Light Requirements
Chelone glabra L. var. linifolia Coleman typically thrives in partial to full shade and moist environments. These plants are particularly sensitive to direct sunlight, and too much of it can lead to drying out of the soil and stunted growth.
Temperature Requirements
This plant variety grows well in cooler temperatures and can survive frost. The ideal temperature range for Chelone glabra var. linifolia Coleman is between 65-75 degrees Fahrenheit during the day and around 50-60 degrees Fahrenheit at night.
Soil Requirements
Chelone glabra L. var. linifolia Coleman prefers well-draining, moist soil that is rich in organic matter. Soil pH should be slightly acidic, between 5.5-6.5, for optimal growth. These plants do not tolerate drought or waterlogged conditions and should be watered regularly to maintain moisture in the soil.
Cultivation Methods
Chelone glabra L. var. linifolia Coleman, commonly known as white turtlehead, is a herbaceous perennial plant that requires full to partial sun exposure. It can grow up to a height of 2-3 feet and a spread of 2-3 feet. Ensure that the soil has good drainage and is rich in organic matter. White turtlehead can tolerate dry to moist soil conditions.
Watering Needs
White turtlehead requires regular watering during its initial growth phase. Water the plant thoroughly once or twice a week, depending on the rainfall and temperature in your region. The plant prefers moist to wet soil conditions, so ensure the soil is not completely dry before watering.
Fertilization
White turtlehead does not require frequent fertilization. However, it can benefit from an annual application of organic fertilizer in the spring. You can use compost or well-rotted manure to enrich the soil. Avoid using high-nitrogen fertilizers as they can promote excessive foliage growth at the expense of flower production.
Pruning
White turtlehead requires minimal pruning. You can deadhead the spent blooms to encourage the production of new flowers. In the fall, you can cut back the stems to the ground level once the foliage starts to die back. This will help prepare the plant for the winter dormancy phase.
Propagation of Chelone glabra L. var. linifolia Coleman
Chelone glabra L. var. linifolia Coleman, commonly known as white turtlehead, can be propagated through seed, cuttings, or division.
Propagation by seed
The seeds of Chelone glabra can be sown in early spring or fall. The seeds can be directly sown in the ground or started indoors and transplanted later. The seeds need to be stratified for a few weeks in a refrigerator to enhance germination. The seeds should be planted in a well-draining soil mix and kept moist until they germinate. It may take two to three weeks for the seeds to germinate.
Propagation by cuttings
Chelone glabra can also be propagated through stem cuttings. Cuttings of new growth should be taken in early summer when the plant is actively growing. The cuttings should be around 4-6 inches long and should have a few leaves attached. The cuttings should be dipped in rooting hormone and planted in a well-draining soil mix. The cuttings should be kept moist and in a shaded area until they root, which may take several weeks.
Propagation by division
Chelone glabra can also be propagated through division. The best time to divide the plant is in the spring or fall when the plant is not in bloom. The clump should be lifted and divided into smaller clumps using a sharp knife or spade. Each division should have a few shoots and roots. The divisions should be replanted in a well-draining soil mix and kept moist until they become established.
