Germinated very easily and grew strongly in our peat free compost. Planted out in some tough spots - windy site, lots of competition from wildflowers and dense planting - yet it has powered in and is now bursting into flower. Beautiful in bud, flower and seed head. The bees love it and so do we!

But have been spectacular this year! Admired by neighbours and adored by the bees! Over 8 feet tall and covered in flowers these have given me the height and movement to the garden I needed. I like the soft yellow colour which blends with many other plants. Now late July, the flowers have faded and left wonderful seed heads which I will leave for the finches to see if they enjoy them as much as the verbena bonarienis seed heads. I am so pleased I gave this plant a try!

Thank you for your review. We are sorry to hear that the plants did not flower in their first year, being first year flowering perennials we would expect them to. However, with the unusually cool and wet summer of 2021 this may have been a factor. We have contacted you directly to find out more. It sounds like they have put on a wonderful show for you this year and hope they continue to do so for many more years. The Chiltern Seeds Team.

Germination Instructions
Sow indoors. Sow Jan-Mar. for 1st year flowering, Apr-Aug. for flowering the following year. Sow 2mm deep into moist, well-drained seed compost. Cover with a sprinkling of vermiculite. Propagate or place in a polythene bag to keep the moisture level constant. Ideal temp. 18-21°C. Avoid direct sunlight. Germination takes 14-21 days approx. Transplant seedlings when large enough to handle to 10cm pots and grow on at 10°C. Pot on if required or acclimatise and plant out with 30-60cm spacing.
Growing Instructions
Prefers a fertile, moist but well-drained soil in full sun or partial shade. May require staking in exposed situations.
Cultivation Instructions
Cut back after flowering. Deadheading will extend the flowering window. Will self-seed freely if you do not deadhead.
When to Sow
