Cosmos bipinnatus, Asteraceae
Cosmos Rubenza is prized for its large, deep ruby-red flowers, which take on an old-pink hue as they fade. It's a cut flower that holds well in a vase, and blooms early. Around 80 cm high, it can be grown in containers as well as in flowerbeds.

In stock
Sow in situ after any danger of frost when the soil reaches a minimum of 16 ˚C, ideally between 20 ˚C and 25 ˚C, and aim for 25-30 cm plant spacing. Alternatively, start seedlings indoors 4-5 weeks before transplanting after the last expected frost. Grow in full sun, whatever the soil, preferably even a little poor. Cosmos don't like wind very much... You can pinch back the main stem when the plant reaches 30 cm to stimulate a bushier growth habit.
