Although I'm a bit angry with the garden right now (which is, I know, irrational - it's an inanimate object - but it's true nonetheless), there is one thing I like and will plan to do again next year.
I've had a pair of these iron urns for three years now, and have not been completely satisfied with the annuals I've put in them - until this year. (The second of the pair is on the left side of the steps that are barely seen on the left in the photo.)
In the past, the trailing annuals I've planted here have tended to become dehydrated fairly quickly. The pot is metal and has a narrow throat, so it dries out quickly.
However, I really like the way this calibrachia (million bells)* spills out of the pot, and it has yet to dry out. I also like the combination of shapes - it all seems quite graceful to me. Plus, not only does it spill over the sides of the urn, it also covers the top of the dirt, so that when you look down at it from the steps or the upper garden, you don't see any dirt or leggy branches.
I will do one thing differently next year, though - I'll plant some plain maroon "spikes" rather than the ornamental amaranth. The amaranth is too tall, so it looks out of proportion (I couldn't even fit it in the photo). Plus it looks too "coarse" - like I planted a stalk of corn in the middle of a rose garden.
