katiem2, Thank you for liking my blue selection! One of my favorite gardens is the courtyard to the Isabella Stewart Gardner Museum in Boston, particularly during their blue-themed months for spring and summer.
I love both blue and hummingbirds so this is a gold mine for me. thanks for the headsup on three blue flowers I will be planting this spring, very soon.
Mira, Yes, 'Oiseau Bleu' ('Blue Bird') is a cultivar of Hibiscus syriacus. Apparently the scientific name didn't save when I published this article. Thank you for your sharp eyes and relevant questions: I've re-inserted the details into the title of the capsule; hopefully they will save.
I hope that you are successful in locating blue columbine: it's a wonderful flower.
My wild columbines are blooming now. Their jeweled coloring of red and yellow is simply beautiful.
I came back to this article to look at the flowers. The blue columbine is wonderful. I will try to see if I can find it in flower shops but I doubt it. When you wrote "blue bird" by that image of hibiscus flowers, you meant to say the flower is also known as a "blue bird"??
Maritravel, Hummingbirds are such happy visitors to gardens that it's amazing that they aren't global. Although bees and butterflies are beautiful, the effect is not the same as hummingbirds with their fast hovering skills.
Providing gardens to attract these nectar-lovers is an important contribution to their continued success on this planet.
Just worked my way through your 'colours' articles and have learned a lot about their attractiveness to birdlife. Unfortunately, we don't have hummingbirds in the UK: my main task this summer has been to plant enough blue, mauve and purple plants to attract bees and butterflies, both of which we are losing at a dreadful rate due to pesticides and herbicides. Not many bees yet but I'm encouraged by the number of butterflies.
VioletteRose, Blue columbines are so photogenic, so it's lovely that you were able to take a photo of 2 blue columbines.
Yes, it is good that blue flowers can attract hummingbirds. Red flowers can be quite stunning, but they don't hold the monopoly on beauty, so it's nice to know that hummingbirds find satisfaction in colors other than red.
I love the blue columbine flowers, they are so lovely. I have seen them only one or two times, but I have got a nice photograph of two blue columbine flowers. I didn't know about the other two flowers, they all look beautiful. Good to know that these can attract the beautiful humming birds :)
Mira, The wind-sown plants, including trees, which have appeared as if by magic in my yard are beautiful gifts from nature, and I cherish that their windy journeys touched down in my yard.
Hummingbirds are such delights to watch.
Please let me know if Bucharest's Botanical Gardens include columbines or catmint. I hope that they are there, for they have such lovely flowers and draw in bees and butterflies as well as hummingbirds.
I am happy you got columbines in your yard! It must be amazing to discover new flowers in your yard :-). I hope you will soon get to see hummingbirds there as well.
In the meantime, I'll try to make it to the Botanical Gardens here in Bucharest and see if they have columbines or catmint :-)
