White cedar is a USA-NPN regional plant species. Regional species are ecologically or economically important but are distributed more locally than calibration species. The NPN integrates these observations to understand better plant responses within the different geographic regions of the nation.
White cedar is an evergreen to semi-deciduous, large shrub to medium-sized tree growing 20 to 75 feet tall. Its showy, white to pink to light purple flowers have both male and female parts that occur along the branches, mostly in small clusters. White cedar is found on coastland, range, and grasslands, and in planted forests, scrub, and shrublands, and disturbed sites. It grows on any well-drained soil type, adapting to poor or degraded soils if moisture is adequate, although it prefers deep clays. It is drought-tolerant for short periods but is intolerant of freezing and shade.
You should observe...
Here are the phenophases you should observe about this plant.
Leaves Breaking leaf buds

One or more breaking leaf buds are visible on the plant. A leaf bud is considered "breaking" once a green leaf tip is visible at the end of the bud, but before the first leaf from the bud has unfolded to expose the leaf stalk (petiole) or leaf base.
Leaves

One or more live unfolded leaves are visible on the plant. A leaf is considered "unfolded" once the leaf stalk (petiole) or leaf base is visible. New small leaves may need to be bent backwards to see whether the leaf stalk or leaf base is visible. Do not include dried or dead leaves.
Increasing leaf size

A majority of leaves on the plant have not yet reached their full size and are still growing larger. Do not include new leaves that continue to emerge at the ends of elongating stems throughout the growing season.

Flowers Flowers

One or more fresh flowers or flower heads (inflorescences) are visible on the plant. Flower heads include many small flowers that usually do not open all at once. Do not include wilted or dried flowers that remain on the plant, or heads whose flowers have all wilted or dried.
Open flowers

One or more open fresh flowers are visible on the plant. Flowers are considered "open" when the reproductive parts (male stamens or female pistils) are visible between unfolded or open flower parts. Do not include wilted or dried flowers that remain on the plant.

Fruits Fruits

One or more fresh fruits are visible on the plant.
Ripe fruits

One or more ripe fruits are visible on the plant.

Recent fruit drop

One or more fresh mature fruits or seeds have dropped or been removed from the plant since your last visit. Do not include obviously immature fruits that have dropped before ripening, such as in a heavy rain or wind.
Tabebuia heterophylla is used for reforestation and ornamentation. Its wood is used for furnishings, furniture, tool handles, boxes and crates, and sporting goods. In some areas of the world, it is a favored wood for boat-building.
