2. Market umbrellas - it looks great in the above photo, but, again, my garden style just doesn't have a place for them.
3. Japanese gardens - my garden is in the Midwest, and it looks it. In addition, it would be too difficult to confine myself to such a narrow plant palette.
4. Roses - they are beautiful, and some, such as the David Austin rose 'Sharifa Asma,' have a heavenly scent. I just don't want to have to deal with the Japanese beetles (that's what my Rose of Sharon is for) and the fertilizing and other regimens that go with roses. Moreover, any rose I grew would have to be scented. Sadly, NIMG.
5. Gladiolus - they are too stiff, so that I find them hard to use in a mixed border.
6. Tropicals - as shown in the last photo of my "Walkabout" post, tropicals, such as Corydaline, can be beautiful. They are just too much work for me, and they seem out of place in my naturalistic gardens.
9. White gardens - Sissinghurst is beautiful, but, most white flowers age to a ratty beige. I try to avoid them, however, this beauty can stay. Anemone 'Andrea Atkinson' sheds its petals before they turn brown.
10. Delphiniums - me trying to grow Delphiniums is like being a Cub fan: each Spring starts out with such hope, only to end in bitter disappointment come Fall. I long ago gave up on both.
