Zuzu, I now live in the middle of the woods of a gorgeous area named after the Lagoon in the center of the surrounding mountains and hills (Laguna de Aculeo), but the Lagoon is now just a good memory ..... except for a small muddy puddle, it is totally dry. I have lost many plants and seedlings since I live here, but then every Spring (now) I think: this was the last year of draught! Yes, water is a serious problem for us in summer, for we rely on a small puddle in what used to be a spring to supply 2 houses (1 with a plants freak and the other with a canine hotel), plus the cows and horses that are let loose to roam here - no commercial water supply available! Most part of Spring, all Summer and most of Fall are rainless. I had to add the word 'frustration' to my lexico! I sincerely hope that this years 'El Nino' brings us some extra water.
Will have to study a bit about taxonomy. Thanks!
