Spirea
Spiraea japonica / × vanhouttei
Family Rosaceae
Spirea is the shrub that never sends a bill: foam-white or raspberry-pink flower clusters twice a year, tidy mounds from two to eight feet, and a constitution that laughs at drought, cold, and neglect. Its parking-lot reputation only proves how unkillable it is.
When it blooms, it hums — butterflies and bees blanket the flowers — and it's safe around pets and kids. Massed along a foundation or run as a no-skill hedge, it simply performs, year after year. If a spot needs reliable color with zero fuss, this fills it.

What each band means
- Bloom — flowers open — pollinators working, frost on blossoms is the danger.
- Prune — shape it now — cuts heal cleanly and structure is visible.
These are the species' typical months — expect them a few weeks earlier in warm zones and later in cold ones. Watch the plant, not just the calendar.

Questions
Spirea questions, answered straight.
Is spirea safe for kids and pets?
Spirea is commonly eaten and isn't considered toxic, but "commonly eaten" isn't a guarantee for any particular person or animal — allergies, quantity, and which part you eat all matter. Never eat a plant you haven't positively identified, and check with a vet before letting pets or livestock graze anything new.
How do you propagate spirea?
Seed (stratify), cuttings, or layering.
