Zonal vs Seed Geraniums: Difference and Comparison

Zonal and Seed Geraniums share many of the same traits. They can grow to different sizes, colours, and textures, and even develop new varieties. Both of these geraniums are good for one’s garden though the difference is mainly based on the choice of one and their garden’s plants.

Below are some key differences between these two varieties.

Key Takeaways

  1. Zonal geraniums have rounded leaves with a distinct dark zone; seed geraniums have smaller, more delicate leaves.
  2. Zonal geraniums produce larger, showier flowers; seed geraniums display smaller, more numerous blooms.
  3. Zonal geraniums propagate through cuttings; seed geraniums grow from seeds.

Zonal vs Seed Geraniums

The difference between zonal and seed geraniums is how they are propagated. Zonal geraniums are propagated from cuttings. Seed geraniums are grown from seeds. Also, zonal geraniums produce more giant flowers and leaves than seed variations.

Zonal vs Seed Geraniums

Zonal geraniums got their name because of the dark zone surface on their leaves. These dark zone patterns look purplish-bronze or dark green.

These marks are circular. The leaves of them are pretty different; they are round or kidney-shaped. Cuttings are used in zonal geraniums, so the plant is exactly the copy of the mother plant.

Seed geraniums produce small flowers, and the leaves are small in size as well. However, the flowers are clustered and very colourful.

Seed geraniums are seeds which are annually grown, and their lifespan is not more than a year. Also, the plant grows another set of roots below it, which later becomes flowers for the coming year.

Mostly they are known as geraniums as they are easily recognized in the market. Primarily, the term refers to a plant known as Pelargonium x-hortorum in botanical terms.

The flowers which grow resemble spheres, and the colours are of all types. They bloom in almost every colour, including blooms in shades of pink, lavender, yellow, orange, and red, except blue. Indeed, sometimes they grow in bi-colours.

And some have double petal counts as well. You will see a lot of variety in zonal geraniums; that is their best part.

The zonal geraniums thrive in full sun, well-drained soil, and organic matter; they need regular care. The flowers and leaves grow large, and a slow-release bloom booster fertilizer also helps them bloom for a long time.

Though one needs to ensure that mould doesn’t form around the plants, or it will destroy them and keep spreading. Mainly this needs to be taken care of after rain as flowers develop mould after prolonged rains.

What are Seed Geraniums?

Seed Geraniums need at least six hours of sunlight daily and should be planted two to three inches apart in potting mix. To prevent geranium seeds from rotting, lightly sprinkle the potting mixture and vermiculite after planting.
