Cactus lilies are exotic houseplants that need a few care tips to ensure they develop magnificently - species-appropriate overwintering is particularly important.
The Cordyline (Cordyline) can be found in various species and varieties as an ornamental plant. The various leaf colors ensure an exotic flair in your home. In this article, we show which species need to be overwintered and cared for, so that you can enjoy them for a long time.
Origin and Characteristics
Ocean lilies are native to the tropical forests of Australia and New Zealand. In this country, they are popular potted plants that add a touch of the exotic. They belong to the asparagus family and are related to the dragon tree (Dracaena), which they also slightly resemble in appearance. Because cordylines look like palm trees: Sword-shaped leaves form at the end of the thin trunk. Depending on the species, the leaves are green, red or patterned.
How big do club lilies get?
Cordylines grow to about 150 - 250 cm in pots. This growth height is reached only slowly. In midsummer, older trumpet lilies in particular bloom white and have long panicles. When the flowers have dried up, the shoot splits at this point.
The most beautiful species of club lilies
There are many varieties of club lilies. The two species Cordyline australis and Cordyline fruticosa are common as indoor plants.
Cordyline australis
This species is characterized by its 70 - 90 cm long and up to 5 cm wide sword-shaped leaves without a stalk. It is a cold-tolerant species and should be in a partially shaded location at around 15 - 20 °C. It can also be brought outside from May, but should be brought back inside from September. Color and pattern vary between varieties.
- 'Red Star': This red macula is one of the most sold varieties. Their leaves are bronze in colorto reddish.
- 'Torbay Dazzler': This variety is characterized by its green leaves with cream colored edges. The underside of the leaf shows a reddish colored leaf vein.
Cordyline fruticosa
The leaves of this species are up to 50 cm long, are lanceolate and usually have a stalk. The Cordyline fruticosa loves warmth and should be placed in a bright place at temperatures between 18 - 22 °C. The species can be in the garden from June to August. The variation in leaf color and pattern is versatile.
- ‘Glauca’: The leaves of this variety are rather elongated and bright green in colour. Young leaves can appear slightly reddish.
- 'Kiwi': A yellow stripe pattern can be seen on the green leaves. In addition, a red border adorns the leaves. The plants should be in a light position to preserve the colour.
- ‘Mambo’: The reddish coloring is surrounded by a pink border. Young leaves are bronze in colour. Choose a bright location to preserve the reddish colour.
- 'Tango': This variety is characterized by the irregular green-pink variegation of the leaves. To increase the pink proportion of the leaves, the plants should be light.
Plants: location as indoor plants and in the garden
In our latitudes, club lilies are indoor plants because they are not frost-free. In the semi-shade and with sufficient humidity, they can also find a place on the terrace, the balcony or in the garden in summer.
But first they should be repotted after purchase. The substrate must be loose to prevent waterlogging. Here, for example, our Plantura organic potting soil is suitable. It consists of 100% natural raw materials and is also peat-free. There is some expanded clay in this soil, so the soil stays loose longer. Since club lilies need a very draining substrate, a further addition of 20% expanded clay is recommended. A drainage layer on the bottom of the pot also proves its worth.
Due to the slow growth of the club lily, annual repotting is not necessary. If a high-quality soil was used, it is sufficientputting them in fresh substrate every two to three years. However, you don't necessarily need a larger pot: this should only be chosen if the root system is already touching the edges of the pot.
Which location to choose for club lilies?
Both the Cordyline australis and the Cordyline fruticosa should be placed in a light to partially shaded location without direct sun if possible. Variegated varieties in particular like a bright spot so that the color of the leaves is preserved.
The air should not be too dry, otherwise brown tips can easily occur. Spraying the leaves with lime-free water every week can help here. A bowl of water and expanded clay balls under the pot can also prevent a lack of humidity. Especially in winter, the humidity in rooms is very low due to dry heating air. A bright bathroom is a good location for tiger lilies because of the high humidity.
The room temperature should not be too warm. Cordyline australis tolerates somewhat colder temperatures between 15 - 20 °C. Cordyline fruticosa should be in a room with 18 - 22 °C. Permanent damage may occur to this species at temperatures below 18°C for extended periods.
Can thorn lilies be in the garden?
Cactus lilies can be kept in pots in the garden, on the terrace or on the balcony in summer, mainly from June to August. A wind-protected, half-shady location is important. In a place in direct sun, you should pay attention to an increased watering to compensate for the transpiration of the leaves. Both club lily species should move back into the house or apartment in autumn. The Cordyline australis needs a cool place to hibernate to protect it from pests. An unheated but frost-free greenhouse is suitable for this.
Caring for the club lily: pruning and more
Caring for the club lily is not complicated, it is an undemanding plant. Nevertheless, certain points must be observed:
Pruning, watering and fertilizing
Pruning a club lily is not strictly necessary. If you prefer a bushy, dense growth, pruning can help. Even if the plant is out of shapeadvised, the cutting of shoots is recommended. Because the club lily will sprout again at the cutting edge. The cut off part can be used as a cutting for propagation. Pruning may also be necessary if the tiger lily is too large.
There are several tips to keep in mind when watering. Club lilies like a moist root ball. It should never dry out completely. However, waterlogging must also be avoided to prevent root rot. In addition, club lilies tolerate low-lime water best. For example, rainwater or stagnant tap water are very suitable. In autumn, at the end of the vegetation period, club lilies should only be watered moderately, with the bulbs remaining moist.
Since club lilies stop growing in winter, the last nutrient application should be in October. At the beginning of the growing season in March, weekly fertilization should start again. This ensures he althy and vigorous growth of the club lilies. For example, our Plantura organic indoor and green plant fertilizer is suitable for this, with which the plants are optimally supplied with the right nutrient ratio. It can simply be administered with the irrigation water.
Tip: Check for thrips infestation all year round. It is also important to check the club lilies for spider mites, especially in winter. Read our special article on how to identify and combat spider mites.
Brown leaves on the club lily: what to do?
If only the oldest leaves on the tiger lily turn brown and shed, there is no reason to worry at first. It is a natural process that creates the palm-shaped crown. However, if more brown or yellow leaves can be seen on the club lilies, this can have several causes:
Nutritional deficiency: Leaves that turn yellow and then fall off can indicate a nutrient deficiency. The weekly fertilization of the club lily should be included.
Air dryness: If the air humidity is too low, the tips of the leaves in particular will quickly turn brown. Spraying lime-free water on the leaves weekly will ensure adequate moisture.
Root Rot: Too much stagnant water in the root ball causes the root system to rot. This leads to discoloration of the leaves with subsequent leaf loss. The rotten roots mustremoved as soon as possible and the pad should be allowed to dry. In this respect, it is not allowed to continue pouring for the time being. Once the root ball has dried, watering should be slowly resumed. However, the amount of water should always be reduced in order to prevent the remaining roots from rotting again.
Is the club lily hardy?
Club lilies are not hardy, they are particularly sensitive to frost. Therefore, club lilies should find a place in the house or apartment for the winter. A cool ambient temperature of about 5 - 10 °C must be ensured. A bright location is recommended and overwintering is also possible in the conservatory or frost-free greenhouse. A cool place usually prevents infestation with pests.
Propagating Club Lily
To propagate the club lilies, cuttings are recommended. These should be cut in the summer months to ensure the best possible chance of successful rooting.
Head cuttings are possible, i.e. section of the shoot tips. The cutting may have one leaf, additional leaves should be removed. Stick it in a 1:1 mixture of sand and soil. The substrate should be loose and have a reduced nutrient content adapted to cuttings. This is the case, for example, with our Plantura organic herb and seed soil. In addition, it consists of 100% natural raw materials and is peat-free. If the soil is kept moist, the cuttings will root at 18 - 21 ° within about eight to twelve weeks. It is also possible to root the club lily head cuttings in a glass of water. The rooted club lily can be planted in the desired pot and placed in a suitable location.
Stem cuttings often have no leaves. They are cut further down the club lily and should have at least two leaf nodes. Root formation is stimulated by two longitudinal cuts that are placed directly on the sand-soil mixture. The shoot cutting lying on the growing substrate is kept moist and develops roots and leaves within two to three months.
Is the mace lily poisonous?
The club lily is non-toxic to humans and cats, but the saponins it contains are slightly toxic to dogs. An additionalThe sharp-edged leaves, which can easily lead to injuries in the mouth, are dangerous for children and animals. A certain degree of caution is therefore required when choosing the location.
In addition to the club lily, there are other exotic houseplants that create a special atmosphere in your home.
