The Baja bush-snapdragon is fine-textured shrub with densely layered arching branches, small blue-green leaves and stems and narrow tubular red flowers. Mature plants mound to 3-6 ft. tall and as wide; flowers that attract hummingbirds and butterflies are heaviest in spring, but also occur intermittently all year.

Endemic to Baja California, this species is well suited for slopes and in background areas in combination with other native plants. It is a carefree plant that can be pruned in late fall to manage its size and shape to fit garden plantings. One cultivar, G. j. Punta Banda, has light green leaves and stems, and a tightly woven branching habit capable of mounding 3-4 ft. tall and 4-5 ft. wide.

Water Needs

Baja bush-snapdragon is well adapted to sunny garden locations on well drained soils and with low amounts of supplemental water during summer. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water; more moisture during the spring months will sustain a more robust and longer flowering cycle.

Prune in late fall to control size, if necessary, and to shape, if desired (4). If damaged by frost in the winter, wait a few weeks before pruning damaged areas. You will want to be sure of the extent of the damage before cutting back (1). If more frost is expected, continue to wait before cutting back because the damaged parts may help protect the healthy leaves and stems from further damage (S).
