A zonal Geranium is actually a type of species or hybrid. The earlier ones used to be (and in many cases, still are) marked on the leaves. Seed Geraniums are simply plants grown from seed instead of cuttings. They are both fine and there is no difference except in price sometimes.

For fertilizer, I use whatever I have on hand. Anything for flowers and vegetables is fine.

I see you are in Zone 5. I am too, the Kansas City area. Here we get "bud worms" that ruin our Geraniums in July. But I have noticed the bud worms don't attack my ivy geraniums just the seed or Zonal geraniums. You might take that into consideration when choosing if the bud worms are a problem in your area. Just this morning I bought hanging baskets of ivy geraniums at W-M for $10 each and there are 4 ivy geraniums in each basket, a bargain for ivy types! Last week I paid $4 each at a nursery. Good luck with yours.

I prefer zonal geraniums. Seed geraniums have smaller and less blossoms.They are cheaper, but I guess we get what we pay for.

I've been hunting for Ivy Geraniums, particularly variegated forever.
A few years ago, they were sold in annual hanging baskets along with other plants.
Does anyone know whre Ivy Geraniums are sold? Thanks, Toni

Is it true that zonal geraniums winter over bare rooted in the house, better than seeded ones?
