Amazing what a difference a bit of rain makes. In previous years one corner of the allotment has been carpeted by Nasturtiums. [for example see entry dated 27th. October 2021}

 They self-seed copiously and being a fast growing annual reappear early the following summer lasting well into autumn. That didn't happen this year- up till now. Nasturtiums flourish in arid soils and are well suited to drought and heat. Even so they do need some moisture to germinate and there wasn't any for months. The recent rainfall has instantly activated them.

 They won't survive the first frost but assuming we have a reasonably warm autumn they might yet run rampant. As I've noted before the leaves and flowers of Nasturtiums are edible and the seeds too when they are still soft and green. Here on the allotment I think they can be considered a cover crop and green manure as they are (usually) so prolific.
