Sylvetta

Diplotaxis tenuifolia

Although slow to grow at first, once established this strong flavoured arugula will overwinter as well as reseed itself. Leases are longer and more denticulated than garden varieties. Germination rate can be low (around 40%) but may germinate better in cooler conditions. Small yellow flowers bloom over a long period and make a spicy addition to salads.

A note about germination rates for wild seeds

Our wild seeds are not germination tested, as both germination rates and time to germination can vary significantly compared to commercial seed varieties. Many wild seeds require specific pre-treatments—such as cold stratification, exposure to light, or temperature fluctuations—to successfully germinate.

Additionally, many wild perennial plants may take several years to mature and begin flowering. 

For best results, please refer to our Growing Tips for strategies to support successful germination.

Tips for planting out wild seeds:

1. Sow your seed in the Fall, as Nature would. If you don’t want to be patient, then putting your seeds in some damp soil in the fridge for 4-6 weeks can also help germination as they benefit from a cold period.
   
2. While there are technical tips that can be followed for each wild species, we find generally good success by sowing seeds in a pot of sterilized potting soil in early Fall, and sinking the pot or tray into the ground in your garden where it can stay for 1-3 years.
   
3. Cover your seeding tray/pot with a fine wire mesh to keep out mice, squirrels, rabbits, cats and other critters who may want to nibble seedlings or dig up the nice potting soil.
   
4. When seedlings emerge in the Spring, prick them gently out with a fork once they have two sets of leaves (this indicates good root development so they survive transplanting better), then transplant them to their final location and water in well.
   
5. Leave the pot in place, and over the next couple of years it’s easy to continue pricking out new seedlings to transplant as they emerge.
