Best and biggest zinnias for cutting

gardenerzone4(5b)August 20, 2011

Please recommend some tall zinnia varieties that have huge double flowers for cutting. I've grown Benary's Giants in the past but curiously, they never got more than 3" wide for me.

Next year, I'm thinking of trying some hybrids to see if I can get giant double flowers. If you have experience with these or any others, please recommend and let me know how big they get.

That is HUGE! I would be head over heels if I got a zinnia that big. What am I doing wrong? I planted Benary's Giant seeds from Territorial Seed and Park's Pick's, which is supposed to be a private label of Benary's Giants. Both maxed out at 3", maybe 3.5" for the main central flower. And that's in good soil with compost and 8" spacings. Bfff, where did you get your Benary Giant seeds?

Anyone else, please chime in if you know of a place where I can buy Benary's Giant Zinnia seeds that dependably result in giant flowers. I refuse to accept that I cannot grow giant zinnias! :-) It's now become a mission...

I got this years crop from GEO Seed.
I have in the past, had similar experiences to you with a lack of size. This year I've added Mushroon Compost (18 wheeler load) to my sandy soil and a blend of synthetic fertilisers to each row. The results have been phenomenal. I plant my Zinnias on 9" - 12" centers and normally pinch out that first bud for better branching.

for the best stems and largest flowers, I have to pinch off the side shoots.

I've had the same frustration and have found that the Benary mixtures can vary a lot in terms of colors. From a couple of sources, I got only purples and pinks.

Here is a picture of a Burpeanna zinnia from a Walmart pack. It is a first flower, and thus larger, but has been very free flowering.

I got my seeds from Territorial Seed and Park's. Haven't tried Johnny's yet. I'm growing in very good conditions, actually, all organic with lots of compost and mulch, adequate spacing (8"), and soaker irrigation. The plants look very healthy, just the flowers don't get much bigger than 3", and aren't as double--maybe 2 rows of petals instead of the dahlia look. I only cut for my home, so it didn't really bother me until I went to a local mall a few years ago and saw giant zinnias growing on their grounds. These flowers were 5-6" big easy, and I was so jealous! I should have asked what type and where bought and maybe to take seeds from them, but neglected to do so.

Are you using fertilizer as well as compost? Many people forget that compost is not really a fertilizer, merely a soil conditioner. Many growers fertilize every 2-4 weeks with both foliar and granular (organic if you so choose) fertilizer.

I have direct seeded Benary's Giants for several years.
Due to a huge seed price increase by Benary's, I trialed
Giant Dahlia Flowered Zinnias from Geo and Johnnys and was
really pleased with the results. Other than a few singles,
there is very little difference.

I've gotten my seed from Johnny's before and was satisfied.
Some of the zinias actually grew to be 7'4" tall. I measured them with a tape measure.
Jung's has a line of giant zinnias also which is similar to Benary's Giants.

There is a big difference between Benary's and Giant Dahlia flowered zinnias. Benary's actually look like a dahlia. The other not so much. Too much fertilizer makes them lanky, and they don't hold up as well as far as vase life. Also, zinnias should be transferred into very cold water after harvesting. Buckets of water should be kept in the cooler. Water directly from the hose isn't cold enough.

Benary's should be an exclusive production of some sort, so all the seed companies are purchasing from the same source.

Flower size variation then varies according to growing conditions as boston3881 notes.

I want to plant more zinnias. They bloom most of the year. And wanted some taller ones. But nice to see the taller ones. Have bought from Johnny in past. Was busy working painting house. So will have to request a catalog. I want to take cut flowers to church to share.
