A very easy way to differentiate would be size and shape of the bulbs, amaryllis bulbs are quite large about the size of a big onion and they are true bulbs, gladiolas are much smaller in size and are not true bulbs, they are corms, they are only covered by a couple of layers of a papery cover on top. Also the $$$$$$$$$$$ tells you everything, amaryllis bulbs are quite expensive, cheaper ones cost around 6-8 dollars per bulb and can go up to 20 dollars per bulb. Gladiolas are cheap, you can get 10 corms for about 4 dollars and even expensive ones cost less than 10 dollars per 10 corms.

Yes these shoots in your pic were from gladioli, no doubt, and double shoots are very very common and will increase your stock with time.

I like to show my detail photo of an emerging gardener's amaryllis;

Hippeastrum "RedPearl"; you can study very well the different way the leaves and flower stalks emerge from the BULB...

One could add that Hans-Werner's bulb has produced two bulbletts ( small "side-bulbs" ) that in time kan be planted out separately. So the leaves to the right and the left does not come from the "main-bulb".

Well,
Bergit;

on this veryvery opportunity - I simply can not let it pass un-used-ly:
I like to be a pedagoge, too, and you will immediately remember WHAT I want to say and what I recommended elsewhere, previously:

Do not deprive the kids of their mothers! Let them undisturbed-ly together and grow clusters with manymany flower stalks instead...

I wish you good gardening success,
regardless to gladioli or hippeastrums!

Your attention please = if your purpose is to have the greatest number of offsets (new bulbs) the fastest, then break the bulbils off your main bulb every August and plant them. If your purpose is to have more flowers sooner or to grow a large attached clump, then leave the bulbils (offsets) attached at least until they flower. Bill

Yes I think I can confirm this observation (I hesitate to generalize it on all cultivars).
The point for me is that I am not interested in multiplying a stock of one clone quickly - and I prefer clusters with big bulbs which emerge accordingly big and numerous stalks in one pot, in exhibition quality, for photo recordings only.

It seems as if the vulneration of the basal plate by breaking off the still closely attached bulbs induces or at least enhances the formation of new daughter bulbs.
