Beautiful spring day -- Dallas

Missed the last two days of posts as my traveling computer decided it didn't really want to connect to the internet. Looks like I will have to upgrade soon. In any case, we have a beautiful early spring day here in Naperville, so I thought I would post a shot I took last week from the Dallas Arboretum. Anyone know what kind of flowers these are? I took some pictures of the flower signs, but this grouping didn't have a sign associated with them? Anyway, lots of great color for a nice spring day.
