Only a few of these were blooming (literally 10 out of 100,000 plants I saw) - I think it was because they were alongside a road with some construction going on - probably resulting in a bit of water spraying and runoff which kicked these into flowering mode?
Really cool to look at BUT ABSOLUTELY A PAIN to get pricked by of of these! It was really hard and painful to remove.
