Harvest Tips

Rudbeckia Toto is grown for ornamental flowers, not harvesting in the traditional sense. Cut flowers for arrangements when blooms are fully open. Deadhead spent flowers throughout the season to encourage prolonged blooming. Allow some flowers to remain on plant late in season if you want seeds to self-sow. Cut back plants to 4-6 inches after hard frost.
