Christella acuminata aka Christella Acuminata

Christella acuminata is native to parts of eastern Asia. Its growth form is a rhizomatous geophyte. This term refers to its stems below the ground. These stems are called rhizomes. Kew’s World Checklist of Vascular Plants gives its native range. That range runs from China into temperate East Asia. Kew also records this plant in Vietnam and the Philippines. Within the Philippines, the range includes the Babuyan Islands. It also includes the north of Luzon. Kew describes the plant’s climate as temperate. This climate label does not give tested advice for garden care.

The sources record rhizomes but give few other growth details. They give no height for a full-grown plant. They give no spread for a full-grown plant either. Thus, they do not show how much space it needs. They do not describe the plant’s leaves. Nor do they describe its stems above the ground. There is no account of changes through the seasons. These gaps limit what we can say about its form. The record of stems below ground does not fill those gaps. It gives no fuller picture of the plant’s size or looks.

The RHS accepts the name Christella acuminata. It places the plant in the family Thelypteridaceae. The supplied Kew record lists the family as Aspleniaceae instead. The two sources thus differ on which family it belongs to. The supplied evidence does not settle that difference. Both family names remain part of the supplied account. The RHS page deals with this species itself. It states that the plant is not native to Britain. It says the same for Ireland.

The evidence gives no tested ways to grow this plant. It gives no hardiness ratings to guide its use. It does not state its needs for light or water. It gives no soil needs or advice on feeding. Nor does it document uses in a garden. It gives no account of pests or diseases. It does not name any parts as fit to eat. It gives no account of toxicity, or risk of poisoning. These gaps do not prove that the plant is safe. Nor do they show that it is easy to grow.
