I have a clivia plant that is several years old. It has bloomed for me in the past, but this year (and last) flower buds formed deep inside the
It sounds like your clivia is suffering from the cold! They prefer temperatures that don't go below 60-65. Fertilize them lightly in the spring and summer with a fertilizer that has a high middle number. Let them dry out completely in the late fall into the winter, but keep the minimum temperature. When you begin to see the bud form resume light watering (no fertilizer) and keep the temperature between 65 and 70. Also, after the flower dies, remove the bloom stalk completely. Also I find they don't like to be moved to a different location until the bloom stalk has reached its full height.
