Q.My Clivia Has Produced Blossoms But No Stem
The flowers are “stuck”low in between the leaves. The stem they should be on never formed. Otherwise happy and healthy.

Some species do not have elongated stems. This is indicative of a specimen closer to a wild specimen than the modern ones. This could mean that the plant this came from was grown from a cross pollinated seed, or that it is, simply, one of the short-stemmed types.
You can try a few things, though.
After testing your soil for deficiencies, you can add a little potassium and phosphorus to the soil. This can help with stem and bloom formation.
You can try decreasing the amount of light that the plant receives. This can force stem elongation in response to a slight lack of light.
Other than this, you may be stuck with a low flowering type.
