How beautiful Karla! I'm sure I could spend many a happy hour chatting to your Dad - I love plants and have a 'thing' for knowing the names!
Can you ask him if that dark columbine (in England the common name is also 'Granny's Bonnet') is Aquilegia vulgaris 'William Guinness'? If so, I grow it as well! I think the funky one is 'Norah Barlow'? I've got that one too! As for the irises WOW obviously his passion! The colours are stunning, but I must say I always go back to the rich blues of the sibericas. Smaller flowers and more delicate looking.
Your photography is wonderful - do you enter competitions? You should!
