West Indian topical bulb cultivation generally refers to the growing of plants with bulbs, corms, or rhizomes in tropical and subtropical regions. Many of these plants are popular ornamental species, and some also have medicinal or edible uses. Key considerations include appropriate planting depth and spacing, sunlight and water requirements, and winter care, particularly in regions with cooler winters.
Popular West Indian Bulbous Plants and their Cultivation:
Canna (Canna indica):
Also known as achira, this plant is cultivated for its edible rhizomes and ornamental value. It thrives in tropical and subtropical climates and can be propagated from rhizomes, seeds, or division.
Water Lilies (Nymphaea spp.):
These are popular for water gardens, with different species blooming at different times of the day. They are typically grown in pots or directly in the water, with rhizomes planted in rich soil.
Spider Lily (Hymenocallis spp.):
This plant is grown for its attractive flowers and is commercially cultivated in western India. It prefers well-drained soil and bright, indirect sunlight.
Ixora (Ixora spp.):
While not strictly a bulb, it's often grouped with tropical plants and is known for its vibrant, long-lasting flowers. Ixora thrives in full sun and well-drained soil, requiring regular watering and occasional fertilization.
Taro (Colocasia esculenta):
This plant is grown for its edible corms and is a staple food in many tropical regions. Taro prefers warm, moist conditions and can be grown in both soil and water.
Drimia indica:
This plant, also known as Indian squill, is used in traditional medicine for its anthelmintic properties, and its bulbs are cultivated for this purpose.
General Cultivation Tips:
Planting Depth: Smaller bulbs should be planted 4-6 inches deep, while larger ones should be planted 6-8 inches deep.
Spacing: Spacing depends on the specific plant and its mature size.
Sunlight: Most tropical bulbous plants prefer full sun, but some may benefit from partial shade during the hottest part of the day.
Watering: Water regularly, keeping the soil moist but not soggy.
Winter Care: Some species may need to be protected from frost during winter by bringing them indoors or providing extra insulation.
Soil: Well-drained soil is generally preferred.
Propagation: Bulbs can be propagated from offsets, bulbils, or seeds, depending on the species.
