WaterFor Wallflower, or Erysimum × marshallii, it's crucial to water it deeply but infrequently, to promote strong root growth. Aim to water this plant with about 1-2 gallons every week during the growing season, depending on the weather and soil conditions – more frequent watering may be necessary during prolonged dry spells or extreme heat. During the winter, reduce watering but do not let the soil completely dry out. Always check the top inch of the soil; if it's dry, it's time to water. Overwatering can lead to root rot, so ensure good drainage and avoid letting the plant sit in waterlogged soil.
LightWallflower thrives in full sun, meaning at least 6 hours of direct sunlight daily. The ideal spot for Erysimum × marshallii is in a location where it can receive unfiltered sunlight throughout most of the day. This plant can handle a little partial shade, especially in hot climates, but too much shade can lead to leggy growth and fewer flowers.
TemperatureWallflower prefers a temperature range typical of temperate climates, thriving best when the daytime temperatures are between 60 and 75 degrees Fahrenheit. It can survive minimum temperatures down to about 20 degrees Fahrenheit, but it's important to protect it from harsh frosts. Maximum temperatures should ideally stay below 85 degrees Fahrenheit, as extreme heat can stress the plant.
PruningPruning Wallflower is important to encourage bushier growth and more blooms. Trim back spent flowers regularly to promote continued blooming. In early spring or late winter, prune back the old growth by about one-third to help rejuvenate the plant. It's best to prune after the last frost but before the new growth starts.

Life cycleErysimum × marshallii, commonly known as Wallflower, begins its life cycle as a seed, which requires a well-drained soil and full sun exposure to germinate. Upon germination, it develops a root system and foliage as a juvenile plant, growing rapidly in favorable conditions. As it matures, the Wallflower enters the flowering stage, producing vibrant flowers, often in shades of yellow, orange, or red, which attract pollinators for sexual reproduction. Following pollination, the plant develops seed pods, and once matured, the seeds are dispersed by wind, gravity, or animal activity, completing the reproductive cycle. The Wallflower is a perennial, capable of surviving through multiple seasons, with some species having the ability to live several years, and it can spread through self-sowing if the conditions are suitable. As a perennial, the plant may enter a period of dormancy during adverse conditions, such as cold winter months, only to resume growth with the return of favorable weather.
PropogationPropogation time
Spring to Summer
Propogation: Erysimum × marshallii, commonly known as Wallflower, is frequently propagated through seed sowing. The ideal time for sowing Wallflower seeds is typically in late spring or early summer, after the threat of frost has passed. To propagate by sowing, seeds should be lightly pressed into the soil surface or covered with a thin layer of soil and kept moist until germination, which usually takes 14-21 days. Once the seedlings develop true leaves and are sturdy enough to handle, they can be thinned and transplanted to their final positions in the garden. This method is favored for its simplicity and effectiveness in producing new plants that are true to the parent's characteristics.
