Karin,
I'm glad you mentioned planting in full sun vs. less than full sun. Sometimes scapes on spiders and Unusual forms WILL lean toward the sun if they are planted in too much shade, at least in this climate. I personally have noticed this more on diploids with slender scapes. I try to grow anything that tends to "flop" in full sun which really helps. Of course, this might be less of a problem in a different climate. ( I'm in the Mid-Atlantic, on the edge of zones 6/7. )
Someone mentioned Lola Branham "flopping" for example. Here it grows in full sun - no problem.
