woofie said:And are they different species of morning glories? I. purpurea typically will bloom sooner than I. nils and I. tricolor. At least, that has been my experience here.

What woofie said.

Night temperature differences can make a difference also. Many plants, not just Morning glories will bloom less or even not at all when night time temps are higher. Our night time temps here have been around 78- 80º,. Don't know what yours have been but that might be having an influence.
