Heliopsis – Tuscan Gold™
Native to North America
Removing spent blooms may help encourage additional blooming. Winter mulch can reduce heaving that can occur with perennials from the freeze/thaw cycles of winter. Tuscan Gold is heat tolerant and will tolerate somewhat dry soils. While deadheading may encourage additional blooming it isn't strictly necessary for a long bloom season. The breakthrough here is an easy flowering Heliopsis with a shorter plant size, outstanding garden performance and disease resistance. A long known great garden plant with good manners and a long flowering season, also makes a great cut flower! An application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.

Pinching and Growth Regulators
No PGR necessary. Pinch once for increased branching on smaller pots. Pinch 1 to 2 times for larger pot sizes.
Pest and Disease Management
General Pest and Disease practices as listed in notes. Whiteflies.
Early season production not recommended due to light quality and heat requirements. Can be grown in late summer and overwintered for spring sales OR grown in late spring for summer sales. The critical issue is daylength plants must have long days to grow and flower. ANY short days in production will cause the plants to rosette.
