This plant is beautiful. The flowers grow on tall delicate stems that wave gracefully in the breeze, and the petals themselves look like they have sparkly metallic lines through them.

Grew to approximately 3 1/2 feet high.

The white form of Agrostemma githago is very strinking as it looks like satin petals embroidered with gold thread.
This plant grows well as an annual in Calgary, Canada from a direct sowing in early May.
The plant itself is similar to a bachelor button plant as it has slim grey foliage.

Got this as a free plant (to fill the box) and it it marvelous. Tall, beautiful, dainty light purple flowers that are so abundant and long lasting. It continues to grow upright with even more buds appearing.

In the beginning the tiny buds that we saw were yellow however upon maturing within a short time, they turned to this beautiful purplish color. I would buy this again in a heartbeat!
