Plant description
A beautiful perennial, with sumptuous, velvety, bronze flowers produced above lance-shaped, blue-green foliage from June to September. The aroma of this new variety is even more chocolatey than Cosmos atrosanguineus and it's more compact too, so may not need staking. Great for growing in a sunny border and looks lovely when planted with other hot colours.

How to care for Cosmos atrosanguineus Chocamocha ('Thomocha') (PBR):
Plant Cosmos atrosanguineus in frost-free conditions, in a sunny spot with well-drained soil, spacing the plants 30-40cm (12-15in) apart. Water thoroughly, keeping the soil moist but not waterlogged, and mulch to retain moisture and suppress weeds. Fertilise in spring and mid-summer, and deadhead spent blooms to encourage continuous flowering. In cooler locations, dig up the tubers in autumn, reduce the stems to within 5cm (2in) of the roots, and store them in a cool, dry place for replanting in spring. Alternatively, mulch with a thick layer of compost over the winter to protect the plants.
Please note:
This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.
Twiners
Take advantage and do some early spring planting, but only on clement days. You can never have too many climbers and twiners, and now is the ideal time to get them in. They take up little ground space, so they’re perfect for smaller plots, and then they g
