Light it Up!
Just like the remarkable hour of twilight when the fireflies light up the sky, the intensely yellow flowers glow bright against the dark red foliage of Nightglow™ Diervilla.
As the season fades, dark red foliage becomes more intense. It’s also easy to grow, so you’ll have more time to relax and enjoy the view.

Planting and Care
Planting your Nightglow™ Diervilla is easy:
Dig a hole twice the width of the pot, and deep enough so that when you place the plant in the hole, the top of the root ball is level with the ground around the hole. Fill in the space around the plant with a planting soil mix (you can buy this where you buy the plant) and press the area down with your foot.
Give the plant a good watering to help it settle in.
Relax!
Your plant will do well with additional water when it’s hot. But to see its fuller potential, follow these steps!
Mulch
An easy way to keep weeds down around your plant, and to keep it moist with less watering is to throw a 2 inch layer of mulch around the base of the plant – basic bagged “landscape mulch” from your local garden centre will do the trick.
Fertilize
Your Nightglow™ Diervilla won’t need a lot of fertilizer, but it will benefit from a shot of good all purpose fertilizer in the spring when the leaves start to sprout. A fertilizer with a higher middle number (e.g. 15-30-15 or 5-10-5) will work best.
Prune
Prune in very early spring into a low mounding shape, for great form and flower performance.
