Cuscuta suaveolens: complete guide

Overview

Cuscuta suaveolens, commonly known as Fragrant Dodder or Chilean Seide, is an exceptional parasitic plant native to southern South America. This member of the Convolvulaceae family distinguishes itself through its delicate thread-like growth and pleasant fragrance.

Unlike most plants, Cuscuta suaveolens must always grow upon a host plant. It cannot survive independently. This is a remarkable plant for experimentally-minded gardeners seeking something completely different.

Appearance & Bloom Cycle

Cuscuta suaveolens consists almost entirely of fine thread-like stems that twine around host plants. These stems lack true leaves. The flowers are small, usually white to cream-colored, sometimes with yellow tinges.

What attracts many gardeners is the pleasant sweet fragrance these blooms emit. The bloom period typically occurs from summer through early autumn. The plant produces small seeds in pod-shaped fruits.

Ideal Location

Cuscuta suaveolens thrives in full sun to partial shade. The plant needs ample light to flower well. Choose a warm, sheltered spot. The plant must always grow upon or against a host plant.

Don't position this plant near valuable garden specimens. This is truly a plant for experimental gardeners working with complete control.

Soil

Although Cuscuta suaveolens develops no roots in the soil, the host plant grows best in well-prepared soil. Ensure your host plant receives good, well-draining soil conditions. Optimal pH ranges from 6.5 to 7.0.

Watering

The parasitic plant extracts water from its host. Ensure your host plant receives regular watering, especially during dry periods. Ensure water drains well.

Pruning

No pruning is necessary, but you can control growth by carefully directing stems. Remove excessive thread-like growth to prevent runaway establishment. Be cautious: this plant can become highly invasive.

Maintenance Calendar

April-May: Plant on host. June-July: Growth increases. August-September: Bloom period. October: Seed setting. November-March: Dormancy.

Winter Hardiness

Cuscuta suaveolens is not winter hardy in temperate climates. The plant will die in winter. You can grow it as an annual from seed.

Host Plants

Suitable host plants include alfalfa, red clover, white clover, heliotrope, and cornflower.
