Something that does well in the sun

[ben01]

I want to do a couple of hanging planters along a fence that borders my property.

The area gets sun pretty much all day. I expect that any hanging planter is going to dry out real fast in the area, especially in the hotter days of summer. But it would look so good to have some nice, colourful flowers there.

I love the qualities of impatiens: they are beautiful flowers that constantly bloom and replace each other. I have had impatiens that have done really well in alot of sun, but I wouldn't try them in a hanging planter in the area I'm thinking about; they would probably be dead in a day or two.

Any suggestions? I am looing for something with lots of colour, that blooms alot and doesn't need much deadheading. I am diligent about watering, but it would have to be something that can tolerate dryness.

I'm in zone 5a or 5b.

Portulaca or Iceplant would do well in those conditions.

As Lyn says, Portulaca would do well in those conditions. Trailing portulaca is available these days too. Of course geraniums like the heat and dry soil, and I always have trailing geraniums in my full sun hanging baskets. Lantana is another one you might consider.
We've just spent a few weeks in the Californian desert area; very very hot dry conditions during the day, where Lantana thrives and the hummingbirds love it! Bonus!

I've seen some spectacular tender succulent hanging baskets, which of course wouldn't survive the winter, and I've done some with Sempervivum and Sedum which can make it - even still hanging up!
