Gerbera daisies (Gerbera jamesonii) stand about 12 to 18 inches high and bloom colorful summer flowers that reach a width of 4 to 5 inches. These flowers are often cut and used in floral displays. Gerbera daisies are winter hardy in USDA plant hardiness zones 8b to 11 and will grow as perennials. In cooler climates, they are grown as annuals and replaced each year. Gerbera daisies are an excellent addition to the garden and should purchased from a reputable local, catalog or online nursery.
Decide if you want to plant your gerbera daisies as seeds or as already grown plants. Grown plants will be easier to plant and care for and will be ready to bloom if they're not already blooming. On the other hand, seeds are less expensive.
Count how many plants or seeds you will need to fill your space. Gerbera daisies are planted 12 to 15 inches apart, so a 3-foot-square area will need about 7 to 9 plants. If you're planting seeds, you will need three to four times as many seeds as this number since not all the seeds will germinate and thrive.
Purchase and plant grown gerbera daisies after the last frost in the spring. Purchase gerbera daisy seeds about 12 weeks prior to the last frost of the spring, and plant them indoors. Note that it will take the seeds about 6 months to sprout, grow and finally bloom. Transplant the strongest seedlings outdoors after the last frost.
Look for disease- and damage-free plants if you are purchasing gerbera daisy plants at your local nursery. If you are ordering through a catalog or online, compare warranties, if any, as well as any customer complaints with the Better Business Bureau.
