A purple field

Dear Diane,

As I replied to John Grimshaw, I did not know of any echiums that were this
height.  Several species growing in California are over 6 feet. I looked up
weeds in Australia just now and came across Echium plantagineum (Patterson's
curse). I don't know it but it is desceribed as an 'Erect annual herb to 60
(rarely to 150) cm high'. I'm not disagreeing with you although the plants I
saw were much lower than this. Maybe there is another, smaller species.

My first thought was Echium,  Patterson's Curse, which grows in such great
swaths in Western Australia that it can probably be seen from space.

I saw scattered plants of it in the Eastern Cape in January.  I think if it
had taken over fields there, then it would be well known to wildflower
guides, but our two guides did not seem unduly disturbed by  
it.   I warned them of what it had done in Australia.
