Sylvetta Perennial Ar...
Same flavor as annual arugula
with deeply-cut leaves to 6".
Overwinters to zone 6. Compared to annual arugula, it makes a thick bed of smaller, spicy leaves through spring, summer and fall.
Yellow flowers that bees can't resist. We have never seen so many bees on anything! Makes a thick drought-resistant bed that produces all year. Also does very well in pots. Self-sows like crazy in warm climates, so keep it in a small bed or container of its own.
BOTANICAL NAME: Diplotaxis ericoides
GROWING INSTRUCTIONS: Germination is staggered over time and the seedlings have long taproots, so plant in a deep pot or flat. Prepare a permanent bed in the garden, as for any perennial. If you live in a very cold area (zones 2-4), grow as an annual. Good understory around taller plants. Start harvesting outer leaves once there are more than 6. Flowers are edible and draw beneficial insects. For maximum leaf production, you can shear off the flowering stems as they develop, or just let the plants flower and have a bed for constant but smaller production.
GROW BIOINTENSIVE® CULTURAL INFORMATION: P/Zones 5-9/Spacing 8-12"
ADDITIONAL INFORMATION : Sylvetta is perennial, and it's deep taproot makes it heat as well as cold-resistant. It is slower-growing but produces both leaves and flowers all summer, and overwinters to zone 5 if given mulch or row covers.
