Flower(s) with the most colors

Could someone please tell me which flowers are naturally most colorful (with blues, reds, oranges, yellows, apricot, etc.) and which don't have to be hybridized? Thank you in advance.

Do you mean as far as things you can grow from seed, or bought at nurseries, or what ? Not really understanding what the question is.
There's no species of plant that has every color naturally in it's genetic make up. It will always be "missing" one of the shades.

i.e. there is no "blue" zinnia or a "yellow" Delphinium...

So many plants have been hybridized over the centuries that you'd really have to do some research to distinguish what's natural and what's not.

Butterfly weed is a real pretty vibrant orange. It grows wild around here but it's got a long tap root so it's hard to dig up (this makes it real drought tolerant too). I ordered mine from High Country Gardens. Mexican Flame vine is real pretty bright orange too (I just got some of this thanks to beckygarderner). Butterflies love both of these plants. A good purple is May Night salvia (butterflies like it too). Coreopsis is a nice bright yellow. Just a few ideas to get you started.

I'm with JasperDale, I think we need some more info on what you're looking for. If you're looking to get a variety of colors in your garden with minimal effort, then buying a mixed pack of wildflower seeds or something along those lines ought to get you the mixed colors you're looking for, but it won't all be the same type of plant. But there are a lot of reasons not to plant a garden with all the same kind of plant--even if you get one that comes in multiple colors it's still a monoculture, and if it turns out your area isn't the ideal climate for it, or there's an insect or disease that comes in and kills them off you won't have anything else to enjoy if that particular plant doesn't work out.

Thank you.

Poppies red orange yellow and white, Lupins purple, pink, red, yellow/cream.
Delphiniums purple blues of all shades, cream. Roses white, cream, red yellow plumb peach etc. Chrysanths, all the above colours and deep orange too. Daisies, white, purple pink and as many shades of white as you would want, If I were you, I would go to the library / book store and look through some books on flowers that will give you even more ideas and insight into what plants give the colours you are looking for, remember, depending on what colour of neighbouring plants/colour you choose, things look different set beside each other, there are also as many shades of green too with veriagated foliage that give lots of colours to enhance other things, so try look at pictures till you get a better idea of what kind of plants you want, some plants flower one year only while others flower year after year. hope this helps you a bit. Good luck. WeeNel.

Thank you, WeeNel, that was the information I needed.
