Cheeseman recorded Gladiolus in T.N.Z.I. 15, 1883, 293 as " . . . a frequent garden escape" and Allan (Handbk Nat. Fl. N.Z. 1940, 305) notes "Various garden gladioli escape".
Gladiolus byzantinus Miller, a European sp. which has reddish-purple flowers with a narrow white mark on the lower perianth-lobe, was recorded by Kirk for the Waikato district (T.N.Z.I.2. 1870. 143) but no specimens have been seen.
Large-flowered, modern hybrid gladioli are discarded from gardens from time to time and may persist in waste places e.g.CHR 196636, Broadfields, Canterbury, waste land - site of closed rubbish pit, A. J. Healy 69/306, 14.3.1969. Other specimens collected growing wild which have red flowers with white marking on the lower lobes may be G. × cardinalis hybrids e.g.CHR 74094, Bolton St Cemetery, Wellington, grass, R. Mason 1470, 9.12.1952; andCHR 276321, Mission Station, Waimate North, Bay of Islands Co., in grassy area beside church, S. J. and E. J. Astridge, 27.11.1974.
