The species of the genus Triteleia have a very characteristic floral morphology. Each flower is made up of three petals and three tepals. (in total six similar pieces that make up the corolla), six stamens and a trilobed stigma sitting on a three-chambered ovaryThe life cycle of the plant starts from underground bulbs called cormsThese corms typically last for one season, but each year they are replaced by new corms that develop between autumn and late spring. After flowering, Triteleia enters its summer dormancy. It is recommended to consult how to do this (https://www.jardineriaon.com/plantas-ornamentales-coleos.html) to prolong the life of the corms.
The usual height ranges between 40 and 50 cmThe leaves are elongated and ribbon-like, light green, and usually wither as flowering progresses. The inflorescence is an umbel that can hold 20 to 25 delicate flowers per stem, reaching up to 15 diameter cmThe flowers last two to three weeks if grown under optimal conditions.
The appearance of this plant resembles a clump of fine grass, from which long flower stems emerge. Triteleia, due to its appearance and color, It provides a very light and elegant visual effect, especially when planted among earlier flowering species, as this prolongs the color in our gardens.

How and when to plant Triteleia bulbs

- Choice of place: Prefers locations of full sun, although it can tolerate the bright semi-shadeDirect exposure promotes color intensity and abundant flowering.
- Soil preparation: It is essential that the substrate presents excellent drainageExcess moisture can rot the corms. It is recommended to improve the soil by incorporating mature compost, vegetable mulch, well-rotted manure or gravel to ensure lightness and aeration. A pH between neutral and slightly acidic It is perfect, but the plant is quite tolerant of small variations.
- Planting depth: The bulbs should be buried between 8 and 12 cm deep, with the tip pointing upwards and the roots pointing downwards.
- Separation: let between 10 and 15 cm distance between each corm to ensure healthy development and avoid competition for nutrients.
- Initial irrigation: After planting, generous watering is recommended to allow the corm to begin the rooting process.
It's advisable to plant bulbs in groups or bunches, as this creates a much more striking and natural flowering effect. You can mix different varieties to create truly spectacular combinations of blue and white.
Essential care of Triteleia
- Irrigation: Watering is essential during the growth and flowering period. You should water regularly in spring and autumn, allowing the top layer of the substrate to dry between waterings. Once the plant enters dormancy (summer), it requires very little water, as the bulbs remain dormant and tolerate drought well.
- Frost protection: The hardiest species can withstand light frosts, but not persistent or extreme frosts. If you live in a cold region, Protect the corms by covering them with a layer of mulch or using frost-resistant fabric. To prevent frost damage, if the weather is very extreme, you can also dig up the bulbs after flowering and store them in a dry, protected place until the following season.
- Pruning and cleaning: It is not necessary to prune the Triteleia, but after flowering it is advisable to remove the dried leaves and flowers To improve the plant's appearance and prevent fungal growth. Don't cut the foliage until it's completely dry, as this is important for the bulbs' nutrition.

Multiplication and propagation of Triteleia
- By division of bulbs: The simplest and most effective way to multiply Triteleia is separating the bulbs after flowering, when the plant begins to dormant. Remove the corms from the soil and carefully separate the new bulbs that have formed around the main one. Transplant elsewhere or save for planting the following season.
- By seeds: It's also possible to propagate the plant by seed, although the process takes longer. If you decide to collect the seeds from the nuts, sow them in a light substrate in the fall. The seedlings can take several years to reach a size sufficient to flower.
