Primo® 'Mahogany Monster' Coral Bells (Heuchera hybrid)

Our perennials are currently going dormant. The foliage and blooms begin to brown and die back. We provide a hard trim in the greenhouse to support this process. During dormancy, plants go inactive to conserve their energy for the next growing season. This happens naturally as seasons change!

Our perennial plants are entering their natural dormancy phase. As part of this process, foliage and blooms are browning and dying back—this is completely normal! We give the plants a hard trim in our greenhouse to support them as they conserve energy for the next growing season. Rest assured, your perennials will wake up and thrive again when it's time in your growing zone. Dormancy is how they prepare for a healthy, vibrant comeback as the seasons change!

Care: Trim back tattered foliage in early spring. Fertilize with Proven Winners Continuous Release Plant Food in spring.

Full, good looking plants. Plants came very well packaged and very little dirt at bottom of boxes, even though delivery driver placed them on their side on my porch. It clearly stated “This Side Up” on the box.

Spectacular color

Proven Winners Mahogany Monster was delivered in excellent condition except for several broken stems from a crushed box. Plaed these into a bud vase for continued indoor enjoyment. Hope they fare well in our hot Texas Summer next year. We shall see. Heuchera are awesome year round enjoyment. Just need durable hybrids for our hot climate.
