I've been adding to my collection of perennial vegetables as I learn about more of them. There are photos below of some of the ones that haven't been covered in my previous photo roundups. (Photos here from 2013/4 and 2014/5).
Some of the plants shown below are still too immature to harvest so I haven't tasted them yet but will blog about them when I eventually do! I've given them their common names but you can find specific names at the bottom of the page.
There is a photo of a plant I bought as "giant chives" amongst the 2013/4 photos. Although this is a robust plant it only grows to about 35cm, not much taller than my other chives. I don't have a record of its Latin name so to be surer of what I am growing (and potentially selling) I bought another (or possible the same!) plant sometimes known as giant chives, Allium ledebourianum, from the German nursery Deaflora (photo below). The notes in the nursery catalogue estimate its mature height at 70cm (probably the height of the flower stalks) although other sources give lesser heights. So I'll be interested to see if this one proves to be a true giant.
