Early and frequency pruning or pinching is the key to producing a full container. Can be open and leggy with out enough pruning early. Flowers on new growth so you will want to stop pruning by early June to allow flower buds to set.

Grower Tips: 

This adaptable native plant produces huge flowers (as much as 12" across) and is both reliable and beautiful. Flowers open green, then mature to white before turning green at the end of their life cycle. Very cold hardy Incrediball blooms on new growth so even very cold winters won't keep it from blooming. The flowers are held upright on very sturdy stems, so they don't flop like 'Annabelle' will.

Prune back in late winter to encourage strong new growth and flowering. Flower color is not affected by soil pH. Best in moist, well drained soil but adapts to most sites.

Do not move outside
