Postrate or vertical foliage

Steve,

If a daffodil can have postrate foliage is obviously influenced by the genes. But I think there are some exturnal factors too which have consequences. Exposed sites with much sun, wind and no other plants nearby seem to support postrate foliage. The  light, the temperature and the time of observation during the growing period may be of influence.

In the pictures you see N. miniatus and Iris reticulata at exposed sites which normally have vertical foliage.
