Question
QUESTION: Dear Ms. Serafin,

Why are there so few blue flowers in nature? (Really blue, that is, not just bluey purple). Are there any turquoise flowers?

On a related note, how can I get dayflowers (Commelina communis) to grow in my yard? There are plenty of them growing in the neighborhood, but I don't seem to be very good at transplanting them.

ANSWER: There really are quite a few blue flowers out there: liverleaf, forget-me-not, alkanet, viper's bugloss, Jacob's ladder, speedwells, larkspur, blue-eyed grass, irises, bellflowers, wild hyacinth, gentians, spiderwort, monkshood, asters, chicory and many more.  Of these, forget-me-nots, alkanet and Italian bugloss are the closest to turquoise hues.  There are some tropical plants, wildflowers in their native habitat, that have true turquoise flowers.

As to the dayflower, collect seed and sow it where you would like it to grow, for best chance at success.

QUESTION: How do I collect dayflower seed? Do I just take a pod? And how deep do I plant it? (Or does sow mean to srpinkle it on the ground?)

Thank you

Answer
Wait until the seed pods turn brown.  Once they begin turning brown, observe closely (daily) to collect before the pods open and scatter the seeds.  Just sprinkle them on the ground.  You can cover them very, very lightly with sand or milled sphagnum moss.  It is a good idea to water them in except in hot, dry weather, when you do not want to encourage immediate germination lest the new seedlings dry out and die.
