Celosia plumosa erecta. Bright Sparks Formula brings a zap of brilliant colour to nearly any garden situation. This versatile plant is very heat tolerant, which makes it an excellent choice for containers or any full sun situation. The plants stay compact but upright, only growing to about 30cm (12") tall, and they are topped by electrically bright plumes in scarlet, yellow, and burgundy. These make long-lasting cut flowers, and they keep most of their colour as dried flowers. Bright Sparks shows more branching than other Celosia types, which simply results in more flowers per plant.
