Typical bloom times for much of the US. Flowers bloom earlier in warm regions and later in cold ones, and weather shifts timing from year to year. Some annuals pause in high summer heat. Many garden flowers, including lilies, daffodils and tulips, are toxic to pets; check before planting or bringing flowers indoors.

Summer
