Aster (Callistephus Tall Double Gremlin Yellow) – With an upright growth habit and reaching nearly 30 inches in height, these Aster Callistephus flowers are show stopping! Grown from Aster seeds, Tiger Paw Asters, are not only tall but they also have huge, double blooms that have many curved petals. This yellow one is brilliant and glows with color. This Aster variety makes a great cut-flower too!

Start Aster seeds indoors 6 – 8 weeks before the end of frost, or for areas with long growing seasons, the Aster  seeds can be started directly outdoors in a prepared seedbed. This Aster is very heat resistant and virtually worry free. It will produce non-stop blooms from summer until the first hard frost in fall. Deadheading helps to keep the plant tidy and promotes continuous blooming.
Start the Aster seeds in the early spring. Press the flower seeds into the soil and lightly cover them. Transplant Aster plants outside into a position of full sun to partial shade. They also prefer well-drained soil.
