I notice that a lot of people hit my blog by searching “artichoke” and “square foot gardening.” Check out my entry about growing artichokes:(https://themidnightgardener.wordpress.com/2010/08/29/artichoke/)
In the meantime, while driving through LA today, I noticed a neighbor with artichoke plants, so I snapped a photo to describe why I plant these as perennial landscaping and not in my square foot garden beds. As you can see from the plants below, they are larger than the car!
If you don’t know what you’re looking for, the artichoke is just above the comma in this sentence. It is in front of the window. As you can see, while it is several plants, they are cumulatively taller than the car and much wider than the car! While too large for a square foot gardening bed (unless you’re going to use a 4×4 and let them have the whole thing – and what would the point be?) they do make terrific landscaping plants!
