No, this is not a Paris daisy. It is a common euryops daisy, Euryops pectinatus. It is obviously related, but the flowers are bright yellow rather than clear white with yellow centers, and the foliage is darker green. It is more resilient, so became more common in landscapes as quickly as mow, blow and go ‘gardeners’ replaced real gardeners who actually know something of horticulture. There is certainly nothing wrong with it. It is just cliché.
The few remaining Paris daisies are fancier cultivars of the old fashioned traditional sort anyway. Some bloom pale pink. Some bloom pale yellow. Flowers might have fluffy centers of the same color. Foliage might be pale grayish green. Plants are more compact. The cultivar that most closely resembles the old Paris daisy has more profuse, but smaller flowers. The cultivars are all quite nice, but are not quite the same as what we remember.
The original Paris daisy, Chrysanthemum frutescens, which is now known as Argyranthemum frutescens, was the sort of flower you wore in your hair if you were going to San Francisco in the late 1960s, or according to my memory, in the very early 1970s. It looked just like the three plastic daisies in the upper right (or lower left) corner of those cool AstroTurf door mats that were so popular. Perhaps they were cliché for their time too.
Cuttings rooted in half pint mason jars on kitchen windowsills to replace older plants. Our mothers grew them in the garden, supposedly to repel the bad insects, and attract the good insects to eat the bad ones who did not take the hint. In that regard, Paris daisies were how young horticulturists learned about vegetative propagation and ‘integrated pest management’ (IPM). They were so familiar back then; but then disappeared by the 1990s.
Only recently, Brent, my colleague in the Los Angeles region who I so frequently mention (typically in a disparaging manner) found just two specimens at a nursery in Southern California, and promptly procured both. One if for his garden, and one is for mine!
