‘Azure Rush’ is lighter blue than ‘Rozanne,’ and it ambles meaning it is more compact with shorter internodes, so you'll have low-growing, mounded plants - 18-inches tall and 24-inches wide per plant.
Best with average, medium-moist, well-drained organic soil with afternoon shade. Best grown in full sun with some afternoon protection. Organic soil just means add compost to whatever you have in your garden so the drainage is good and the roots don't rot.
After the first blush of flowers, you can sheer them back for a second bloom. Feel free to remove scraggly side shoots to tidy up the plantings. Plants may be cut or sheared back to rejuvenate, shape and/or encourage additional bloom.
And the 2-inch wide flowers bring butterflies. No doubt where the name Jolly Bee came into play for Rozanne. No serious disease or insect problems.
Nice for containers and window boxes, rock gardens, or the front of cottage gardens.
