Gardeners' Notes:

I just planted this iris in 2016 and it is now blooming and has formed quite a large clump in my zone 5b iris garden in just one year. Even though it's yet another purple, the markings on it are quite distinctive and attractive. I've had a few new iris rot this year due to the amount of rain we've had but Celestial Explosion has adapted well. Very nice iris!

CELESTIAL EXPLOSION: (Richard Tasco, R. 2003). Sdlg. 96-TB-08-35. TB 35" (89 cm) EM. "S. violet (RHS 82B); style arms violet, old gold edges; F. cold white ground heavily peppered violet, darker violet rim; beards white with hairs tipped golden yellow, few violet tips at end; lightly ruffled; sweet fragrance. Splashacata X Colortrak., Superstition 2004." This information is reseached from the American Iris Society. This iris bloomed in its first year (2005) for me after planting in 2004. From what I've observed during that year I am very satisfied with this iris. Growth and bloom seem to be very good, and plant hardiness is equally good. Very attractive flowers!
