Hi - today is Wednesday 5th August 2015.
Just read the above and as a veg gardener who grows both Standard garlic and Elephant garlic I have observed that my Elephant garlic stores better than my normal garlic. I was still eating the crop I had sown back in September 2013 and harvested June 2014 up until July this year when the new crop was harvested and seasoned - I lift the garlic and leave all the leaves on while they dry with the leaves becoming very brittle (this tells me they are cured and ready for storage) - I then cut the stalks off leaving about four inches and store in open cardboard produce trays in my frost free shed. The bulbs need to have free flowing air around them - placing them in the fridge/plastic bag/warm indoor room will reduce greatly the storage ability of the Elephant garlic.
The standard garlic I grow is the Purple Wight soft neck garlic and perhaps a different variety would store better - such as a hard neck variety (Elephant garlic is hard neck). The difference is a soft neck does not throw up flower spikes (Scapes) which should be broken off to prevent flowering and growth energy going into flower and seed production rather than bulking up the cloves.
I agree on the milder flavour and differing use - for me Elephant garlic is a vegetable to roast whole, slice, chop or roughly crush into soups, stews, stir fry's, curries etc. while true garlic is a herb or seasoning ingredient which I always use if the recipe states "rub with garlic" or "add two crushed cloves of garlic" but for garlic chicken - I stuff with elephant garlic and the then soft large cooked cloves can be eaten (if you like garlic a lot :0) )
