What a frustrating dilemma! You purchased a beautiful, healthy plant anticipating the gorgeous blooms in your landscape. You carefully plant it in the perfect location; you water it just enough; you fertilize it and protect it from bugs and diseases. Three years later the plant has grown beautifully. The foliage is lush and deep green…but no blooms! Let’s take a look at the possible problems.

Maturity

First of all, what is the purpose of a flower? Flowers are the reproductive parts of the plant. Their colors, shapes, fragrances and even timing are all part of the plan. As with all other living things, plants must reach a particular level of maturity in order to reproduce, and so this may be a reason for not flowering…it could be a bit too young. An extreme example would be the century plant which may live thirty years only to flower once, signifying the end of it’s life.

Pruning

Another issue that has a direct effect on flowering is pruning. Plenty of folks believe that their plant won’t flower unless it is pruned, but consider this: did that type of plant not flower before there was someone around to prune it? The fact is that pruning is often more beneficial to the owner than the plant. By removing dead or unproductive parts, reducing the overall size of the plant, eliminating competition between two plants in close proximity, and even “dead-heading” or removing old blooms, pruning has more to do with our wishes for the plant than for the plant’s ability to produce flowers. In fact, pruning incorrectly or at the wrong time of year can remove what would otherwise have been flowers.

Growing conditions

The next issue effecting flowering includes several aspects I’ll lump together under “growing conditions”. Plants that prefer “full to part sun” may not flower if planted in less than a couple of hours of direct sunlight. If the soil is too wet or too dry, that will effect flowering as well as overall health of the plant. Using a fertilizer with too much nitrogen can stimulate lush green growth at the expense of flowers…this is an especially prevalent concern with enthusiastic novice vegetable gardeners.

Have a rhoddie with very nice foliage and has grown more than triple in size over about 10 years --- but it has never bloomed. Planted within a few feet of another rhoddie which is loaded with blooms every year! I even talk to the non-productive one, but it just doesn't listen!

The leaf looks like a nasturtium. They like poor soil and lots of sun
