My grandmother had Hydrangeas all down one side of her semi out in Blair Street Bondi. They are a very old-fashioned flower, dare I say, an out-of-fashion flower. However, Kirsten's father gave her a vase full, and she liked them. Mainly, she liked them because as a cut flower they lasted, with minimal degradation for well-nigh three weeks. So I bought some online. Well, I actually bought two examples each of seven varieties, pretty much across the colour spectrum. But each is a mophead.
To all the floral flush discussed above, add the alternating of 'crystal palace' Lobelia with mixed marigolds, in the semi-circular garden atop the rockery, and I have a PLAN!
