Since these are two very different plants that did not bloom, I suspect that you have an issue with phosphorus in your soil. Plants need phosphorus to bloom. Here is more information on that:

Have your soil tested to determine what is causing the phosphorus deficiency. You can also add bone meal (https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/bone-meal-fertilizer.htm) to the soil to add phosphorus.
