Blue Siberia larkspur (Delphinum grandiflorum) is an unusually elegant and impressive perennial plant. It forms beautiful, eye-catching spiked inflorescences that consist of large numbers of tiny flowers. Intensely blue blooms develop continuously for weeks, from late spring until end of summer. This larkspur grows circa 50 cm tall and does not need supports. These unusual plants will introduce sky-blue colour, rather rare among flowers, into your garden. Larkspur fits perfectly into elevated perennial beds. We advise to plant it together with pink and white blooming plants, along fences or walls. It is also fitted for cut flowers, as it retains freshness in vases for up to two weeks.

Larkspur seeds sold in our online store are sown indoors or in garden in spring. Young plants will withstand spring colds. Germination in temperatures around 15°C takes approximatey 2 - 3 weeks. Larkspur grows best in clay-sandy, moist, permeable soils that are rich in nutrients. It will bloom abundantly forming impressive inflorescences on sunny sites.

Where do our seeds come from?

All of the seeds sold in our shop come from the best producers from across the European Union. Thanks to a long-standing cooperation with them we were able to develop the most adequate storing and dispatch conditions, guaranteeing that you always receive fresh and carefully tested batches of seeds. Exclusion of the middlemen from the whole process not only makes it possible for us to avoid sending out-of-date seeds that might have been lying too long on a warehouse shelf, but also ensures the most attractive price for top quality products.

The quality control process

All our seeds must pass a four-stage quality control process.

Stage one begins with a careful selection of the suppliers. Than we proceed with controlling their crops, foreign producers are not excluded from the quality control process. Plants are checked at every stage of their development: when they start to grow, during blooming and when they start bearing fruit (seeds). At this stage the most important thing is to ensure proper spacing of the plants. Thanks to that obtaining the desired morphological characteristics of each particular species or variety, such as colour, height and shape, can be ensured.

Stage two consists of a detailed verification tests in laboratory conditions. With the use of the highest quality equipment by the highly qualified staff, our suppliers perform more than 30 000 quality checks annually. The seeds that do not meet our requirements are subject to technological refining processes, including drying, cleaning, upgrading and testing again.

Stage three starts with sowing seeds in selected control plots. That way we obtain valuable, exact information concerning their germination that must be maintained at an appropriate level. Simultaneously, the varietal identity of each species is checked at this stage.

Stage four takes place in our warehouses and consists of eliminating seeds that have been stored for too long on our shelves and replacing them with new batches. Each package is stamped with a unique batch number and also with the sow-by-date.

All four stages combined allow us to state with confidence that the seeds we deliver comply with the highest standards and have completed all required control stages with flying colours.
