Roots of older plants are far stronger and more bitter than those of younger plants. [citation needed] Oshá plants form large clumps over time, and can grow to be very large. In areas of New Mexico, Colorado, and Utah, oshá can reach heights of 6 to 7 feet and produce circular colonies with dozens of root crowns growing from a central root mass.
The correct environment of air, mineral nutrients and water directs plant roots to grow in any direction to meet the plant's needs. Roots will shy or shrink away from dry [22] or other poor soil conditions. Gravitropism directs roots to grow downward at germination, the growth mechanism of plants that also causes the shoot to grow upward. [23]
Conopholis americana is parasitic on the roots of woody plants, especially oaks (genus Quercus) and beech (genus Fagus). [3] The only part of the plant generally seen is the cone-shaped inflorescence, [5] which appears above ground in spring. [6] The entire structure is a yellowish color, turning to brown. [3]
Typically, its stems are branched and the clump forming plants emerge in late spring after most other plants have begun growth for the year. The oppositely arranged leaves are 7.5 to 15 cm (3 to 6 in) long and 1 to 4 cm ( 1 ⁄ 2 to 1 + 1 ⁄ 2 in) wide and are narrow and lance-shaped , with the ends tapering to a sharp point.
A tea prepared from the root was thought to cure boils. [9] In Ireland and the United Kingdom, the plant is often found growing near stinging nettles and there is a widely held belief that the underside of the dock leaf, squeezed to extract a little juice, can be rubbed on the skin to counteract the itching caused by brushing against a nettle ...
The apical meristems start growing and give rise to the root and shoot. The first "true" leaves expand and can often be distinguished from the round cotyledons through their species-dependent distinct shapes. [1] While the plant is growing and developing additional leaves, the cotyledons eventually senesce and fall off.

On top of the gradual growth of the plant, the image reveals the true meaning of phototropism and cell elongation, meaning the light energy from the sun is causing the growing plant to bend towards the light aka elongate. Plant growth and development are mediated by specific plant hormones and plant growth regulators (PGRs) (Ross et al. 1983). [10]
