I planted Red Hot pokers last Autumn. No flowers this year, only green leaves
Soil is good; I planted Alliums at the same time and they have been fantastic.

I'm not familiar with the climate of your country, but the most usual suspects for these not to flower correctly is cool temperatures that never get particularly warm, or wet soils. They don't like wet soil one bit, so proper drainage is important.
There is also a possibility that the soil lacks phosphorus and potassium, or has too much nitrogen present. This can cause a lack of flowers, too, but if the Allium are doing fine, then this is less likely.
