From Seed Geraniums have been a popular bedding plant for many years. Plants traditionally are grown from cuttings. In recent years, however, seed-grown hybrid geraniums have become popular. The popularity of seed-grown geraniums has increased because they often outperform the older geranium varieties propagated from cuttings.
Geraniums are easy to grow from seed.
However, they are rather slow growing. Sow seed in mid- to late January to produce flowering plants for spring. Flowering occurs approximately 12 to 16 weeks after sowing. Suggested seed-grown geraniums for Iowa include varieties in the Orbit and Sprinter series. A series is a group of closely related varieties with uniform characteristics, such as height, spread, and flowering habit.
