These were all over town 2 years ago in our 75462 area(7a) and also about 100 miles NW of us. They are native to Australia and, according to a source there, note they do have to be watered well but they even withstand the very hot Out Back sun. They don't require deadheading and bloom profusely in our 80 -100+ temperature all summer clear through frost.

I too have found the fan flower truly heat tolerant with bountiful flowers without need of deadheading. it has been beautiful in pots as long as I water daily and twice daily on really hot days. So beautiful that I would like to keep them over the winter, which in zone 7b can be rather cold. Has anyone been successful in bringing them indoors or using cuttings to restart in the spring?

Our town planted these last summer by the firehouse. They were absolutely gorgeous & bloomed from early summer through the frost. We had one of the worst summers last year, heat-wise; it was 90+ for most of it and as other annuals succumbed to the baking heat, these beauties just kept blooming! They are amazing! I finally found the name of them & bought some myself for this year. A terrific hot weather flower!!!! I'll always have these in my front yard from now on!

This is a great sun loving plant... blooms continually from May thru October.. I have a yard lined with baskets of this plant on my fence..It does need to be thoroughly watered when the weather is hot..but often I see it completley wilted and revives within 12 hours when I give it a good drink.. So if you have a sunny spot.. try it.. you will love it..

Only widely available since last year, scaevola is ideal for baskets or planters, with stems that overflow the sides while gracefully arching upwards. Vivid purple-blue flowers elicit admiration from visitors. Quite drought-resistant for a flowering plant, too. Nobody seems to know how long it will live in Nor.Cal or whether it needs to pruned for the winter, since it's so new. Note that when it was first transplanted (I have 3 of them in wall planters), however, it literally sulked for almost two months, losing flowers and looking ready to die. Then it settled in and within three weeks (May) was covered with blooms -- it is now mid-October and still blooming vigorously. It gets good south sun and is amongst white lantana, red-flowering aptenia, and jasmine, spilling over a concrete block wall.
