ToxicityTo humans
The shrubby scorpion vetch (Coronilla valentina subsp. glauca 'Variegata') is known to be toxic if ingested. In humans, the consumption of any part of this plant can lead to various symptoms, which may include vomiting, diarrhea, abdominal pain, and in severe cases, respiratory difficulties or cardiac complications.

WaterThe variegated scorpion vetch should be watered regularly during its growing season, roughly once a week, providing enough water to moisten the soil thoroughly, which could be around half a gallon for a medium-sized pot. Ensure the soil has adequate drainage to prevent waterlogging. Reduce watering in the winter months to every two to three weeks, just enough to prevent the soil from completely drying out.
LightVariegated scorpion vetch thrives best in full sunlight to partial shade. Place it in a spot where it can receive at least six to eight hours of direct sunlight daily. However, in extremely hot climates, some afternoon shade will help prevent leaf scorch.
TemperatureThe variegated scorpion vetch prefers temperatures between 50°F and 80°F. It can survive minimum temperatures of around 30°F but should be protected from frost. To assure optimal growth, keep it away from drafts and sudden temperature changes.
PruningPrune the variegated scorpion vetch to shape it, remove any dead or damaged branches, and promote denser foliage. This is best done in the early spring before new growth begins. Light pruning can also be done throughout the growing season to maintain the plant's shape.
CleaningAs needed
SoilVariegated coronilla thrives in well-draining, loamy to sandy soil enriched with organic matter. The best soil pH range for this plant is between 6.0 and 7.5. A balanced soil mix can be created by combining two parts loam, one part sand or perlite, and one part compost or peat moss.
RepottingVariegated coronilla should be repotted every two to three years to refresh the soil and to accommodate the growth of the plant. It's best to repot in the spring season before new growth begins.
Humidity & MistingVariegated coronilla prefers moderate humidity levels but is adaptable to the humidity levels found in most home environments. It doesn't require high humidity and too much can lead to fungal issues.
Suitable locationsIndoor
For indoors, provide bright, indirect light and avoid overwatering.
Outdoor
Place in full sun to partial shade and protect from strong winds.

Life cycleCoronilla valentina subsp. glauca 'Variegata', commonly known as variegated shrubby scorpion vetch, starts its life cycle as a seed, which, under appropriate conditions of soil, temperature, and moisture, will germinate and sprout. The seedling grows into a young plant with characteristic green and cream variegated leaves, and as it matures, it develops a woody stem and foliage in a bushy habit. During its flowering stage, typically in spring and sometimes into summer, it produces clusters of fragrant yellow flowers attractive to bees and other pollinators. Following pollination, the plant may produce seed pods, which eventually dry and release seeds to propagate the next generation. The variegated shrubby scorpion vetch is a perennial plant, thus it will enter a period of dormancy during the colder months, only to resume growth and repeat the flowering cycle in subsequent years. As a long-lived perennial, it continues this cycle for many years, growing larger and more established with each passing season until it reaches the end of its natural lifespan.
PropogationPropogation time
Spring to early summer
One popular method of propagating Coronilla valentina subsp. glauca 'Variegata', commonly known as Variegated Scorpion Vetch, is by semi-ripe cuttings. This is typically done in the late summer. To start, select a healthy stem with recent growth and cut a piece around 4 to 6 inches (10 to 15 cm) in length, making sure it includes at least one set of leaves. Strip the lower leaves and dip the cut end into rooting hormone to encourage root development. Plant the cutting into a well-draining potting mix and cover with a clear plastic bag to retain humidity. Place the pot in a warm, bright area out of direct sunlight, ensuring that the soil remains moist but not waterlogged. Roots will generally form in a few weeks, after which the plant can be gradually acclimated to normal conditions and eventually transplanted outdoors if desired.
