Hello everyone,
I'm looking for ideas for annual flowers, no yellows or oranges, for East-facing outdoor window boxes on a patio. The area gets 6 to 8 hours of sun beginning at sunrise. Any and all suggestions welcome!

No orange or yellow? How sad!

Petunias, snapdragons, Larkspurs, poppies, purple sweet potatoes.... Take a trip to the Big Box store and see what they have.

Geraniums, verbena, lantana, sun coleus, African daisies
What Daisy said: go to box stores and look for anything that likes the sun.

To Daisyl, yes it is sad about the orange/yellow thing. I'm not sure what her issue is with those colors (I'm posting on behalf of a friend) It may be that she just isn't fond of those colors. In any case, for the suggestions!

Frenchy21, as well for your suggestions. I will share your response with my friend!

Columbines ... they have many colors but mine are purple with a white center.

Anemones ... I have a pot of them that bloom red, white and blue (yes, it's to be patriotic)

Cuban lilly (Scilla peruviana) — these are blue

Hyacinths — they have purple and white varieties

And another easy plant is the "purple heart" has small pink flowers against dark purplish leaves — super easy to grow and easy propagation

Blue alliums

Muscari armeniacum also known as grape hyacinths — they are blue and can be invasive

Jasmine — white and smell lovely!!

Zinnias

Freesia

Crocus

AND .... Calla lilies come in a great variety as well

I have grown all of them in pots at one time or another ... and all are simple.

Hope that's plenty.

Bandaids! Great suggestions! I will pass them on to my friend, who I am certain will be grateful.

Lots of great suggestions but as your friend if she expects/wants flowering * all summer. That will help narrow it. Many people do not realize how many flowers do NOT keep blooming all summer.

*coleus, purple heart and others do give "color" all summer

Salvias (many kinds) seem pretty bulletproof and those I have grown keep blooming, even the perennials.

Sallyg, you nailed it. That's exactly what she's trying to accomplish, summer-long blooming colorful flowers!

I just remembered a few more plants for you (and I have grown all in pots/planters).

Spanish Lavender (shorter than English lavender)

Blue ginger — requires bright light and shade loving

Galvezia speciosa (island snapdragon "firecracker" color is red) and hummingbirds enjoy them. This plant also bloomed a couple times a year for me.

Mandevilla — mine bloomed a few times a year

Iochroma PURPLE QUEEN .... love the color and was able to get it to bloom more than once a year.

Medinilla magnifica — also known as Philippine orchid which comes in white or pink. Mine blooms several times a year. Needs bright light and is shade loving

If the patio can accommodate red bananas such as red Abyssinian ... or dwarf red bananas ... variegated leaf bananas. Not flowers but are pretty and add color like some varieties of ti.

And .... hibiscus come in a variety of colors and combinations.

That's all I have. LOL! Hope it works out for your friend.

If you buy beautiful leaves and end up with flowers too, that's a fine way to go! : + ) Except when I kill instead of grow, I'm never disappointed this way.

Medinilla, mandevilla, not going to live in the box thru winter in NY.

EVERYONE from my friend & from me as well!
