January 31, 2013
If you’re looking for a sure winner that’s tried and true, Geranium ‘Azure Rush’ is it. A sport of Geranium ‘Rozanne,’ which was the 2008 Perennial Plant Association Perennial Plant of the Year, this cultivar features all the same great traits with a few distinctions. ‘Azure Rush’ is a lighter blue color than ‘Rozanne,’ and it ambles while ‘Rozanne’ rambles. This means it is more compact with shorter internodes, resulting in a neater, low-growing, mounded habit.
Turn up the heat and ‘Azure Rush’ continues to thrive, providing long-lasting color from late spring through fall. It also boasts:
• Amazing flower power with large 2.5-inch flowers
• Vigorous growth, compact and self-branching
• A mounded habit that is 18 to 20 inches tall with a 24- to 28-inch spread
• First-year flowering
• Hardiness in USDA Zones 5 to 8 and AHS Heat Zones 12 to 2
This long-lived garden perennial is a good groundcover with an ideal habit for patio planters, window boxes and hanging baskets. ‘Azure Rush’ can be grown in sun to part shade, tolerating summer heat better in partial shade and with ample moisture.
Easy To Grow
Transplant liners into 1-gallon or 8-inch pots with one plant per pot, using porous soil with good drainage. Plants should be grown moist. Do not let plants wilt hard. Fertilize with a constant liquid feed of 150 ppm nitrogen. No pinching or maintenance is needed.
Vernalization is not required for flowering. Plant unvernalized liners for finished flowering plants in about nine to 10 weeks. ‘Azure Rush’ can also be transplanted in the fall and overwintered in the final sales container for a vigorous spring flush.
