Awesome heuchera for me! It does very well here. Never dies over winter. Looks lush and full all summer. This one seems to turn a pumpkin orange around the edges in fall.

Great heuchera overall. Hardy, full and lush, and nonstop beautiful foilage.

I loves Dale's Strain! It currently rank in the top 10 heuchera varieties for me. It does very well for me, with very low death rate - some heuchera cultivars are wimpy and other thrive very well with me. It have variegated white on its leaves - flowers is not valuable but can be removed - the leaves is the main interest - does well in partial shade with a bit of direct sun.

I've never been much interested in heucheras but I got this little and cheap at a local garden shop, liking the foliage. It's burgeoned into a 10" tall by 12" round plant in a container on my shady porch. Didn't bloom there, but Dale's strain doesn't have showy flowers anyway. The foliage really is pretty - not as showy as some heucheras you'll see, but subtle and lovely. I'm planning to divide it for use as a ground cover in a semi-shady area of the yard that's crowded with daffodils in spring, but bare (or weedy) the rest of the year.
