Are these planted in the ground in a flower bed or are they for pots? Where are you located?

I am in Massachusetts. I have a small area near my front door and used to plant impatiens. I am substituting NG impatiens due to the mildew problem. But they don't spread the same and need something between them. I bought red and orange since my house is dark green. Thanks.

How about something white like diamond frost?

Sweet potato vine if the area is sunny enough, English ivy or small ferns if it is shady.

Lantana goes well in a bed area and comes in a red/orange combination as well as yellow. It spreads pretty quickly. I also like Purple Homestead verbena which I mix with reds or purple million bells.
