Plant Overview
Often called the Winged Greenweed or Winged Broom, this low-growing European native is a master of structural disguise. Its unique, flattened stems look like vibrant green ribbons or flight vanes, helping it survive in harsh, windswept environments where traditional leaves might wither. It is a favorite for rock gardens, where it creates a sprawling, golden carpet of pea-like blooms during the transition from spring to summer.
🔍 How to Identify
- 🌿 Winged Stems: The most striking feature—its branches are broadly flattened and "winged" with green tissue, which actually performs most of the plant's photosynthesis.
- 🌼 Pea-Shaped Blooms: Dense clusters of bright, lemon-yellow flowers emerge at the ends of the branches, standing upright like small golden torches.
- 🍃 Minimal Foliage: The actual leaves are tiny, hairy, and oval-shaped. They are often sparse or fall off early, leaving the architectural green stems to define the plant's look.
🏡 In Your Garden
- 🪨 Rocky Resilience: This plant thrives in poor, sandy, or stony soils where other plants struggle. It is an excellent choice for stabilizing sunny slopes or filling gaps in dry rockeries.
- 🚫 Deep Taproot: Like many members of the broom family, it develops a deep root system very quickly. It strongly dislikes being moved once established, so choose its permanent "forever home" with care.
- 🌱 Soil Improver: As a legume, it has a symbiotic relationship with soil bacteria that allows it to "fix" nitrogen, effectively fertilizing the soil for surrounding plants over time.
⚠️ Safety & Toxicity
- 🚫 Toxic Status: All parts of the Winged Greenweed are toxic if ingested.
- 🤢 The Risk: The plant contains quinolizidine alkaloids (such as cytisine). If eaten by pets or humans, it can cause nausea, vomiting, dizziness, and in large quantities, more serious heart and respiratory issues. It is best handled with gloves if you have sensitive skin, as the sap can occasionally cause mild irritation.
✨ Fun Fact
👑 Royal Roots: The genus name Genista is the linguistic origin of the "Plantagenet" royal dynasty of England. Count Geoffrey of Anjou famously wore a sprig of broom (Planta genista) in his hat, eventually giving his name to a line of kings that included Richard the Lionheart and Edward III.

To successfully grow Genista Sagittalis (also known as Arrow Broom) plants, you can follow these steps:
- Choose the right location: Genista Sagittalis prefers full sun to partial shade. Select a spot in your garden that receives at least 6-8 hours of direct sunlight per day.
- Prepare the soil: Make sure the soil is well-draining and of average fertility. If your soil is heavy or clayey, mix in some organic matter like compost to improve its drainage and nutrient content.
- Planting: Dig a hole that is as deep and wide as the plant's root ball. Gently remove the plant from its container and place it in the hole. Backfill the hole with soil, ensuring that the plant is level with or slightly above the surrounding soil. Lightly tamp down the soil around the plant to remove any air pockets.
- Watering: Water the plant thoroughly after planting and keep the soil consistently moist but not waterlogged. Once the plant establishes, it will be more drought-tolerant, but regular watering during dry periods is beneficial.
- Mulching: Apply a layer of organic mulch around the base of the plant, such as wood chips or straw, to help conserve moisture and suppress weed growth.
- Pruning: Genista Sagittalis generally does not require much pruning. However, you can trim back any dead, damaged, or overcrowded branches in early spring to promote healthy growth and maintain an attractive shape.
- Fertilizing: You can apply a slow-release granular fertilizer formulated for flowering shrubs in early spring. Follow the manufacturer's instructions for the appropriate amount to use.
- Pests and diseases: Genista Sagittalis is relatively resistant to pests and diseases. However, keep an eye out for aphids or spider mites. If infestations occur, treat them with an appropriate insecticidal soap or organic pest control method.
- Winter protection: In colder regions, cover the plant with a layer of mulch or straw in late fall to protect it from freezing temperatures.
By following these guidelines, you should be able to grow a healthy and beautiful Genista Sagittalis plant in your garden.
Place in a bright room that is sun drenched almost all day. Or directly in a south-facing window.
To properly water this particular plant, it is important to consider the amount of sunlight it receives and the condition of the soil. Before watering, it is recommended to check the soil moisture level by inserting a finger or a wooden stick into the soil. If the soil feels dry to the touch, it is time to water.
When watering, it is best to use a watering can or hose with a gentle stream to avoid damaging the plant. Water should be applied directly to the soil at the base of the plant, avoiding the foliage as much as possible. Water should be applied until the soil is moist but not waterlogged.
It is important to note that overwatering can be harmful to the plant, causing root rot and other issues. Therefore, it is recommended to wait until the soil has dried out slightly before watering again. Additionally, during periods of drought or extreme heat, the plant may require more frequent watering to ensure it stays healthy.
To fertilize the Genista Sagittalis plant, apply a balanced NPK fertilizer during the growing season. Use a slow-release fertilizer to avoid over-fertilization. Apply the fertilizer according to the instructions on the packaging. Water the plant well after fertilization. Avoid fertilizing during periods of dormancy or when the soil is dry.
The ideal soil for planting the Genista Sagittalis plant should be well-draining and fertile. It should have a pH level between 6.0 and 7.5. The soil texture should be sandy or loamy to allow for good aeration and water movement. Adding organic matter, such as compost, can help improve the soil's fertility and moisture-retention capacity. The plant prefers soil that is moist but not waterlogged, so it is important to ensure proper drainage. Avoid using heavy clay soils that retain moisture for long periods. The Genista Sagittalis plant is also tolerant of acidic soils, so mixing in some acidic fertilizers, such as pine needles or peat moss, can help if the soil is too alkaline.
To propagate this plant, you can take softwood cuttings from new growth in the spring or early summer. Cut a 4-6 inch stem just below a leaf node and remove the leaves from the bottom half of the stem. Dip the cut end of the stem in rooting hormone and plant it in a container filled with a well-draining potting mix. Keep the soil moist and in a warm, bright location but out of direct sunlight. The cutting should root within a few weeks. Once it has developed a strong root system, it can be transplanted into a larger container or into the garden. Alternatively, you can propagate this plant from seed sown in the fall or early spring. Sow the seeds in a well-draining potting mix and keep them moist in a warm, bright location. The seeds should germinate within a few weeks and can be transplanted into larger containers or into the garden once they have developed a strong root system.
