Unusual Light

No, it's that there are more things in bloom and leafed out than there usually are when the sun is at this azimuth.

 In that light, the species tulips glow. I always prefer them closed to open.

And much like the daffodils near the park, these are gaining aphids. With so little soft vegetation for all those winter-surviving aphids to tap, they've been found in the less than usual places. Chrysanthemum stems, daffodils, and now the species tulips.
