It is present in Cephalotaxus
and Torreya but absent in the other genus of Taxaceae, Taxus.

Another natural compound, homoharringtonine, isolated from Cephalotaxus
harringtonia (Knight ex J.
Homoharringtonine is extracted from Cephalotaxus
harringtonia which is identified to be a cytotoxic alkaloid and is generally reported to block the progression of cells from G1 phase in to S phase and G2 phase into M phase (61).
Cephalotaxine, which has remarkable anticancer effect, is produced by plants of the genus Cephalotaxus

The more light, the better chance plants will have to compete with tree roots." Among her favorites to compete with roots are drought-tolerant plants like coral bells, hellebores, epimedium, crested iris, anemone, microbiota, plum, cephalotaxus
, nandina, wahoo, dogwood and serviceberry.
If it has already, then because surgery will involve mutilating the hedge by cutting into old wood, which will not regenerate (unless yew, Cryptomeria, Sequoia, Cephalotaxus
, Torreya) don't bother.
