'Summer of Love' Rose Color Variation: Climate Sensitivity Explained

45 years of rose growing and you've never seen this? 'Summer of Love' is uniquely climate-sensitive—its color expression shifts dramatically with heat and humidity.

The Evidence

HelpMeFind.com photos reveal the range:

• California (hot, dry): Rich, saturated colors as cataloged
• Texas (hot, humid): Pale, washed-out tones until autumn

Why This Happens

Anthocyanin pigments (reds/pinks) degrade in high humidity + heat. The rose isn't "wrong"—it's responding to your microclimate. First-year plants often show muted color as roots establish.

What to Expect

• Spring/fall blooms: Truer to catalog color
• Summer peaks: Diluted, cream-dominant
• Year 2+: Often deeper color as plant matures

Your Theory: "Dilute Color Gene"

Unlikely. This is environmental expression, not genetic instability. The same bush in a different climate would perform differently.

Patience. This grandiflora needs time to acclimate. Many roses (like 'Love') disappoint year one, then dazzle year two. Your experience is the anomaly—not the rose.
