How Many Mini Calla Lilies and Hydrangea Stems for a 3.5-Inch Square Vase?

For a 3.5-inch square vase opening, one jumbo hydrangea stem is usually sufficient—white varieties are currently very full with long laterals that can be cut individually to fill space.

Mini Calla Lilies

Use 15–20 stems for a full look. Costco or Trader Joe’s often sell 20 stems for $7–$9, while florists charge ~$30 for 10. Always do a sample arrangement first to gauge the look and stay within budget. Callas are thin, so they add elegance but not bulk.

Budget Reminder

Reception flowers are temporary; prioritize your overall budget over excessive flower counts.
