Choosing Your Blooms: Zonal vs. Ivy Geranium Seeds for Every Garden Spot

You’ve mastered starting your geranium seeds indoors. Now comes the fun part: deciding which stunning variety of Pelargonium best suits your gardening goals!

While every plant in the Pelargonium genus offers vibrant color and exceptional heat tolerance, their growth habits differ dramatically. Choosing the right geranium seed type—whether for an upright container or a sprawling hanging basket—is key to achieving a professional-looking display.

Here is a simple breakdown of the most popular varieties grown from flower seeds.

 

1. Zonal Geraniums (Pelargonium $\times$ hortorum)

 

The Zonal Geranium is the classic, upright plant you see filling public parks and garden beds. Its name comes from the characteristic, dark-colored 'zone' or ring often visible on its leaves.

Feature Description
Growth Habit Upright, bushy, and mounding. Typically grows 12 to 18 inches tall.
Best Used For Garden Beds, Edging, and Containers. They create dense, uniform color blocks.
Ideal Varieties Maverick Series (known for huge blooms) and Pinto Series (great heat tolerance). Excellent flower seeds for mass plantings.
Seed Advantage Zonal geranium seeds are incredibly reliable and provide the most uniform results in mass plantings.

 

2. Ivy Geraniums (Pelargonium peltatum)

 

Ivy Geraniums are the ideal choice for any planting where you want a cascading waterfall of color. They get their name from their glossy, ivy-shaped leaves and trailing habit.

Feature Description
Growth Habit Trailing, sprawling, and semi-succulent. Stems can trail 18 to 36 inches long.
Best Used For Hanging Baskets, Window Boxes, and Tall Planters. They spill beautifully over edges.
Ideal Varieties Often sold as unnamed mixes or specific trailing hybrids. They are less common to find as seed but offer a unique, luxurious look.
Seed Advantage Growing Ivy geranium seeds is the most affordable way to fill multiple large hanging baskets with professional-quality trailers.

 

3. Regal/Martha Washington Geraniums (Pelargonium domesticum)

 

While less commonly grown from flower seeds, Regal geraniums are worth knowing. They feature ruffly, jewel-toned flowers, but they tend to bloom heavily for a shorter period and prefer cooler temperatures than Zonal or Ivy types.

  • Key Difference: Regals typically stop flowering in the intense summer heat and are generally propagated from cuttings, not seeds.

3. Frequently Asked Questions (FAQ Section)

 

Q1: Can I grow Ivy Geraniums from the same seed starting mix as Zonal Geraniums?

A: Yes, both Zonal and Ivy geranium seeds require the same warm, sterile seed-starting mix and 70-75 degrees F bottom heat for successful germination.

Q2: Which geranium seed type is easier for beginners?

A: Zonal geranium seeds (like the Maverick series) are often considered the easiest to start and grow, offering a more vigorous and reliable plant that handles common garden stresses better than other types.

Q3: Is a Pelargonium considered an annual or perennial?

A: In most regions, Pelargoniums (geraniums grown from seed) are grown as annuals because they cannot survive frost. They are technically tender perennials and can be overwintered indoors.
