Cup and Saucer Vine (Cobaea scandens) is a conversation starter. The flowers have a unique shape that merits both the common names: Cup and saucer vine and Cathedral bells. The purple flowers also have an unusual color palette that is unexpectedly muted, especially when you consider the size and shape of the flowers. But this is a vigorous vine and hard to ignore in the landscape. Although Cobaea takes awhile to start blooming, the vine itself will quickly make itself at home and create a screen or cover.
Flowers: The cup-shaped flowers are pale green as they start to open, but quickly turn purple or white, as they fill out. The opening buds have a somewhat unpleasant scent, but the fully opened flowers develop a floral-honey fragrance. The green calyx remains at the base of the flower and becomes the saucer.
Germination
Soak the seeds for 2 hours in warm water before sowing. Sow at 18-24°C in a good seed compost. Sow the seeds on their edge and just cover with compost. Keep soil damp but not wet, sealing in a polythene bag after sowing is helpful. Germination usually takes 21-30 days. Germination can take longer, don’t give up.
HOW TO GROW
Start seeds indoors 6 to 8 weeks before the last spring frost. The seeds should be sown with their longest edge pointing down. Can also be direct seeded outside, but flowering will be delayed.

Days to emergence: 10 to 24
