About Gaillardia 'Arizona Sun'

Gaillardia x grandiflora 'Arizona Sun' · also called Arizona Sun blanket flower · flowering

Gaillardia 'Arizona Sun' is an award-winning compact blanket flower bearing large mahogany-red daisies edged in bright yellow from early summer until frost. Bred for uniform, fast flowering from seed, it loves full sun and dry, well-drained soil, tolerates heat and drought, and is a magnet for bees and butterflies.

Mature size: About 30 cm tall and 30-40 cm wide (12 in by 12-16 in).

Indoor size vs how big it gets in the wild

Gaillardia 'Arizona Sun' reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect about 30 cm tall and 30-40 cm wide (12 in by 12-16 in).. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.
