Can anyone please tell me what kind of plant this is? It has long and thin leaves and grows from a bulb. It looks like it's in the resting phase.
Given the size of the bulb, the position of the bulb in the pot (even with/above the soil level), the fact that two flowering stems came from the same bulb, and time of year (I'm assuming that the plant is in the Northern Hemisphere), I'd say that's an amaryllis (a cultivar in either the Hippeastrum or Amaryllis genera). If I were a betting man, I'd bet on it being a Hippeastrum. The bulb position and arrangement of the leaves rules out clivia, and the fact that it has leaves after flowering tends to rule out any plant in the Lycoris genus.
It looks like a pregnant onion or Ornithogalum caudatum.
Amaryllis or hippeastrum ?, after reading Wikipedia I don't know any more. The difference may be when it bloomed , Amaryllis blooms in winter in northern hemisphere ; IF it has had months ( 4 +) of dry dormancy. I think I have very large hippeastrum in the ground that bloom May/June (US zone 8) . Natural dormancy works fine. The blooms are similar to amaryllis. I can promise you,an amaryllis left in the ground here is 90% unlikely to re -bloom. The first of August I put my amaryllis pots in a green house- sun but NO water . I expect blooms in the winter. My guess , you have a modest size amaryllis that might big enough to bloom if you give it no water . It will slowly go dormant and ,if lucky, a green bud will show next winter.
