Assuming that you bought Eschscholzia californica, they like full sun and dry conditions. I'd suggest growing these in a container (use cactus mix potting soil) and placing the container in the sunniest spot on your property.

Had them reseeding here for many years. Ones coming up in better soil grew big, soft and floppy. If your whole garden is shaded you may see effects of that, definitely not a shade plant. Speaking of rocky slopes, probably the one place I have most often seen these growing wild here in recent years is a steep barren slope along I-5 in Seattle, where there was a scattering of them for some time.

Here these have a pansy-like cycle, with germination and growth occurring fall-winter and bloom starting in spring or early summer - and attractive presentation, with compact display of closely spaced flowers not necessarily lasting through the hot time of the year - dry season conditions may even bring on foliage mildew. Nevertheless, some individuals may hang on for more than one year.

Unless there's another close relative that looks remarkably like the orange headed flowers -- these grow like weeds (esp. as I didn't plant them) in my yard. They grow in my beds and out the crevices of the rock wall. I think it could work well with daffodils, the bloom time doesn't overlap, both seem to be pretty persistent growers.

Definitely can be perennial; the leaves die back in winter but the single tap root gets to be quite established. They self-seed prolifically, too. I usually end up pulling them out by the handfuls after the blooms start petering in the summer.

The worse the soil the better they seem to grow from my opinion. They grow in my gravel driveway like crazy, you need a jack hammer to penetrate that soil it's so hard and nasty. I've thrown them in planter beds where I have good garden soil and they don't do well at all but in dry/sunny/nasty soil situations they thrive. Definitely as much sun as they can get otherwise they are floppy.
