Hi,

I have a flower bed against the length of my house. The house is brick and it receives southern exposure, resulting in a great deal of reflective heat.

Two plants especially, a veronica and a heliopsis, tend to wilt in the afternoon sun, but after several years of otherwise thriving, it doesn't seem to be a water issue.

Any thoughts on protection to reduce the reflective heat?
Thanks!

My thought would be, take advantage of the special micro-climate and grow things there that love heat (and probably drought). Lavender and other herbs and similar mediterranean plants, for example. The spot is probably less cold in winter, too, so you might be able to stretch your zone up a notch there.
Anyway, that's what I'd do. I'm always looking for micro-climate niches where I can grow things I really shouldn't be able to.

Wilting is a natural response by the plant to conserve moisture. If they don't respond to water but perk back up when the sun moves off them, they are probably fine - and it sounds like they are doing OK. That said, however, Mara is right that something more adapted to the hot location might be better suited for that spot. Russian Sage comes to mind. I think the Veronica, with it's smaller leaves, is probably better able to take the conditions. Daylilies might be a better alternative than the heliopsis though.

if you want to reduce some of the reflected heat, how about putting up a trellis and covering it with some very leafy vine?

thank you for your ideas; not surprisingly, I have a lavender right next to it that is absurdly happy!

I agree, take advantage and grow something more exotic. There are a number of hardy succulents that might thrive there. Or something madly tough like Cistus, are any of them hardy enough for you?
