Valeriana officinalis, commonly called valerian or garden heliotrope, is a perennial flowering plant native to Europe and western Asia, grown primarily for its medicinally valuable roots used for centuries as a natural sedative and anxiolytic. Seeds are light-dependent germinators that benefit from cold stratification and prefer cool, moist conditions, typically sprouting within 7-21 days when conditions are optimal.
Before sowing
Cold stratification for 2-4 weeks improves germination. Can be done indoors in refrigerator or by autumn/winter outdoor sowing for natural overwintering.

What to expect
Tips
Seeds require light to germinate—press or tamp firmly into soil without covering. Maintain consistent moisture during germination. Cold stratify by refrigerating seeds for 2-4 weeks or sowing outdoors in fall for natural winter stratification. For indoor starting, use soil temperature of 60-70°F (15-21°C). Surface sow seeds; do not bury. Use fresh seeds less than one year old for best results. Keep seedlings moist until established. Transplant outdoors after last frost, spacing 18-24 inches apart.
