A new and distinct Pelargoniumxhortorum cultivar named Starburst Red is provided. This new Zonal Geranium cultivar was the result of a controlled breeding program wherein an unnamed plant designated 4077-1 was pollinated by the BSR-177 White cultivar (U.S. Plant Pat. No. 8,284). The new cultivar forms attractive multi-patterned single florets that are red, white, and pink in coloration. Attractive medium green foliage is well retained even during shipment. The growth habit is somewhat self-branching and does not require the use of a growth regulator.
