I'm only gardening since a couple of years now, still needing to look up basic info on this or that plant that I'm growing. But often I notice that my plants behave in a way that the textbook didn't prepare me for, or sometimes the textbook seems plainly wrong.
Especially when plants show more longevity than expected or a procreation method that is new to me I'm pleasantly surprised, and I believe it's worthwhile to share here a few things I found out, because if I missed the info before, likely other people did too. Or perhaps other people know of examples that compare to the two examples I'm posting below...
Leeks which make bulbs:
This is not the leek that's called perennial leek, that's a different strain, but this leek had made a bulb resembling those on perennial leeks. I was surprised when I found this bulb on a forgotten ordinary leek - the leek had already made a seed head. I had another old leek standing in the garden, I checked and found a bulb on the foot of that one too. I've left this leek standing, and now you can see a new leek forming from the foot of the old one:
A different veg: Cavolo Nero, maybe you call it Tuscany kale, maybe Palm Kale, maybe different even, but this is how this kale commonly looks like (not my own kale):
As I like to save my seeds, I let this kale overwinter and go to flower. When I was harvesting the seeds, I already saw young leaves sprouting from the old stem of the only plant I had spared by that time. So I left it, and it has now turned into a multi-stemmed kale. While last year I hardly had a harvest from a small row of plants, as the plants had remained small and the slugs had had their takings as well, this year I'm having a decent harvest from only one plant:
This looks like a perennial, while if looking up this plant online, you'll likely see it described as a biennial.
A leek just making one bulb, and only after letting it go to seed, might not be too interesting from a practical point of view. The Palm Kale booming in size after leaving it in the garden definitely seems interesting to me.
