Is it possible to collect seed from Profusion zinnias and then grow them and get plants true to the parent?  I've been growing orange and yellow Profusion zinnias for years, but this year I had trouble finding them locally, and the ones I did find were not real fresh-looking.  A few are struggling to put out growth.  I'd like to try growing them from seed next year if I can get true plants.

I can't answer the question about Zinnias coming true from seed, I am sure someone will answer that.

Have you grown Zinnias from seed before? With the warm soil this time of the year they grow really quickly from seed directly planted shallowly in the garden. I just planted mine this week and in two days they were popping out of the ground. I see that seed is available online for you to get them growing this year.

No, I have never grown zinnia from seed.  I already have this year's plants.  I'm sure the lagging plants will begin growing soon.  I'm keeping the blooms pinched off so they'll put their energy into growing.  As some of the other, more robust, plants put out new blooms I'll try experiment with collecting and sowing seeds.

It is a hybrid so the seedlings will probably be somewhat variable. Mine come somewhat true. Like you the late spring delayed volunteer germination. It is really OK since the power of Zinnias asserts itself in July. Zahara and some of the tall zinnias are just forming their first flowers now but the Profusions are still quite small, even those that were started indoors. No Zinnia pinching here I just back away and let them do their thing.

Aren't the Profusion zinnias grown in the little 6-pack cells grown from seed?

I've never knowingly seen a zinnia volunteer.  Maybe I have, but I just figured they were weeds so I pulled them.

They are grown from seed and are probably a fairly stable hybrid. But if they exposed to other zinnia hybrids and species like in someones garden the results would be unpredictable. I buy seeds not plants. Profusion genes get into my volunteering Zinnia angustifolia leading to variable plants. It isn't something I mind particularly.

You could be weeding out zinnia volunteers although they do look pretty obviously zinnia. Maybe you are too cold for the seed to survive over the winter on the ground?

Profusion zinnias are the only zinnias I've ever grown, so there wouldn't be any mixing.

Regarding volunteers, the only ones I really pay attention to are salvia and agastache.  Basically, if a little seedling isn't an obvious one of those, I pull it.  I've never even considered the possibility that a seedling could be a zinnia.

From what I remember in my searches/readings, normally, zinnia seeds are not true.  There is one exception and if I remember correctly (almost sure) it's the profusion series.

We get seed for tall red zinnias from Wild Seed Farms in Texas---they always do well for us.  I have never seen a zinnia reseed in our zone 5a yard.
