Arugula in Zone 11a & 11b
Eruca sativa
Yes, arugula grows in zones 11a and 11b. Plant it outside in Oct–Mar. For a fall crop, plant out in Oct–Mar.
When to plant arugula in zone 11b
Zones 11a and 11b share the same average frost dates, so this page covers both.
Method: Direct sow: Direct-sow outside. It doesn't transplant well, or doesn't need the extra time indoors.
| Window | Fall window |
|---|---|
| Start indoors | Not typically started indoors |
| Direct sow / transplant outside | Oct–Mar |
| Estimated harvest | ~40 days after direct-sowing |
Spacing: 9 per square foot (square-foot-gardening spacing). Mature height: 0.5-1.5 ft.
Zone 11b dates sourced from edis.ifas.ufl.edu.
Fall window: the last sowing date is the average first frost minus days to maturity, the method in Purdue Extension's fall garden guide, which lists arugula for late-summer planting.
Plant alongside it in zone 11b
These go outside within two weeks of arugula in zone 11b, so one planting day can cover them.
- KohlrabiOct–Feb
Arugula is about as fast as salad greens get, direct-sown and ready to harvest in around 40 days, with a peppery bite that gets sharper as the weather warms.
How arugula fits zone 11's season
Zone 11b is frost-free, so frost is not what limits the calendar here. What you can plant, and when, comes down to summer heat and daylength instead.

Zone 11b is highlighted. Useful for comparing against a neighbouring zone, or for a garden somewhere else.

Harvest dates are about 40 days after the sow or plant-out date.
Zone 2 sows before zone 3 here, which looks wrong and is not. USDA zones rank winter cold, not season length, and zone 2 is mostly interior Alaska, where hard winters come with warm summers. More on what a zone measures.
Good companions
- Carrot: Fast-maturing, non-competing salad-garden interplant. (usually zones 2-10, so not a pairing for zone 11b)
- Lettuce: Similar light/water needs; grown together as cut-and-come-again greens. (usually zones 2-10, so not a pairing for zone 11b)
Where to buy arugula seeds
Botanical Interests · True Leaf Market · Burpee · High Mowing Organic Seeds (each supplier's arugula seeds)
Varieties we recommend, and where to get them:
- Sylvetta: Cornell's Vegetable Varieties for Gardeners database describes Sylvetta (a different, wild species) as small-leaved, slow-growing, and slow to bolt, a good option if standard arugula bolts on you too fast in a warm spring. Buy: High Mowing Organic Seeds Full notes
- Astro: A wider, less-lobed leaf than standard arugula with a milder flavor while young and cool, slower to bolt, and heat tolerant once it does warm up. Buy: Botanical Interests · True Leaf Market · High Mowing Organic Seeds Full notes
- Roquette: The standard, fast-growing salad type most seed racks sell as plain 'arugula', with dark green, wide, tongue-shaped leaves. Buy: True Leaf Market Full notes
