Agave geminiflora, commonly known as twin flower agave, can be an attractive addition to your garden when it blooms with large, pink flowers in the summer. The plant comes from Mexico and can grow up to 6 feet high, so make sure you’ve got room in your yard before investing in this plant.
The twin flower agave has become widely popular as an ornamental plant due to its colorful appearance and ease of cultivation in home gardens.
Agave geminiflora may be the most beautiful agave plant you’ve ever seen. It’s easy to grow and can be admired both indoors and out, but it’s not without its faults.
Origin and distribution
A native of southwestern Mexico, agave geminiflora is most widely cultivated in Tamaulipas state in northeastern Mexico. It thrives in warm weather, with optimum growing conditions occurring at altitudes of 1,000 to 1,500 meters (3,300 to 4,900 feet).
The twin flower agave requires full sun and well-drained soil for optimal growth. Its leaves are dark green on top and silvery gray underneath. Its flowers are white or pale yellow with a purple center. Its seeds are black when ripe.
This plant grows rapidly, typically reaching a height of 3 to 5 meters (10 to 16 feet) within three years. It has been used as an ornamental plant since 1789. The United States is its largest importer, followed by France and Japan.
Some parts of agave plants have been used for medicinal purposes since ancient times; however, these uses have not been confirmed by scientific studies.
Agave geminiflora propagation
Because propagation of agave is relatively simple, it is frequently propagated to create larger specimens. To propagate, plant one or more offsetting from a mature plant with a diameter of at least 12 cm in coarse sand and keep well watered.
New plants will develop around 6–12 months after planting. When they are 10–20 cm tall, they can be transplanted individually in pots or directly in the ground. It takes about five years for an agave to reach maturity. In cultivation, most species grow best in full sun and well-drained soil.
Water regularly during summer but avoid water-logging and let dry between watering. Protect from frost. In temperate regions, many species can be grown outdoors year-round; others must be kept as houseplants if temperatures drop below freezing.
If kept indoors, a minimum winter temperature of 5 °C is required. Most agaves need repotting every two to three years. Repotting should be done in early spring before new growth starts. Use pot with good drainage holes and gritty compost that drains quickly.
Agave geminiflora care information
Agave geminiflora is an easy-to-care-for houseplant. It will do well in a bright location but avoid direct sunlight. Keep soil evenly moist and fertilize monthly during the growing season with a water-soluble fertilizer diluted to half of its normal strength. If your agave is getting too big, it’s time to repot it into a container that’s one size larger than its current home.
Agave geminiflora can tolerate low light conditions. However, if you want it to reach a larger size then you should expose it to more light each day. In fact, if your plant is getting enough sunlight but hasn’t started growing in several months you may need to up its dose.
The best way to do that is by moving it closer to a window or even outdoors during the day so that it gets adequate exposure. Once acclimated and mature, agave can handle full sun with ease.
To successfully grow agave, you’ll need soil that drains well and does not stay wet for extended periods of time. A succulent potting mix that includes lots of sand is ideal for agaves because it mimics their natural habitat in Mexico. Never use regular garden soil when growing an agave, regular soil will not allow your plant to thrive!
If you have access to native soil from your area, try using about two parts native soil with one part sand or perlite. If you can’t find local native soil, look for a succulent potting mix at your local nursery or online.
Agave geminiflora is succulent, so it stores water in its fleshy leaves. However, it does require watering and should not be left to go dry for long periods of time. Water once a week during its active growth season, from March through September.
In the winter months, water less frequently, but do not let your plant go completely dry. If you have issues with over-watering or under-watering your plant, keep a log of how much water you provide to adjust accordingly for next time.
Give Agave geminiflora plant a little water and fertilizer. Be careful not to over-fertilize, as that could kill your plant. Use fertilizer sparingly, following instructions on labels for indoor or outdoor plants. If no instructions are given, use a quarter-strength mixture weekly during the growing season or every other week during winter.
Mix 1⁄4 teaspoon of 20-20-20 with 1 gallon of water and apply in the early morning after leaves dry from dew but before the sun has warmed leaves or soil. Water thoroughly after application; do not allow fertilizer to touch leaves.
Apply fertilizer only when the potting mix is dry, wait until you see new growth before fertilizing again. For best results, fertilizers should be mixed at half strength and applied once a month while plants are actively growing indoors or outdoors.
Agave geminiflora prefers hot, sunny locations with well-drained soil. The agave can withstand temperatures to -3°F (-19°C). In very cold climates, it is best to grow agaves in pots and move them indoors or to a greenhouse during winter.
Grow under glass in full sun. Exposure to too much direct sunlight may result in leaf burn, so keep young plants shaded for a few weeks after transplanting until they are acclimated.
When you choose an Agave geminiflora, be sure to pick one that is native to your climate. Agaves can survive in a variety of climates and if you don’t live in a desert, it might be hard to find one that will thrive in your area.
After all, succulents are drought-tolerant plants and don’t require much water at all. You also need to have plenty of sunlight exposure for optimal growth. Ideally, they should get 8 hours or more of sun every day!
The ideal humidity range is between 40 and 60 percent. If you live in a dry climate, then you might want to place your agave on a tray of pebbles and water.
This will help increase its humidity levels. On top of that, you can mist your agave with water every now and then to keep it hydrated. Make sure not to over-water it though! Agaves are also known for their ability to store water in their leaves so they don’t need as much watering as other plants do.
Although Agave geminiflora plants are extremely slow-growing and are considered one of the most difficult succulents to kill, it is still important to prune them regularly. They need to be cut back as soon as new growth appears in spring, at least every four years.
To prune an agave, use very sharp shears to remove any large leaves that get too big for their surroundings. For smaller or more delicate leaves, simply snap them off with your fingers.
If you plan on repotting your agave, wait until late summer or early fall when they’re fully dormant. At that time, you can also trim away some of its root mass if necessary.
When to repot
Repot your agave every three to five years. Some experts recommend repotting your agave every two to three years, but agaves have been known to live for decades in their original pots.
One factor that affects how often you’ll need to repot agave geminiflora is whether or not you’re using a container with drainage holes. In containers without drainage holes, water can remain trapped at the bottom of your pot, which can weaken your plant.
All agaves require dormancy, so they are not suitable for cold temperate or tropical regions, although some species can be kept inside in pots. All agaves need a dry period during winter when they lose their leaves and go dormant. The soil should be allowed to dry out completely; if there is still moisture it may lead to root rot.
In climates where winter temperatures fall below 10 degrees Celsius and nighttime temperatures are under 0 degrees Celsius, a ‘winter rest’ is essential. This means that watering must stop completely, but do not allow plants to become totally dry.
Covering with frost cloth will protect plants from low temperatures while allowing them to breathe. Watering can recommence as soon as new growth appears in spring. A very small number of species such as Agave victoriae-reginae (Queen Victoria agave) from Mexico have been known to survive outside without protection down to about -5 degrees Celsius for short periods of time.
Twin flower agave flower & fragrance
The large, tubular flowers of agave geminiflora open at night and smell a bit like apple blossoms. They are not particularly showy, but they’re highly fragrant and bloom in late spring and early summer.
Agave geminiflora, also known as two flowered agave or California century plant, has a very slow growth rate of 1 to 2 inches per year. Over a 30-year period, it can reach 6 feet in height and up to 8 feet wide.
However, many gardeners choose to keep it at a smaller size by cutting off its flowering stalk. This plant thrives in partial shade and is hardy in USDA zones 5 through 9.
All parts of Agave geminiflora are highly toxic due to multiple quaternary compounds such as agavin and homoaguavin. It is also a skin irritant and a respiratory system irritant. Though not deadly, it can be fatal to livestock animals that ingest large amounts. The toxicity varies by species, some being less harmful than others.
USDA hardiness zones
Agave geminiflora thrives best in USDA hardiness zones 9 through 11. If you live outside of these zones, you can still grow agave geminiflora, but it will be more difficult. In cooler climates, plant your agave geminiflora indoors during winter and move it outdoors once temperatures warm up in spring. In warmer climates, plant your agave directly into the soil as soon as possible after purchase.
Pests and diseases
The agave geminiflora is easy to grow, but it does have its share of pests and diseases. Some common ones include Giant mealybug, cochineal scale, citrus mealybug, red spider mite, grey mold, and leaf spot. If you notice your agave becoming sickly or not growing as quickly as usual, check it over for signs of disease or bugs.
Agave geminiflora is a beautiful and hardy succulent. It makes a great focal point in any desert landscape, with its unique twin-bloom head and bold foliage. If you are looking for something to place at your front door to welcome your guests, or want an eye-catching plant that will make your yard or patio come alive, look no further than agave geminiflora.
