Heuchera 'Blackout'

Coral bells (Heuchera 'Blackout') are perennial plants that feature luscious, deep purple foliage, accented with tall, airy clusters of whitebell-shaped flowers appearing in summer. This versatile plant grows well in both full sun and lightly shaded areas of the garden. As its name suggests, it stands out with its dark leaves, especially with the delicate white flower spikes rising above the foliage. A low maintenance groundcover with a tall, mounding habit, Heuchera 'Blackout' provides year-round interest in beds, borders, and containers.

watering

To properly care for a coral bells plant, water it regularly but do not overwater. Generally, coral bells need to be watered about once or twice a week. However, during the hotter months, you may need to water the plant a bit more frequently (around 3 times a week). To check if the plant needs water, feel the soil - it should be moist but not soggy. If the top of the soil feels dry, then it's time to water it. During the wintertime, when the plant is not actively growing, it is better to keep it in a slightly dryer condition and only water once a week.

sunlight

Coral bells (Heuchera 'Blackout') requires full sun to a few hours of daily sun for flowering and best overall performance. Generally, 5 or more hours of direct sun is best, especially during the summer months, although plants may survive with only 3 to 4 hours of daily sunlight. If your coral bells get too little sun without any supplemental light, they may not bloom and foliage may become thin and unattractive. It is important to provide these plants with enough sunlight during the spring months. If you want the plants to flower, avoid planting them in heavily shaded areas.

pruning

Coral bells (Heuchera 'Blackout') should be pruned in early spring. Pruning should be done lightly, with light trims taken from the tips of the plants and dead and damaged foliage removed. Pruning can also help to open up the coral bells, making it easier to air flow and sunlight to the shapely plants. If the coral bells are in a group, trimming them back to a specified height can create a unified look. Pruning should also be done at the end of the season in order to maintain the size and shape of the plants. In most cases, no more than 1/3 of the foliage should be removed. Pruning too much foliage can reduce flowering and foliage colour for the following year.
