Red List (1989) :

This species has a threatened status and is listed in the Red Data Book of the Maltese Islands

Flowering Time :

Jun-Aug

Colour of Flowers:

Red or Violet

Habitat :

Arid rocky places and exposed garigue

Remarks :

The species Allium amethystinum Tausch which is also reported from same habitat and localities is likely a misidentification for Allium sphaerocephalon. Further investigation is required to verify this or the improbable possibility of having both. The populations flowering in July with small wine-red inflorecences, growing in arid exposed garigue most in the north and northwest of Malta have been also ascribed to Allium amethystinum but from a careful inspection of some specimens, they were identified by Stephen Mifsud as Allium sphaerocephalon subsp. sphaerocephalon. Both species are morphologically similar. The subspecies arvense which is larger, have white to green flowers and mostly occurs on the south and west coast of Gozo was reported for the first time by Michael Briffa in the late nineties. The plants growing in Malta appear to be particularly smaller and further investigation may reveal interesting findings.
