The flowers are long lasting like other PHLOX but unlike other variegated PHLOX I find the flower colour of "Shockwave" does not clash with the foliage...and I think this foliage is outstanding...especially prior to flowering.

Here is a picture of my stand of two plants taken a week ago.

(There is another thread I had started a few weeks back extolling the virtues of this plant. Do a search.)

Have quite a few garden phlox, but just saw and bought 'Shockwave' last week.
Already planted.

Going to be interesting to see how these do; whether they like the locations and treatment.

As a perennial gardener, have not been a big fan of perennials with variegated leaves, but have now been converted.

Have had 'Norah Leigh' in our garden for about ten years. Strong, but not aggressive, latter maybe a feature of variegated leaf perennials.

Also just got 'Becky Towe'. Had it for at least five years, but it died.
Very happy to have just got a replacement.
