Propagation of Whale’s Tongue Agave
Propagating whale’s tongue agave (Agave ovatifolia) can be done through two methods: seed propagation and bulbil propagation. Both methods are simple and effective ways to create new plants and expand your collection of these stunning succulents.
To propagate whale’s tongue agave from seeds, start by collecting mature seeds from a healthy plant. Sow the seeds in early spring when the temperature ranges from 55-70°F. Fill a seed tray or small pots with a well-draining cactus mix, and lightly press the seeds onto the surface of the soil, ensuring they are in contact with the soil. Mist the surface with water to moisten the seeds, and cover the tray or pots with a plastic dome or wrap to create a greenhouse-like environment. Place the tray or pots in a bright, warm location, and maintain consistent moisture by misting when the soil feels dry. Germination typically occurs within a few weeks to a couple of months. Once the seedlings have developed several sets of true leaves, they can be transplanted into individual pots or directly into the garden.
Whale’s tongue agave produces bulbils, which are small plantlets that grow along the inflorescence or flowering stem. These bulbils can be used to propagate new plants. To propagate from bulbils, wait until they are fully formed and firm, usually after the parent plant has flowered. Gently remove the bulbils from the stem, making sure they have a small piece of the stem attached. Prepare a well-draining potting mix, and plant the bulbils directly into the soil, burying them about halfway. Water lightly, and place the pot in a bright location with indirect sunlight. Maintain slightly moist soil, and after a few weeks, the bulbils will establish roots and begin to grow. Once they have developed a strong root system and several sets of leaves, they can be transplanted into individual pots or directly into the garden.
Growth and Development of Whale’s Tongue Agave
Whale’s tongue agave, also known as Agave ovatifolia, is a slow-growing plant that undergoes a fascinating process of growth and development. It takes about 10 years for this succulent to reach maturity and flower. Once it does, it produces magnificent flowering spikes that can reach impressive heights of 12-15 feet. These spikes are adorned with dense clusters of greenish-white flowers, adding a touch of elegance to the garden.
During its growth, the rosette of whale’s tongue agave expands, with the leaves developing their distinctive blue-gray coloration. The leaves are cupped and have a textured surface, giving the plant a sculptural appearance. Along the margins of the leaves, you’ll find small teeth, while the tip is adorned with a dark gray spine.
