Heuchera 'Toffee Tart is a new introduction from Proven Winners. Just like its name, 'Toffee Tart' displays differing shades of ginger caramel throughout the seasons. In spring, newest leaves are amber with a silver overlay. Mature leaves are ginger color with silver overlay. In late summer, leaves mature to green. Since it's a lighter leaf color, it should have some shade protection (do not plant in full sun). Creamy white flowers are held on burgundy stems. It is perfect for brightening up landscapes or serving as a filler in combination containers.

Growing and Maintenance Tips
Heucheras are easy to grow and fit nicely in the front of any border, rock garden, or container. They grow most vigorously and have the most intense colours when grown in partial shade (preferably afternoon shade). They can also be grown in more shade but their growth rate will be very slow. The soil should be amended with organic matter prior to planting. It should also have good drainage and a neutral pH. If properly sited out of the way of winter winds and with reliable snow cover, Heucheras may be evergreen. If the plant looks tattered by early spring, shear off any damaged leaves to make room for the vibrant new foliage which will fill in quickly.
Heucheras can be grown under Black Walnut trees because they are resistant to the toxin Juglone which the trees emit from their roots. Heucheras are also salt tolerant. They are useful in the north along pathways which are salted. Occasionally in northern regions, Heucheras have a tendency to heave out of the ground because of the freeze/thaw cycle. To combat heaving, add an extra layer of compost around the plant's roots in the fall. In the spring, if the plants have heaved at all, the new roots will grow into the fresh new layer of compost.
