An eastern exposure is typically not considered a "full sun" situation. It is more usually considered one that receives morning sun and then afternoon shade, as the sun passes over the house and begins its western descent. Of course, if you plant well away from any shadow the house may cast, that may increase the amount of direct sunlight the plant may receive.

Given these conditions, nearly any heuchera will be happy. Provided soil conditions are good (a rich, organic and moisture retentive soil), any red or dark leaved heuchera is perfectly happy sited here or even in full day sun, as are those with green leaves. If the area gets lots of afternoon sun, the yellow or gold/lime colored heuchs might be challenged - they prefer some shaded protection from the intensity and heat of afternoon sun (as do most gold leaved plants).

Thanks. I am looking at The Golden Zebra. I will see how much sun they will actually get. They are too expensive to lose by planting them in the wrong place. The will be planted about 20ft. from the house.

Golden Zebra is actually a heucherella rather than a heuchera and heucherellas all prefer at least partial shade. And because it is a gold leafed variety, it is not at all happy in strong sunlight. I would place where it was protected from afternoon sun.

What verity do you suggest.Since i like the color of orange which one would be best? I would choose red but they are being planted next to Nandinas.

I'd look at 'Georgia Peach' or 'Peach Flambe'. Both will hold up well in a lot of sun, provided watering is adequate. Also 'Ginger Peach', 'Paprika' or 'Marmalade'. And I wouldn't necessarily discount the reds - most are very coppery in color rather than a true red and suit the coloring of nandina beautifully so I'd also consider 'Fire Chief' 'Root Beer', 'Mahogany' and 'Berry Soda'.

I had a Golden Zebra in an eastern exposure. It never did well and eventually died.

You tried Autumn Bride? It's not as showy as some heuchera, it has fuzzy light green leaves. It blooms small white flowers in late summer here. It is my experience that plants that bloom later in the season always look better than the early bloomers. Mine are in about 6 hours of sun at the base of a maple tree and get no extra water. They look great all season.

That's a nice healthy plant Sherrygirl!

My Carnival Watermelon and Blackberry Ice are in the sun from about 2 p.m. till sunset. They are on a slight east-facing slope so the sun isn't really directly overhead. They do fine here in zone 5B. Taken in May 2015.

I like your blackberry ice!

Thank you, serendipity. He's a happy little fellow, really really purple early in the season.

The following have been doing great for me for the last few years. They are in full sun:

Caramel (my all time favorite. grows big and symmetrical. very striking color, orange)

Obsidian (stays dark through the 3 seasons, not bothered by full sun at all)

Frost Violet (this one is tall)

Georgia Peach (blooms like crazy for a long time)

Frost (small one up to 6-8 inch, but super cute, the spring color is really beautiful)

Cajun Fire

Most of them are purple to orange colors.

I have "Galaxy" on the south side of the house - full sun and reflected from limestone. The nursery descriptions state that it should be protected from afternoon sun to prevent leaf scorch (I read this after I planted them, and the edges of the leaves do scorch.) I'm OK to replace them with more sun tolerant coral bells or something else. Any ideas? My criteria are: same size (or bit larger) as coral bells, hot blazing sun tolerant, well drained dry soil. I have considered Caryopteris (Bluebeard) but would love to hear your opinions.
