Do wallflowers grow back in the spring from the original plant (do you cut it back or do they just reseed themselves)?
Here is more information on growing wallflower plants: https://www.gardeningknowhow.com/ornamental/flowers/wallflower/growing-wallflower-plants.htm
The Wallflower is an old-fashioned garden flower which, although a perennial is usually grown as an annual or biennial because it tends to 'bloom itself to death'.
This 12"-24" plant produces a profusion of fragrant, brightly colored flowers all spring making it an excellent choice for your butterfly garden, flower bed, or garden border.
Now they are finished. Can I leave them in, though they look untidy, or can I cut them back? If I do this, will they return next year?
Deadhead the flowers after flowering. The foliage can be attractive after the flowers have bloomed.
Wallflower can be grown as a perennial in warmer climates.

Do wallflowers bear flowers from 1st season? I had sown seeds in mid October and transplanted in mid November in 8" container trays. They are almost 1 ft tall and very healthy but not yet bloomed. It is end of January now. When should I expect them to bloom? I live in western part of India and temp right now is high of 30 and low of 15*C. Thank you, Tanvi
Wallflowers have a two-year cycle, when grown from seed, and will grow only leaves the first year and then bear flowers the 2nd year.
Does anyone have details on this? Where do I cut the cutting on the plant? Do you just put it in the soil or do you have to place in water to start the roots growing on the cutting before planting? Is spring the right time to do this?
They root best as small side shoots. Pull from the plant with a small 'heel' attached.
Trim up the 'heel' so there are no strips of bark attached and remove the lower leaves.
Insert 1/3 of the cutting in a pot mixture of compost and perlite and keep moist in a well lit and well ventilated unheated location.
They can be planted out the following spring.
Take plenty of cuttings as the success rate can be low.
I have got wallflowers that have long stems with just one bloom at its tip
Two things come to mind:
This can happen when there is not enough nutrients in the soil, or an excessive amount of nitrogen, but not enough potassium and phosphorus.
This can also happen when there isn't quite enough sun, so be sure that these receive more sun than shade, if they are in a shaded location.

My first wallflower plant. My question is, there are only a few buds now on the very top of the spikes, the rest of the stem is bare. Do I leave the stems alone all summer, or cut them back?
It's important to pinch the flowers back on this plant to keep it blooming. Here are two articles that will be helpful:
am i over watering or do they need potting on from individual cells.
Unfortunately, your photo did not come through. I cannot say with certainty. Usually browning will be due to overwatering, but can be due to lack of nutrients, too much nutrients, too much sun, and crowding, depending on, exactly, how it appears.
