Gentiana 'Big Blue' - Gentiana with large, deep blue flowers

Gentiana 'Big Blue' is a compact and spectacular perennial, valued for its large, trumpet-shaped flowers in a deep, almost electric blue. The flowers rise above the dark green foliage and create a striking contrast, making them ideal for pots, planters, borders, and alpine gardens.

The plant forms a low, dense clump with narrow, lanceolate leaves, while the buds are decorative even before opening. It is an excellent choice for gardens where a hardy perennial with a rare and intensely vibrant color is desired.

❄️ Cold hardiness and growing in the garden

Gentiana 'Big Blue' is suitable for permanent cultivation in the garden and tolerates low temperatures well. Under suitable growing conditions, it can withstand temperatures down to approximately -24/-25°C.

During winter, the above-ground part may become less decorative, die back, or partially dry out. This is normal for a perennial plant entering dormancy. In spring, as temperatures rise, the plant resumes growth from the base.

For successful overwintering, it is important that the soil be well-drained. Gentiana tolerates cold better than excess moisture accumulating around its roots.

🌱 Secret Garden substrate recommendation

👉 We recommend an airy, well-drained substrate rich in organic matter that retains sufficient moisture without becoming waterlogged.

For planting in the garden, heavy soils can be improved by adding materials that increase drainage and aeration.

📌 Note

Gentiana is a perennial plant, and its appearance naturally varies depending on the season. After flowering, the flowers fade, and the foliage may become less decorative as the plant enters dormancy.

Plants may be delivered with open flowers, buds, spent flowers, or no flowers, depending on the time of dispatch. The number of flowers and flowering stage cannot be guaranteed.

During the autumn-winter season, the above-ground part may be reduced, yellowed, or partially dried. This is normal for the plant's seasonal cycle and does not indicate a viability problem. In spring, the plant resumes growth.
