Plant Profile: Tradescantia 'Purple Profusion' (Andersoniana Group)

Spiderwort derives its name from the thick, sticky fluid that oozes from the stem when it is cut. This fluid solidifies into a thread-like, silky texture, resembling a spider's web.

The plant thrives best in soils rich in acidity but can also adapt to neutral or alkaline conditions.

While full sunlight enhances flower production, in hotter regions, a bit of afternoon shade is beneficial.

A single spiderwort plant will not produce seeds; however, when two or more are planted together, they will yield seeds. The resulting seedlings may not necessarily resemble their parent plants.

Typically, spiderwort blooms from May to August. To prolong the blooming period, deadheading—removing spent flowers—from each cluster can be beneficial, also enhancing the plant's overall appearance. Flowering may slow or cease during the peak summer heat, and the foliage may begin to decline as temperatures rise. At this stage, cutting the plant back nearly to the ground can encourage new growth and potentially lead to a late summer or fall bloom.

The 'Purple Profusion' variety is a clump-forming spiderwort celebrated for its striking deep purple flowers accented by bright yellow stamens. Its young leaves exhibit a purple tint, and the flowers are borne in clusters atop sturdy stems, with multiple buds per cluster. The flowers open gradually, each lasting just one day, and tend to remain open longer on cooler or overcast days compared to hot, sunny ones.

In terms of pests and diseases, young shoots may be susceptible to damage from snails and caterpillars. Additionally, the plant can become less appealing during mid-summer when flowers and foliage decline. Regular overhead irrigation may also lead to disease issues.
