SEASONAL REFERENCE

What Should This Plant Look Like Now?

September Central Maryland

CURRENT STAGE

Late Bloom / Frost Preparation

Typical stage for September in Central Maryland

Flowering may continue in warmth, but growth slows as nights cool and the plant remains fully leafy.

Normal Right Now

  • Reduced bloom is normal; full leaf loss is not the expected seasonal pattern.

  • Leaves should stay gray-green until cold injury, which is a signal to move the pot.

  • The exact pace for french lavender can shift with sun, planting age, pruning, and Bowie-area weather.

Something Looks Different?Signs that may be worth investigating

Worth Checking

  • Blackened or water-soaked crown tissue
  • Sudden collapse following cold exposure
  • Persistent yellowing in wet potting mix
  • Fine webbing or heavy whitefly activity indoors

These signs may be worth investigating. A symptom or photo alone cannot identify the cause.

WHAT SHOULD YOU DO NOW?

Move the container to frost-free protection before Bowie’s first hard frost.

This is what a healthy plant typically looks like at this stage. It is seasonal reference guidance—not a visual diagnosis. Microclimate, weather, plant age, recent transplanting, pruning, and cultivar variation can change appearance.

Before you choose it

It is generally less cold-hardy than English lavender and should not be assumed to overwinter outdoors here.

Bowie conditions are the baseline

Container size, microclimate, cultivar, tunnel temperature, and actual weather can move the timing. Use the plant tag and direct observation with this guide.
