The desert thistle (Blepharis pruinosa) can grow up to 1m high. Its long spikes allows it the luxury to remain protected from predators. Even the flowers, densely clustered mainly in fours, are armed with extremely spiny bracts. Blepharis pruinosa bear pretty blue flowers which become cream-coloured to white once dry.
