Plants which will regrow from root crowns

[TWP]

This article lists eight plants which may be regrown if you preserve the crown (just above the roots).https://brightside.me/article/eight-vegetables-you-can-buy-once-and-then-grow-forever-10855/

Personally, I've never been able to get carrots to grow a nice root using this method.

This is a very good practice since it unlikely that seeds will be sold after an "event"...

It also is faster than starting from seed and can be done indoors, for instance before the ground is ready for planting.

The plants listed are:

Spring Onion
Garlic
Bok Choi
Carrots
Basil
Celery
Romain Lettuce
Coriander

Advice is given on how to get the crowns to root again.
