Important notes

flowering / 2nd year: In its 2nd year parsley bolts and flowers — leaves turn bitter and apiole rises; avoid large amounts in pregnancy.

sap on skin + sun: Contains furanocoumarins; sap on skin may irritate in sunlight.

Luce

Bright to part shade, 12–14 h of light. Tolerates less sun than Mediterranean herbs.

Irrigazione

Keep evenly moist; drought turns it bitter and triggers bolting.

Temperatura

Prefers cool: 15–22 °C. Heat triggers premature flowering.

Umidità

50–65 %.
