When buying real touch calla lilies, appearance is only the starting point. Confirm the minimum order quantity before discussing colors, lengths, or custom cartons. A low MOQ may suit a trial order, while larger quantities often support better shade consistency. Ask for written figures, not verbal estimates.
Stem gauge needs equal attention. Specify stem diameter, length, flexibility, and acceptable tolerance in millimeters. A stem that looks elegant may bend during arranging or shipping. Request a production sample and measure it yourself. Small differences matter. Keep records.
UV performance should be verified through ISO 4892-3 testing, not vague claims like “sun resistant.” Request the test method, exposure cycle, irradiance, duration, specimen photographs, and color-change evaluation. The test does not guarantee unlimited outdoor life. Conditions still differ between a bright shop window and a humid garden.
Packaging should protect petals, stems, and surface texture separately. Check inner spacing, moisture barriers, carton strength, drop-test results, and pallet stability. Ask whether each lily has a sleeve or a shaped divider. Inspect a packed sample after simulated transport. It may reveal crushed tips or bent stems. Those details are easy to miss during approval.
A reliable supplier should provide traceable batch information, inspection records, and clear replacement terms. Be careful with attractive samples; production quality can vary.
