Spirea ‘Neon Flash’ (USDA Zones 4-9) is a Bright! Magenta! Pink! flowering shrub to about 4’ tall, which loves full sun and blooms off and on throughout the summer. It does lose its leaves in winter and gets a bit of reddish-yellow fall color, but the fall color isn’t anything to rave about.
I love the fine texture of the leaves, the neat, compact habit, and the Bright! Pink! flowers. This is an easy Spirea to care for so long as it has reasonably good drainage, an application of organic fertilizer in spring and regular water. It can sometimes get a bit of powdery mildew around the blooms if it is unhappy, but overall it is a sturdy, easy-care plant that gives a lot more back than it asks from us.
I make sure to deadhead it promptly to encourage rebloom, and sometimes I’ll get three blooms in one season from it – a good six months of color. If you’re keeping up with things often, just prune out the individual flowerheads as they go brown and leave the new buds to bloom. If you’re a more casual gardener, just wait until the whole thing is done blooming, then cut the entire flowering stem down into the rest of the foliage so you don’t notice the cut stems. It will rebloom for you soon!
Deer-resistant but not 100% deer-proof, I love this Spirea with Hebes, Salvia leucantha/ Mexican Bush Sage, ornamental grasses, and that wild tropical-looking Alstroemeria ‘Third Harmonic’ shown in the photo.
