The garden at the end of November is still producing. Mainly they are “green” root vegetables that lack color like tomatoes or eggplant. But the output is still considerable. And includes:
- Radish (mostly black)
- Kale
- Brussels sprouts
- Kohlrabi
- Green onions
- Leeks
- Beets
- Celery
- Carrots
- Parsnip
- Celeriac
An example garden harvest in late November:
Garden Harvest End of November
I also got a bucket load of green tomatoes this month when dismantling the tomato trellis for winter.

The important thing to see here is that a garden can go a long time into late season production if one plants the correct cold tolerant plants at the correct time of the year.

No celeriac or brussel sprouts here, but I have the others plus lettuce, spinach and red cabbage. Stretching the gardening season past frosts takes some planning, but as you stated, is well worth the effort.

Also great over cold season garden vegetables. A good addendum.
I did plant winter lettuce, but due to an unexpected very warm October, it all bolted. 😦
Side note: We seem to share a common lust for lavender. 🙂
