I find this plant very charming. The blooms are a true pink. The leaves are blue-green which compliments the pink blossoms. They are about 7 inches tall in bloom. They bloom early spring. It's April 23, and they have started blooming. They are supposed to be in full sun with excellent drainage. Mine get about 7 hours of sun in the middle of the summer. They get western shade. I have them on a terrace so they have very good drainage. Mine have not reseeded. I winter sowed mine. They germinated and grew to maturity easily. About once a season, I pull the weeds that sneak in amongst it. I recommend this plant for your garden.

Following are some germination details for this plant:

1)Sow at 20*C (68*F); if no germination in 3 - 4 wks, move to -4*C to +4*C (24*F - 39*F) for 2 - 4 wks.

2) One site says similar to above, except give the warm temperature 3 months, and the cold temperature 1 - 2 months.

3) In the 2nd edition of Norman C. Deno's book, Seed Germination Theory and Practice, Aethionema grandiflorum was researched, but Deno thinks that other species within this genus will follow similar patterns of germination.

He noted that seed dry-stored for 6 months at 70*F or 40*F germinated more quickly than fresh seed, and that sowing the seed at 40*F had a higher germination rate than sowing it at 70*F. Seed sowed at 40*F began ge... read more
