Bumble Rumble is a collarette-type dahlia known for its small, 3–4 inch, pollinator-friendly blooms and distinctive two-tone petals. It is grown mainly for its whimsical look and strong garden presence rather than for very large flowers.​  The blooms have deep pink to raspberry outer petals that are streaked or swirled with lighter pink or white tones, giving a berry-and-cream effect. Inside this ring of larger “ray” petals is a shorter, ruffled collar of pale to white petaloids surrounding a golden yellow open center that is highly attractive to bees and other pollinators.​  Plants generally reach about 24–40 inches tall, making them a medium-height dahlia suitable for borders and cutting gardens. The flowers are borne on branching stems, so plants can produce a good number of blooms over the season when regularly deadheaded.​Bumble Rumble typically flowers from midsummer to frost when planted in spring, providing color for an extended period. Its open center and bright collar make it especially useful in pollinator-friendly plantings and as a conversation piece in mixed borders or bouquet work.​
