Flowers – they’re everywhere! How many of us know a Rose, a Lily or a Bluebell perhaps? Let’s see: there’s Clover, Flora, Heather, Iris, Jasmine, Lavender, Lilac, Violet. My brother-in-law and his girlfriend are great friends with a lovely little lady called Petunia. And the UK chef Jamie Oliver and his wife Jools have three floral-named daughters: a Poppy, a Daisy and a Petal Blossom Rainbow. I wonder if they’ll stick with the theme when baby No. 4 arrives in autumn.

Check out this week’s video blog entry. Special thanks to the United States Botanic Garden on Capitol Hill. And if you are in DC, for more of Georgia O’Keeffe’s flowers check out the exhibition running at the Phillips Collection through May 9th.
