Only macrophyllas (including serratas in this group) have an ability to change color in response to soil conditions. Paniculatas and arborescens (Annabelles) only change color in response to aging of the flower - whites will always be white - and this includes the macs - except taking on rosy red tones or sometimes green as the flowers age. And some macs - pinks especially - are not very responsive to soil conditions and hold their color rather firmly. 'Glowing Embers' and 'Pia' are examples of those. They tend to remain rather firmly pink regardless of conditions. Even in the rather acidic soil conditions of the PNW these stay pink. Otherwise, it all depends on cultivar......some change readily, others not so much. So she was part right :-) Most blue flowered bigleaf hydrangeas can change colors but you cannot necessarily make the same statement for all pink flowering cultivars.

There are some bright pink Clematis that would work, though you'd want either an obelisk or set of tall rings to give it something to cling to. Alionushka Pink & non-clinging, so a cage or multiple rings is needed to get height. 4-6' Princess Diana AKA Princess of Wales 6-8' Andromeda - Bright pink & white - 6-12' Piilu - bright pink and lighter pink May-June & Aug-Sept, so not really midsummer, but gets great reviews- 4-6' You can find photos of all these at Silver Star Vinery: http://www.silverstarvinery.com/vines.asp Screaming pink tall summer phlox blooms all of August and September in my garden with a little deadheading. Be sure to get a mildew-free variety and one that is tall enough (current trend is for shorter types) I have found that trumpet lilies are less susceptible to red lily beetle; while they need checking, they aren't ravaged by the little buggers. You may be able to find some end-of season sales or plant this fall for next summer's blooms in yellow, pinks and orange. There are also oriental-trumpet hybrids that seem pretty resistant and asiatic-trumpet hybrids that I haven't tried. There are some really tall (45") daylilies, and I'd imagine that some of them are orange. Probably too late in general now, but Dahlias might be good there - some are in the four foot range. Here's a tall dark red one left at Brent & Becky's, but earlier in the they have a wider choice: http://www.brentandbeckysbulbs.com/summer/productview/?sku=69-08 Sunflowers come in bright yellow, but also in an orange rust blend that may read as orange as well as mahogany and rust tones, all of which would blend well in a hot garden. Annuals. If you have a dry spot, some of the western Agastaches, such as 'Desert Sunrise' are supposed to reach between 3 1/2 and 4' and they come in bright pinks and oranges. In my garden they bloom August and September. High Country Gardens has a good selection of Agastaches and some are on sale now: http://www.highcountrygardens.com/catalog/search/products/agastache Post a photo later this summer so we can see how it turns out and what you've ended up with.
