Cerinthe major (blue shrimp plant) is an annual growing 18-24 inches tall. Space plants about 8-12 inches apart. It blooms throughout spring, summer, and fall. It attracts butterflies.

This is a self sowing plant and you will have plants popping up the next year from seed that dropped off the plant the previous year. I sowed the seed a couple years ago and haven't had to since. Every spring I have seedling coming up from the previous year plants.

Thank you! The seedlings came up big like sunflower seedlings. Hope they aren't a nuisance plant tho!
