Tip for best cut flowers

Cut the blooms when the buds are just beginning to unfurl. So you have cut them before the bees have their fun. This helps to extend the vase life of the flowers.

Bee & pollinator magnet

Bees and all our other other pollen loving flying friends make a “bee-line” for these lovely flowers.
Because the pollen rich centres provide such a long and nourishing food source for essential pollinating insects.

Rarely troubled by pests & diseases

There is little maintenance other than cutting bunches of blooms for vases.

Bring French style & class to the garden

So it is no wonder that Cosmos are traditional companion flowers in all the best (and prettiest) French potagers and orchards.
‘Rubenza’ just adds the extra wow of clouds of colour.

Compact & bushy

Cosmos bipinnatus ‘Rubenza’ is a hardy and easy to grow annual.
Compact 50cm. High in bloom x bushy 75cm. Wide of ferny foliage, depending on conditions.

Sowing tip for commercial flower farmers

Cosmos bloom most heavily when the daylight hours are 14 hours per day or less, unless they are mature before the very long days are upon them.
So for the heaviest and longest blooming crops – get your Cosmos seeds growing early indoors, and have them planted out, well grown and established before mid-summer.
Then sow a later crop to mature by mid-summer, because these will crop very heavily during autumn as the day lengths shorten.

Cut & come again

Cosmos really are “cut & come again” plants.
So the more you cut blooms, the more they will produce.
Deadheading any spent blooms will also keep them in vigorous flower production.
