Mango — Langra

Langra is a named cultivar of the mango (Mangifera indica ‘Langra’), the familiar tropical fruit tree of the cashew family, Anacardiaceae.⁴ Because Langra is a selection within the common mango species, it shares almost all of its growing requirements, climate tolerances, and botany with mango in general, while a handful of traits—chiefly its standing as a high-quality dessert mango—are particular to the cultivar.² Mango itself originated in India and the surrounding parts of tropical Asia, and Langra belongs to the traditional North Indian group of cultivars grown widely in Uttar Pradesh, Bihar, and adjoining regions.²³⁴ For the homesteader in a frost-free climate, it is a long-lived evergreen that, once established, returns a crop of eating fruit year after year from a single planting.

The mango is an evergreen tree that in favorable conditions can reach roughly 30 metres tall and about as wide, though garden trees are usually kept far smaller by pruning.³⁴ Its leaves are simple and alternate, typically oblong to lance-shaped, around 15 to 30 centimetres long, on stalks 1 to 12 centimetres long; new flushes often emerge reddish and darken to deep green as they mature.¹³ Flowering occurs in large terminal panicles carrying many small whitish to yellowish flowers.¹³ Indian pomological descriptions class Langra as a table, or dessert, mango of high eating quality, generally medium-sized with greenish-yellow fruit, relatively low fibre, and a rich, sweet flavour; precise figures such as average fruit weight and sugar content vary from site to site and are not consistently reported, so they are best treated as variable rather than fixed.²

Growing Mango — Langra

Mango is grown across tropical and warm subtropical regions, and it is decidedly a warm-climate tree.¹³ The University of Florida (UF/IFAS) lists Mangifera indica as suited to USDA hardiness zones 10B to 11, and treats it as a warm-climate fruit tree for South Florida only; the tree is cold-sensitive and is not recommended where frost is regular.¹ Outdoors in the continental United States, Langra is realistically grown only in frost-free zones 10B to 11, with container or greenhouse culture the practical option for colder areas, as for other mango cultivars.¹ The tree grows from sea level to about 1,200 metres in tropical latitudes, although most commercial dessert types, including the Indian cultivars, do not bear consistently above roughly 600 metres of elevation.³

Reliable flowering and fruiting depend on a distinct cool, dry period: one extension guide notes that night temperatures of about 8 to 15 °C (46 to 59 °F) together with day temperatures around 20 °C (68 °F) are associated with good floral induction.³ Where the climate suits it, mango does best in deep, well-drained ground; standing water and frost are its main enemies.¹

Propagation is the key thing to get right with a named cultivar like Langra. Mango trees are commonly propagated by grafting or budding onto seedling rootstocks, and UF/IFAS specifically recommends budding or veneer grafting onto seedling roots.¹³ Seed will not come true to type, so growing a stone from a Langra fruit will not give you a Langra tree; to keep the cultivar you must propagate clonally, grafting scionwood taken from a known Langra tree onto rootstock.¹³ A grafted tree also begins bearing sooner and stays a manageable size more readily than a seedling. Because Langra is botanically a mango like any other, its habit is best assumed to match other traditional Indian cultivars—large, spreading trees unless held in check by pruning—with exact dimensions varying by rootstock and management.²

Harvest and uses

Langra is grown for its fruit and is valued as a dessert mango with high eating quality, the fruit medium-sized, greenish-yellow, comparatively low in fibre, and richly sweet.² As a clonally maintained cultivar, every grafted Langra tree carries the same fruit character as its parent—the whole point of choosing a named variety over a chance seedling.¹² Source-verified figures for harvest timing, per-tree yield, and fruit weight specific to Langra are not consistently documented in the reliable literature, so this profile does not quote them; expect the eating-fruit character described above and treat precise numbers from other sources with caution.²

How to identify it

At the tree level, look for an evergreen with simple, alternate, oblong-to-lance-shaped leaves 15 to 30 centimetres long, with new growth flushing reddish before turning dark green, and large terminal panicles of many small pale flowers in season.¹³ While M. indica traces to India and tropical Asia, the genus Mangifera has its greatest diversity in the Malay Peninsula, Borneo, Java, and Sumatra.³⁵ A specific cultivar such as Langra cannot be told apart from other mangoes by leaf or flower alone; reliable identity comes from propagating a tree of known origin, since cultivar names attach to clonal lineages.²⁵
