2 of my Streptocarpus are not flowering.

[I like streps]

Hi, I have two Streptocarpus that are not flowering. I treat them like the others. That is that I fertilize them and water them every week. They are in a kitchen that has a medium amount of light.

What could I do to make these 2 Streptocarpus flower?

My first thought would be they need more light either in intensity or duration. Possibly both.

I agree with Xena that it is a light intensity or duration problem. Those two particular streps are probably genetically programmed to need more light. Just because all your streps are treated alike, it doesn't mean they will react the same. Keep in mind that depending on the ancestry of a particular strep, it will act differently. For example, some streps that have parents or grandparents that are species just might bloom heavier during certain seasons. Some streps prefer to dry out a little more than others. Some don't like to dry out even for a minute. Some like way more light than others because in nature their particular ancestor grew out in the sunlight rather in shade.

To further illustrate my comments, take a look at Ron Myhr's Gesneriad Reference Web site at:
http://www.gesneriads.ca/strep%20298.htm

That shows S. dunnii facing the sun on a hillside. If you had S. dunnii with your other streps, it probably wouldn't bloom because it would not get enough light. Also, the hybrids using S. dunnii as a parent or grandparent would need more light, too. An example is 'Dale's Scarlet Macaw' which is a cross between Texas Hot Chili x S. dunnii. I grow it on a plant stand under 4 fluorescent tubes which gives 12 hours of light. It is blooming quite strongly.

The Gesneriad Society has an International Registry which shows the parents of registered gesneriads at: http://gesneriadsociety.org Scroll down on the right side to find the International Registry. Sometimes you'll be able to see a photo of the strep, depending on when it was registered and whether the hybridizer sent a photo.

We can't always find out the ancestry of our streps, so my suggestion is: if a plant is not cooperating and after 6 months you can't figure out what it needs, or you can't accommodate its needs for more hours of light or increase the intensity of the light, then don't waste plant space. Sell, trade or give it away and try a different strep.

I would never get rid of my Streps since some of them are 20 years old. I love them.

But, I will read the info you gave me.

Thanks.

Another option is to share leaves with someone who grows under tube lights and will promise to send you photos of the plants in flower.
