Gurcharan ji, I think the 2nd picture is U. californica. Other two pictures are correctly identified. As you might know, U. californica is native to California, Oregon etc. whereas, L. nobilis is a Mediterranean species and occurs only under cultivation in the USA.
Aarti ji, I really appreciate your identification of this (and several other) species and also your keen observations. These plants can confuse even trained experts. Great work! In our paper <http://pubs.acs.org/doi/abs/10.1021/jf4052682>, we have compared both the species by their chemistry and leaf anatomy.
