I'm going to guess that what you have are iceland poppies, poppy nudicaule. Sometimes called naked ladies, they have thin wirey stems devoid of foliage, 10 to 18 inches long, springing from a low clump of basal leaves.

Colors range from white to intense shades of yellow and red and all the pastels between. It is maybe the one poppy that can be used as a cut flower. If picked as the bud breaks, they look great for about 5 days.

Now the bad news. They like a cold climate and will never survive an Arkansas summer. Here in the south they should be grown like pansies are, started in the summer from seed , planted in fall. Spring purchased plants may have a few blooms, but soon die of the heat.

I've never seen these plants for sale in the fall here, so if you want a bed of these spectacular blooms you have to grow them yourself.

Start the seeds in mid August inside in the coldest room in the house. As soon as they sprout give them 14 hours of bright light. Even slightly over or under watering and you will lose the whole lot. They are very slow growing to start, a plant for the advanced gardener with experience with growing fromm seed.

If you are lucky enough to get a few to October, then they turn into harty stong little plants that can be set out for almost certain success in the the spring.

Check the link below for a bed I had a few years ago.
