Texas Redbud (var. texensis) Cercis canadensis var. texensis variety

Native

Texas Redbud (var. texensis) is a perennial tree native to the lower 48 states. It grows to 12 ft and blooms Mar in full sun, with brown fruit.

More about this plant

Cercis canadensis, the eastern redbud, is a large deciduous shrub or small tree, native to eastern North America from southern Michigan south to central Mexico, west to New Mexico, but able to thrive as far west as California and as far north as southern Ontario. It is the state tree of Oklahoma and the official city tree of Huntington Beach. The prevalence of the so-called "Columbus strain" has seen the residents of Columbus, Wisconsin, embrace the plant in their city's identity. Known as the "Redbud City," the town hosts "Redbud Day" annually the Saturday before Mother's Day, organizing a variety of themed events to recognize the tree. Wikipedia →

❧ Caterpillar hosts ~19 caterpillar species

Cercis supports ~19 caterpillar species.

Native butterfly & moth caterpillars are the base of the terrestrial food web — most songbirds rear their young almost entirely on them. As a host for native Lepidoptera this is a moderate genus.

Keystone count (genus-level) from Warren II 2026 (CC0) · Tallamy host-use records. Named species (a documented Nearctic sample, not exhaustive) from NHM HOSTS (CC0).

How we know this (1) Methods & honest limits
Mature width Derived

For woody plants that have a height but no measured crown, we estimate width = height × a crown-to-height ratio fit for that plant’s form (conifers narrower than broadleaf trees, shrubs widest), calibrated on our measured open-grown crowns and capped at the largest one ever measured. A measured crown always wins; herbaceous plants get nothing (no anchor).

Honest limits: A coarse class-median estimate for garden-scale spacing, not a measurement; woody single/multi-stem forms only.

Allometric basis: Jucker et al. 2022 (Tallo); Pretzsch et al. 2015; McPherson et al. 2016 (USDA Urban Tree DB).
Derived values are computed from open data by a published method — labelled, cited, and never shown as a direct observation. Full methodology →
