Blooming Time

Early Bloom (E)

  • Timing: Typically begins in mid to late April (depending on zone)

  • Notes: These irises are among the first to bloom in the spring garden and help kick off the season.

  • Examples: Many Standard Dwarf Bearded (SDB) and Miniature Tall Bearded (MTB) irises bloom early.

Early-Mid Bloom (EM)

  • Timing: Follows shortly after early bloomers, often in late April to early May

  • Notes: Transitional bloomers that bridge the gap between early and mid-season irises.

  • Examples: Some early TBs (Tall Beardeds), intermediates, and additional dwarfs.

Mid Bloom (M)

  • Timing: Typically peaks in mid to late May

  • Notes: The core bloom season — most Tall Bearded (TB) irises bloom at this time.

  • Examples: The bulk of hybrid and historical Tall Bearded varieties.

Mid-Late Bloom (ML)

  • Timing: Late May into early June

  • Notes: These irises extend the season, blooming after the peak but before late bloomers.

  • Examples: Some late TBs and border bearded types.

Late Bloom (L)

  • Timing: Early to mid-June

  • Notes: The final group of spring-blooming irises. Helpful for stretching the visual impact of your iris beds.

  • Examples: Late-flowering TBs, some historics.

🌿 Rebloom (Re)

  • Timing: Late summer to early fall, often August through October

  • Notes: Reblooming irises flower again after their initial spring bloom, depending on zone, weather, and care. Not all rebloomers rebloom every year or in all climates.

  • Examples: Known reblooming cultivars like ‘Immortality’ or ‘Autumn Circus’.

🗓️ Zone Notes for ACF (Zone 7b)

  • Our Peak season typically runs late April through early June
