Gardeners' Notes:

These flowers are just gorgeous. They have flowered nonstop for weeks now. The bees love them, too. And as another gardener stated, they are definitely flopping over.

I am growing them in two pots on the front porch. I would say that they receive moderate sunlight. They also love to be watered every day. I may try them in the ground in the future, but they are stunning to look at each time I go in the door.

more of a question than comment. I'm a black-thumb gardener :) I have the cynoglossum from my girlfriend. I live in Botswana (I think USDA Zone 8a or 8b or 9, not sure). We're going through a rough patch, so I want to plant this and send it to her, but I only have a few seeds and dont want to screw up...planting tips anyone? I have them in a 8" pot, do I water everyday? It's hot here.

These flowers are a great shade of blue. Mine reached over 24" tall and tended to fall over at the end of the season. This is a prolific self seeder, and the seeds are stickly, so they spread about alot.

An easy to grow beauty. Reseeds itself, even in cracks and
crevices of my rock walkway. Managed to thrive despite
a few days of 20 degree weather. Blooms all summer into

I grew half of the seeds inside and half I just scattered outside everywhere. My garden is alive with little blue flowers all season.

Grow in moderately fertile, moist but well-drained soil in sun or partial shade. Plants become course and leafy and may not flower well in soil that is too fertile; they do not thrive in heavy clay soils.

Firmament is compact with deep blue flowers and gray-hairy leaves. Grows to 16" tall.

If started early indoors, 'Firmament' blooms all summer long in an incredible shade of sky blue. It can also be direct sown, or grown as a biennial, and it self-sows.
