Genus guide
Picea — 33 species
Part of the Conifers family (Pinophyta)
Picea is a genus of roughly 35 coniferous evergreen trees grown for their conical form, stiff needles, and year-round structure. Species such as White Spruce (P. glauca), Colorado Blue Spruce (P. pungens), and Oriental Spruce (P. orientalis) demand full sun and grow best outdoors in USDA zones 2–7, with deep, well-drained soil and modest supplemental watering during dry spells — established trees are drought-tolerant once rooted. Toxicity varies by species: some Picea are listed by the ASPCA as non-toxic to cats and dogs, while others have not been fully evaluated, so confirm each species before bringing one into a pet household.

Picea — frequently asked questions
Are Picea plants toxic to cats and dogs?
Most Picea are not pet-safe. Of the 33 Picea species in the Growli library, 17 (52%) carry a toxic or mildly-toxic ASPCA classification and 16 are pet-safe. Always confirm the exact species on its pet-safety page before trusting it around cats or dogs.
How much light do Picea plants need?
Most Picea do best in direct sun. If yours stretches toward the window or loses its variegation it wants more light; scorched or bleached leaves mean it is getting too much direct sun.
Are Picea easy to care for?
Some Picea suit more experienced growers — several want strong light, sharp drainage or a specific seasonal rhythm. Check the individual species page for the exact regime.
How many Picea varieties are there?
