My Torenia appears to wilt and feels a bit tacky.
It is likely being affected by insect pests - perhaps aphids or another sap-sucking insect. The stickiness is from the honeydew these pests leave behind. I recommend treating the plant with Neem oil, which will help take care of these pests and many others. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm

I planted this in a shaded area and it looks beautiful but is not flowering.
Torenia plants like moist but well-draining soil and they do best in morning sun and afternoon shade. Double-check your location and water situation and think about fertilizing soon. This article may help you:

I got a plant as a gift, and I don't what it is. I have tried google image search as well. Can anyone help me figure it out, so I can search for the care guide for my plant.

The buds on my wishbone plant are not blossoming. There are some white spots on the leaves as well.
Torenia is prone to powdery mildew and root rot. The plant prefers consistently damp but not soggy soil and part shade. If your plant hasn't been repotted in the past 3 months, start with repotting and going up one pot size. Don't use potting mix with added fertilizer which is formulated for outdoor summer plants. Assess the roots for rot and adjust your watering practices as needed. Use a balanced fertilizer such as 10-10-10 at half the recommended rate. If your plant seems to be recovering but still not blooming, consider supplemental light.
Can you tell me if the plant is toxic to animals?
I cannot find any indication that it is toxic at all, but it will be best to err on the side of caution when it comes to this subject. Just do what you can to keep houseplants out of their reach. If it is outside, then this can be hard to do, but I could not find any sources indicating that this could harm animals.
This is for a 24" Balcony Rail planter, with burlap liner approximately 7" deep.
