Cosmos bipinnatus 'Cupcakes'

Half-hardy Annual

  • Cosmos 'Cupcakes White' voted RHS garden visitors' favourite
  • 'Cupcakes White' is part of our exclusive mix

Back in 2007, US customer Diane Engdahl of Santa Rosa, California, sent us seeds of an unusual cosmos growing in her back yard. Instead of having separate petals like most cosmos, all petals are fused into one single cup, completely changing the normally daisy-looking flower. Since then our breeders have been busy fixing the unusual trait across the colour mix, developing new shades and refining the habit of this uniquely shaped 'cupcake' cosmos. The result? An easy to grow, free-flowering three colour blend of single and semi-double blooms on tall bushy plants ideal for border designs and container growing. Cosmos 'Cupcakes' was the stand out performer in our 2014 flower trials, coping well and looking great come rain, shine or drought. Height: 120cm (48"). Spread: 60cm (24").

Sow Cosmos seed from March to May at a depth of 3mm (⅛") in a good quality seed compost, and cover the seeds with a very fine sprinkling of vermiculite. Place the seed tray in a propagator at a temperature of 18-25C (64-77F) or seal it inside a polythene bag. Keep the soil damp but not wet. Do not exclude light as this aids germination which usually takes 7-15 days.


When seedlings are large enough to handle, transplant into 7cm (3") potsand grow them on in cooler conditions until large enough to plant outdoors. When Cosmos plants are well grown and all risk of frost has passed, acclimatise them to outdoor conditions over 7 to 10 days. Transplant outdoors in full sun in any moist, well drained soil at a distance of 45cm (18") apart. Pinch out the growing tip of each stem when transplanting to encourage stems to branch and produce more Cosmos flowers.

When growing Cosmos plants, water regularly until they are fully established. Deadhead faded Cosmos flowers regularly to encourage more blooms to be produced throughout the summer.

  1. weak performance

    By Yoshiko Harrop 26-10-2016

    Every year, I grow at least a couple of varieties of cosmos. Compared with others, this cosmos is a. germination rate is good. most of them germinated. b. some plants flower early and dies by late summer. Others do not flower untill late summer. c. never reached eventual height(60cm to 80cm) d. good colour mixture. Most importantly, you'll get only very little perfectly fused cupcake flowers. I had probably two plants with truly 'cupcaked' flowers out of the whole packet. Most of them have at least one or two cuts in one flower, and some have just three or four 'big fat looking petals'. A plant produces one kind of flower, i.e., if you see the first flower is completely fused, then all the flowers from that plant is likely to be fused.
