Purple Clematis viticella Seeds – Italian Leather Flower Vine – Hardy Zone 4 Perennial Climbing Vine – Trellis Garden Plant

Purple Clematis viticella Seeds (Clematis viticella)

Purple Clematis viticella, often called the Italian Leather Flower, is a graceful, long-blooming climbing vine prized for its rich purple blossoms, vigorous growth, and exceptional cold hardiness. This classic cottage-garden favorite produces masses of nodding flowers that cover trellises, fences, arbors, and pergolas with color throughout summer.

Unlike many large-flowered clematis, viticella types are tough, disease-resistant, and easy to grow, making them ideal for both beginners and experienced gardeners. Their twining stems quickly climb supports, creating a soft, romantic vertical display in the landscape.

Native to southern Europe, this hardy perennial thrives in a wide range of climates and returns reliably each year, growing fuller and more floriferous with age.

Clematis Germination:

1) Fill Gardening treys with a well draining seeds starting mix. Be sure they are at least 3" deep as Clematis have long tap roots once the start growing. Wet the soil to keep it damp. Not wet as it will rot the seeds.

2) Lightly press the seeds into the soil, but do not bury. Cover with a very thin layer of sand as they "need light to germinate", and use a spray bottle to mist and keep moist when needed. They cannot dry out or the seed will die, and they cannot be wet because it will rot the seeds. Just "moist" at all times.

3) To cold stratify, seal the pots or planting treys in a plastic bag and place in the fridge for 90 days to cold stratify them. Periodically check to be sure they are not drying out.

4) Remove the seeds from the fridge and place them in bright light, not direct sunlight at first. A grow lamp or window seal will work great, but keep the soil temperature above 70 degrees F at all times.

5) Expect germination in 6-8 weeks.

Germinación de la clemátide azul:

1) Llene las bandejas de jardinería con una mezcla inicial de semillas con buen drenaje. Asegúrate de que tengan al menos 3" de profundidad, ya que las clemátides tienen raíces pivotantes largas una vez que comienzan a crecer. Humedece la tierra para mantenerla húmeda. No mojes la tierra porque pudrirá las semillas.

2) Presiona ligeramente las semillas en la tierra, pero no las entierres. Cúbrelas con una capa muy fina de arena, ya que "necesitan luz para germinar", y usa un rociador para rociar y mantener húmedas cuando sea necesario. No se pueden secar o la semilla morirá, y no se pueden mojar porque pudrirá las semillas. Solo "húmedas" en todo momento.

3) Para estratificar en frío, sella las macetas o bandejas de plantación en una bolsa de plástico y colócalas en el refrigerador durante 90 días para estratificarlas en frío. Controla periódicamente para asegurarte de que no se estén secando.

4) Saca las semillas del refrigerador y colócalas en un lugar con luz brillante, no bajo la luz solar directa al principio. Una lámpara de cultivo o un sello de ventana funcionarán muy bien, pero mantén la temperatura del suelo por encima de los 70 grados F en todo momento.

5) Espera la germinación en 6 a 8 semanas.
