I'm enjoying this topic. My choices for blue flowering bulbs are for the most part in agreement with those others who live in colder climates. And as do so many of us in cold climates, I suffer from Tecophilaea envy. Just to be different, I'll suggest three blue flowered favorites which no one has mentioned. In fact, I don't recall two of the genera about to be mentioned having been mentioned on this list at all during the time I've been posting. First is Delphinium tricorne. This is a local native (actually just a bit west of us where the soil pH is a bit higher). Yes, this is a geophyte. It grows from a structure which will remind you of that of Ranunculus ficaria. Flower color varies, but it can be very good. Second, and this one will be a bit of a stretch for some (and all I can say to them is to remember that the term geophyte does not indicate relationship): Nymphaea caerulea and some of its hybrids. Yes, these are waterlilies. And yes, these are geophytes. The third choice comes from a genus which for some reason has not come up for discussion on this list lately or ever. And to the extent that clear, sparkling, intense blue is the criterion, even Tecophilaea is not secure of its crown in comparison. What I have in mind is Commelina tuberosa (aka C. coelestis). This one grown from root clusters which will remind you of those of a turban ranunculus. And yes, it's little better than a weed, but a very pretty one.
