Passiflora foetida - is native to the desert southwest US and is cold hardy and drought tolerant variety of passionflower grown from zones 8. [1] [2] Passiflora incarnata - Maypop is native to central and eastern United States, and is cold hardy and drought tolerant variety of passionflower grown from zones 5. [8] [9] [10] [11]
Thus a plant's ability to tolerate cold, heat, drought, flooding, or wind are typically considered measurements of hardiness. Hardiness of plants is defined by their native extent's geographic location: longitude, latitude and elevation. These attributes are often simplified to a hardiness zone.
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations.
It is cold- and frost-tolerant, [3] growing in USDA hardiness zones 4a-8a, [1] but does not grow well in shade. [ 6 ] [ 4 ] It grows well on slopes [ 4 ] and disturbed soil, [ 3 ] and is sometimes used to stabilize soil. [ 6 ]
The loss of frost resistance occurs after warming. Rapid temperature fluctuations during winter deharden trees and increase the risk of spring damage. [5] Species that bloom first even before the leaves develop like apricots or peaches, are particularly vulnerable to damage. The reproductive organs, due to their abundant hydration, are easily ...
The genus Chorizema was first formally described in 1800 by Jacques Labillardière in his Relation du Voyage à la Recherche de la Pérouse, and the first species he described (the type species) was Chorizema ilicifolium.
It is among the most heat- and drought-tolerant vegetable species in the world and will tolerate soils with heavy clay and intermittent moisture, but frost can damage the pods. In cultivation, the seeds are soaked overnight prior to planting to a depth of 1–2 cm (3 ⁄ 8 – 13 ⁄ 16 in).
Telfairia occidentalis is a tropical vine grown in West Africa as a leaf vegetable and for its edible seeds.Common names for the plant include fluted gourd, fluted pumpkin, ugu (in the Igbo language), "Eweroko" (in the Yoruba language),okwukwo-wiri (in Ikwerre language), and ikong-ubong (in the Efik and Ibibio languages), "Akwukwor ri" (in Etche language).
