Buy Cobaea scandens f.alba white-flowered cup-and-saucer vine: Headily scented, white cups

  • Position: full sun
  • Soil: moderately fertile, moist, well-drained soil
  • Rate of growth: fast-growing
  • Flowering period: June to September
  • Hardiness: tender

    This fast growing, evergreen perennial climber will quickly cover a sunny wall, arch or obelisk and produce large, sweetly-scented flowers from midsummer to the first frosts. A rarer form of Cobaea, the white bell-shaped flowers add an exotic touch to a summer planting scheme. Plant it near a window or busy pathway to enjoy the perfume.

  • Garden care: Sow the seeds horizontally, 1cm deep in deep pots using freely-draining compost and water well. Keep them warm under glass (ideally at 18°C) and pot on when large enough to handle. Harden off gradually and plant outside after all risk of frost has passed. Plants can be overwintered under glass, but are mainly grown as annuals in the UK.

  • Sow: February-May

  • Flowering: July-October

  • Approximate quantity: 15 seeds

I found the seedlings, although healthy and good germination rate, did not do well on the patio as I had hoped. I think the wet summer and late heat did not help with this plant. I also did not find the flowers fragrant. It is a pretty plant, though and might do better as a large conservatory plant. I suspect most of my friends would not have the patience to germinate this plant, so would not recommend the seeds.




Vigorous climber


Purchased these seeds and the germination was excellent. Very vigorous growth throughout the Spring and Summer and all the plants are still looking extremely healthy despite the fact that we are now well into December. Perhaps this is because all the planting occurred on a relatively sheltered terrace in Italy. The only negative feature of the plants is the flower colour ( not very significant), perhaps I will purchase some bi-coloured seeds the next time.

Not trying this again next year


Always fancied growing one of these climbing bells. Was disappointed: germination was sparse (3 out of 20), it needed a lot of attention and watering, staking and tying in and then the pot fell over with the slightest gust. Perhaps it should have been trained over an obelisk. Bell shaped flowers look sophisticated in white and with green tinges, though were not as prolific as I had hoped. This plant is apparently able to continue another year if you overwinter it somewhere warm, if you have the space.




I think we failed them.


Reluctant to leave a poor Review because they germinated well and were developing into healthy looking young plants when my husband had transplanted them in the garden. Then they just disappeared. We don't know if something scoffed them or they didn't like the move, the soil conditions and/or the position wasn't right for them. They were alright when they left me in the polytunnel. I've bought more of the same seeds this year to try again though from a different catalogue.
