Yes, they seem to be those mini Mexican Cucumbers. I tried these for the first time this year, very slow to start off indeed, they are just starting to hold onto their trellis, still tiny, but the end product I saw used on a cookerey program looked like those in the photos. I am not holding my breath for a huge success.
Thanks for your insight, GKW and Simone. I found an article from Texas Parks and Wildlife that warned to only eat when green. Once they turn purple, they act ''as a laxative without warning''. Needless to say, I won't go out of y way for these.
