Spanish broom Spartium junceum
ABOUT
The plant commonly known as Spanish broom is a highly recognizable Mediterranian native with a very distinctive appearance. Its green stems are slender, round, and leafless, giving the plant a reed-like appearance. During the growing season, though, it does produce small, sparse leaves that are blade-shaped and quickly shed. Spanish broom is renowned for its bright yellow, pea-like flowers that bloom profusely and emit a sweet, intoxicating fragrance. These blossoms are arranged in loose clusters at the stem tips, creating a vibrant contrast against the green stems. Following the flowering period, the plant produces seed pods that are hairy at first but become smooth as they mature. These pods eventually turn blackish-brown and may persist on the plant throughout the winter. The overall form of the Spanish broom is upright and slightly arching, presenting a bushy demeanor, despite most of its photosynthesis being carried out by its green stems due to the scarcity of its leaves. Its sparse foliage combined with the abundant, colorful flowers makes it a popular choice for decorative purposes in landscapes.

- Toxicity
To humans
Spanish broom (Spartium junceum) contains toxic alkaloids, including sparteine and sarothamnus, that can affect the human body if ingested. Consumption of any part of the Spanish broom plant can lead to symptoms such as nausea, vomiting, diarrhea, abdominal pain, dizziness, tachycardia (rapid heartbeat), and potentially convulsions. In severe cases, it can also cause respiratory failure which could be fatal.
To pets
Spanish broom is also toxic to pets due to the same alkaloids – sparteine and sarothamnus. If pets ingest parts of the Spanish broom plant, they may present with signs of poisoning such as vomiting, diarrhea, weakness, and lethargy. In severe cases, it may cause changes in heart rhythm, convulsions, and potentially death.

- Water
The Spanish broom (Spartium junceum) is a drought-tolerant plant that requires only minimal watering once established. Young plants should be watered deeply and infrequently to encourage a strong, deep root system, typically this means every couple of weeks depending on the weather. Once established, these plants can survive with natural rainfall, but during prolonged dry spells, a deep watering every 4 to 6 weeks is beneficial. Avoid overwatering, as Spanish broom does not tolerate soggy soil. When you water, aim for about 1 to 2 gallons per plant, ensuring you wet the soil thoroughly to reach the root zone.
- Light
Spanish broom thrives in full sun conditions, requiring at least 6 to 8 hours of direct sunlight daily. Place the plant in a location where it will receive unfiltered sunlight throughout the day for optimal growth and flower production. Avoid shaded areas as insufficient light can result in a leggy plant with poor flowering.
- Temperature
Spanish broom is tolerant of a wide range of temperatures but prefers a warmer climate. Ideal temperatures for Spanish broom fall within the range of 60°F to 80°F but the plant is hardy and can withstand temperatures as low as 10°F and high up to around 100°F. Ensure to protect young plants from frost to prevent damage.
- Pruning
Prune Spanish broom to maintain its shape, promote denser growth, and enhance its flowering ability. The best time for pruning is in late winter or early spring, just before new growth commences. Pruning can be done annually or biannually depending on the desired size and shape of the plant. Remove any dead or diseased branches, and cut back old growth to encourage fresh blooms.
- Cleaning
Not needed
- Soil
The Spanish Broom (Spartium junceum) thrives in well-draining soil with a pH range of 6.0 to 7.5. A mix of sandy loam or gravel and compost is ideal, ensuring optimal drainage and aeration.
- Repotting
Spanish Broom typically does not require frequent repotting. It can be repotted every 2-3 years to refresh the soil or when it outgrows its current pot.
- Humidity & Misting
Spanish Broom prefers low to moderate humidity levels and can withstand dry conditions; therefore, it does not have strict humidity requirements.
- Suitable locations
Indoor
Place Spanish Broom in bright light indoors.
Outdoor
Plant in full sun and well-drained soil outdoors.

- Life cycle
Spartium junceum, commonly known as Spanish broom, begins its life as a seed, which germinates in the spring when soil temperatures rise and moisture is adequate. The seedling emerges and establishes a root system, followed by rapid stem and leaf growth during the first growing season. As a perennial shrub, it enters a vegetative stage where it focuses on growth and development of its woody framework and foliage. After one or more years, when mature enough, it starts producing bright yellow, pea-like flowers, typically during late spring to early summer. Once pollinated, these flowers develop into pods containing seeds that mature by the end of summer. The plant then enters a period of dormancy during colder months, although in milder climates, it may retain some leaves, and with the return of favorable conditions, the cycle resumes with new seed germination or growth from the existing rootstock.
- Propogation
Propogation time
Spring-Early Summer
Propogation: The most popular method of propagation for the Spanish Broom (Spartium junceum) is through its seeds. The best time to propagate by seeds is generally in the spring after the danger of frost has passed, which allows the seedlings to establish themselves during the warmer months. To propagate Spanish Broom, seeds should first be scarified, which means slightly damaging their hard outer coating to encourage germination. This can often be achieved by gently rubbing the seeds with sandpaper or nicking them with a knife. After scarification, the seeds should be soaked in warm water (approximately 104 degrees Fahrenheit or 40 degrees Celsius) for 24 hours to further enhance germination rates. Once prepared, the seeds are sown in well-draining soil and lightly covered. They should be kept moist until germination, which often occurs within one to two weeks.
