What is the difference between Zonal and Seed Geraniums?
Zonal and seed geraniums are both upright growing geraniums but they have several distinct differences that you should know before planting in your gardens.
1. Zonal geraniums are propagated by cuttings while seed geraniums are through seeds. Zonal geraniums are genetically advanced plants, propagated with the goal of producing sturdy, stronger zoned leaves and shatter-resistant flowers.
2. Zonal geraniums are faster to grow and flower faster than the seed geraniums.
3. Zonal geraniums are bigger and taller. They also bear bigger flowers and leaves than the seed
variation. Seed geraniums are a compact version of the zonal geranium growing less that one foot with smaller, more numerous flowers.

4. Zonal geraniums have 4-6 inch global flower heads that need to be deadheaded by removing the entire flower stalk down to where it meets the main stem. Seed geraniums natural shed their blooms in a process which is referred to as petal shattering. They will shed their colorful petals in a strong wind or rain storm, leaving the plant flowerless for a bit of time.
All of the geraniums that we grow at Crocker Nurseries are zonal geraniums and we take pride in growing them in our greenhouses producing what we think are the best geraniums on the Cape! We give them space to grow so they are able to be compact and spread out horizontally rather than being tall and leggy. We also only water them from the base with our Ebb and Flood watering system that fills the benches with water and once the plant has taken what is needed, it drains out. Watering from below keeps the water from landing on the geranium leaves and producing leaf spots and potential fungal diseases.

Thank you for info. I pitched both seed n zonal
Geraniums. Will watch how they compare
In my garden.
