When should I sow geranium seeds indoors?

Question:

When should I sow geranium seeds indoors?

Answer:

Geraniums are relatively easy to grow from seeds.  However, geranium seedlings are slow growing.  Geranium seeds should be sown in early to mid-February to produce flowering plants for spring.  Flowering occurs approximately 13 to 15 weeks after sowing.  Suggested seed-grown geraniums for Iowa include varieties in the Elite, Orbit, Maverick, and Multibloom Series.  (A series is a group of closely related varieties with uniform characteristics, such as height, spread, and flowering habit.  Generally, the only characteristic that varies within a series is flower color.)
