There is no other plant with flowers this colour – true Verdigris; when copper oxidises to give this incredible, vibrant Aegean sea blue.

Tweedia coerulea is an excellent small container plant, and cuts well (although not prolific), but most of all it’s an exceptional and unique border plant for a sheltered, sunny corner. If you over-winter, out of the frost, it flowers bigger and better from one year to the next. You have to grow it!

Sowing, Seeds, Planting Sow indoors in spring; sprinkle seed thinly and cover lightly, placing somewhere warm until seedlings emerge. Pot on and move to a cooler location. Harden off before planting outside after last frosts. Only reliably hardy in the mildest of gardens, so grow as an annual or a conservatory perennial. Evergreen when kept above 5°C. Plants raised from seed flower quickly, only a few months from sowing.
Care Tips Left to grow naturally, plants are thinly branched, but frequent pinching out of the growing tip while young, produces bushier plants. Provide support for the climbing stems.
Flowering July - October
Vase Life Sear stem ends in boiling water for 10 seconds.
Harvesting Flower production: 3-4 months
