Thunderchild Flowering Crab
Early Blue Violet

Thunderchild Flowering Crab is a hybrid crab apple known for its attractive and fragrant dark pink blossoms and deep purple mature leaves.

Tree farmers will find this hybrid appealing as a pollinator for other apples, while home growers will enjoy the red pome's ability to attract flocks of Cedar Waxwings in the early spring.

This species is reportedly resistant to fireblight.

Early Blue Violet is a low-growing native perennial wildflower valued for its striking early-spring blooms. The flowers range in color from vibrant blue to deep violet, often marked with pale highlights and fine white hairs. They provide an important early nectar source for pollinators and serve as a host plant for several fritillary butterfly species.

It spreads by both seed and rhizomes, gradually forming small colonies. Its dark green, heart-shaped leaves add ornamental appeal, and the plant shows some resistance to deer browsing. Early Blue Violet is well-suited to naturalization projects and pollinator-friendly gardens, and has also been used in coastal butterfly habitat restoration in the Pacific Northwest.
