014 Mt. Cuba Center foliage Heuchera performance evaluations, it was listed as one of the top 10 (out of 83).

Discovered by Sandrine Delabroye.

Tough yet beautiful heuchera variety. Leave it elbow room as it does spread.

has grown very well and quite large in zone 5..after 3 yrs I was easily able to divide it in 3 - this summer one was planted in a container - very nice, will go back in ground before winter - part of a collection of about 20 different H. cultivars in part sun/part shade bed under borch and oak.

I love this plant's color, it adds such interest to the front of my beds. However, beware- it is not as sun tolerant as its tags may suggest. It is doing fine in a part-shade garden, but is crisping in my south facing bed and will have to be moved.


On Mar 12, 2010, HoosierGreen from Danville, IN wrote:

For two years, this cultivar has performed beautifully for me. It's become my favorite for a real splash of color. Does equally well in exposures from just morning sun to mostly sun, but avoiding late afternoon hot sun.
I love the range of color shades on one plant which blend with most everything in the garden. Mostly evergreen, but I usually cut it all back in early spring to let it grow a fresh set of leaves. (It is a far better and studier plant than the similar 'Amber Waves' which melted in summer heat.)


On Jul 6, 2009, fel from Wynnewood, PA (Zone 7a) wrote:

I love the color in the picts, but for me this heuchera is hard to please. First it was in too much shade and it didn't grow at all. Then last fall I transplanted it to partial sun. At first it liked that -- it grew a bit and turned bright yellow, but now (in July) it is filled with holes and looks raggedy. So I moved it again, back to a shadier spot. My other heucheras are much less picky.

The parent plant of this variety is nothing other than the same species that made 'Palace Purple' Heuchera.

Hybridizer: Thierry Delabroye, France. Introduced in 2006. H. 'Caramel' was officially launched at Courson (the largest plant exhibition in France) in October 2004.

Non-invasive and not at all demanding, this little beauty was my first Heuchera. It has lovely orangy-golden colored leaves, with a darker underside. I have it growing as ground cover near my giant hosta, and it has done nicely in my mostly shady clay soil. I would estimate that in summer it gets 2-4 hours of direct sun. I don't remember its flowers, it may not have flowered at all (I've had it for about 7 months). I understand that this plant is an evergreen (or in this case, evergold), so far it has held up to light frost.
