ABOUT
Asphodeline liburnica, commonly known among gardeners as Jacob's Rod, is an eye-catching perennial plant. Its overall form is upright and spiky, creating a strong vertical element in the landscape. The foliage of Jacob's Rod consists of a clump of narrow, dark green, grass-like leaves, which are somewhat fleshy and often have a blue-green hue. These leaves give the plant a tufted look at the base. As spring turns to summer, Jacob's Rod produces tall, spike-like flower stalks. The blossoms arrayed along these stalks are star-shaped, typically bright yellow, sometimes with a greenish tinge, and have a slightly waxy appearance. They bloom progressively from the bottom up, creating a lengthy display of color. When the plant is not in flower, its striking foliage serves as an elegant and textural backdrop in the garden. After flowering, Jacob's Rod develops brown, three-sided seed capsules, which also have ornamental value. In addition to these striking visual features, the plant can also be recognized by its dry habitat preference and its affinity for sunny locations. Overall, Jacob's Rod adds a burst of bright color and an exotic look wherever it is planted.

Water
Jacob's Rod, also known as Asphodeline liburnica, prefers moderate watering. It should be watered deeply when the top inch of the soil feels dry. This may translate to watering approximately once a week, but always check soil moisture before watering. The amount of water required may vary, but generally, it will need around 1 gallon per week during active growth periods. It is important to avoid overwatering to prevent root rot, particularly during the dormant winter months when it may require less frequent watering.
Light
Jacob's Rod thrives in full sun conditions where it can receive at least 6 to 8 hours of direct sunlight a day. The best spot for this plant is in a location where it's exposed to unfiltered sunlight for most of the day. Avoid placing it in deep shade or an overly dark area, as insufficient light can impede its growth and flowering.
Temperature
Jacob's Rod does well in a wide range of temperatures but prefers to be kept in an environment that stays within 50°F to 80°F for optimal growth. It is cold hardy and can tolerate temperatures down to around 0°F, making it suitable for gardens in various climates. Avoid exposing the plant to prolonged periods of temperatures above 80°F, as high heat may stress the plant, especially if humidity is also high.
Pruning
Jacob's Rod should be pruned to remove spent flower stalks after blooming and to tidy up any dead or damaged foliage. This is typically done in late fall or early winter. Pruning encourages new growth and maintains an attractive shape. Minimal pruning is required; just focus on the removal of old growth and trimming back as needed to keep the plant healthy and prevent it from becoming too leggy.
Cleaning
As needed
Soil
The Jacob's Rod prefers well-draining soil mixed with sand and peat for optimum growth. The best soil mix would be equal parts of loamy soil, coarse sand, and peat to ensure good drainage and aeration. The soil pH ideal for Asphodeline liburnica is slightly alkaline, around 7.5 to 8.0.
Repotting
Jacob's Rod typically requires repotting every two to three years. Asphodeline liburnica should be repotted when it outgrows its current container, which is generally noticeable when the roots start to circle the pot's bottom or protrude through the drainage holes.
Humidity & Misting
Jacob's Rod thrives best in moderate humidity conditions. The plant is accustomed to the dry Mediterranean climate, so it is tolerant of less humid conditions, but does not require high humidity levels found in more tropical environments.
Suitable locations
Indoor
Place in bright, indirect light and keep soil moderately dry.
Outdoor
Plant in full sun, in well-draining, lean soil.
Hardiness zone
5-9 USDA
Life cycle
Asphodeline liburnica, commonly known as Jacob's Rod, begins its life cycle when seeds germinate, usually requiring well-drained soil and plenty of sunlight. The young seedlings develop a root system and foliage, forming a rosette of narrow, lance-shaped leaves. As the plant matures, it develops a flowering stalk, which can reach up to 60 cm tall, bearing yellow star-shaped flowers that bloom from late spring to early summer. After pollination, typically by bees, the flowers develop into three-chambered capsules containing black seeds. Once the seeds are dispersed by wind or animals, the plant enters a period of dormancy during the colder months. Annual growth occurs in the spring when environmental conditions become favorable again, continuing the cycle.
Propogation
Propogation time
Spring-Early Summer
Asphodeline liburnica, commonly known as Jacob's Rod, is typically propagated through division, which is a popular method for this perennial plant. The best time to divide and propagate Jacob's Rod is in the spring or early fall, when the plant is not in active bloom. The process involves carefully digging up an established clump of the plant and gently teasing apart the root mass into several sections, each with an adequate amount of roots and shoots. These sections are then planted in well-draining soil, preferably enriched with organic matter, at the same depth they were growing previously. It is important to water the new divisions thoroughly after planting to help establish them. Proper spacing should be considered to allow for mature growth, generally around 18 inches to 24 inches (approximately 45 to 60 centimeters) apart.
