Not to be semantically confused with : Snow-in-Summer (Cerastium tomentosum) [a plant with similar name]
Frequently mis-named as:
Boissier's Glory-of-the-snow (Scilla luciliae) which has similarly pale-blue 'petals' which merge into white at the inner, but that usually has but 1 or 2 flowers (rather than 4-12 for Glory-of-the-Snow) and has longer 'petals' 12-20mm (as opposed to 10-15mm for Glory-of-the-snow).
Easily mistaken for :
Lesser Glory-of-the-Snow (Scilla sardensis) but the flowers are wholly bright-blue and with slightly more flowers, 6-16 as opposed to the 4-12 for Glory-of-the-Snow)
There are several other similar plants in both Scilla proper and in the former Chionodoxa genera that resemble Glory-of-the-Snow to various degrees.
No relation to :
Chilean Glory-flower (Eccremocarpus scaber),
Common Morning-glory (Ipomoea purpurea),
Crimson-glory-vine (Vitis coignetiae), Summer Snowflake (Leucojum aestivum), Snowdrop (Galanthus nivalis) or
Snowdon Lily (Gagea serotina) [plants with similar names belonging to differing families].
Glory-of-the-Snow is the most common of a series of differing Glory-of-the-Snows which are all introduced and naturalised plants grown in parks and gardens and grassy verges, from where it can spread or escape as garden throw-outs.
Glory-of-the-Snow is toxic to livestock and humans containing high quantities of
HomoIsoFlavonoids which have anti-bacterial, anti-mutagenic and anti-inflammatory properties. The HomoIsoFlavonoids found in Glory-of-the-Snow are as 3-Benzyl-4-Chromone, 3-Benzyl-3-Hydroxy-4-Chromanone and various variations on those as well as the
Scillascillin-type of HomoIsoFlavonoids.
As well as the Homo-Iso-Flavonoids shown here, Glory-of-the-Snow contains several others similar to these. However, this particular Scilla species has not been much studied for secondary metabolites.
The Scillascillen-type of Homo-Iso-Flavonoids are very unusual compounds for plants, containing a cyclo-butane ring (the square). The cyclo-butane ring is joined at a single point making these compounds spiro compounds. Many species of Scilla and other genera belonging to the same family (Asparagaceae) contain a great variety of slightly differing compounds with this 6,6,4,6,5-ringed skeleton. So many that your Author has not bothered to draw others and urges his readers to use their imagination.
