Anyone who's paying attention has seen the collective size of garden plants shrink over the past couple decades. The official rationale is that gardens are getting smaller, so plants need to be smaller as well, but that's pure malarkey. Smaller plants fit on shorter shelves, meaning more per cart, more per truck and so on. Trucking efficiency has changed our horticultural availability and I don't like it.
I'm happy to see some breeders are breeding in all size categories once more. No, Heucheras were never Gunnera-sized, but they used to be bigger! I enjoy them in the garden, but I also love cutting the foliage and flowers. The flowers are a bit too dainty for my tastes, but the foliage is long lasting and can come in a wide range of designer colors and patterns. We may have to wait a bit longer to get tall Heucheras in all the colors, but we can get ready with 'Mahogany Monster.' Its light mahogany changes from rusty red to burgundy throughout the season making it the perfect companion for blues, grays and greens, or even pinks, reds and oranges. All propagation prohibited.
