Calla lilies in Paris: long stems carried in the crook of the arm
Calla lilies in Paris are the usual flower of the bridal "presentation" bouquet: long stems carried in the crook of the arm rather than gathered into a posy. A calla mono bouquet works the same way, so choosing one comes down to length and line, not volume.
Choosing a calla bouquet: colour, greenery and the photo
Only the Purple Calla Lilies Bouquet names its colour; for the others, the shade is best judged from the grid photo. Calla Lilies with Eucalyptus is the only one naming a second greenery, and Calla Lily Bouquet No. 2 gives no colour or greenery at all, so it's worth checking the same way. Every bouquet is put together to order once payment clears. A photo of the finished bouquet comes back before the courier leaves, so a change can still be asked for then. If a particular calla isn't in stock, the florist swaps in one close in shade and price, and that swap shows in the photo.
Calla lily delivery in Paris
Most orders are handed over the same day they're placed; exact timing for a bouquet shows on its card, with more on the delivery page. The card message is free, signed or anonymous, and the recipient isn't called ahead unless asked. Payment is by Visa or Mastercard, and the cart total is final.
For something other than one line of callas, other mono bouquets offer other flowers on the same idea, and mixed bouquets suit a gift that isn't meant to read as one shape.
