Description

Grape soda lupine gets its name from its sweet grape-like flower fragrance. It is a small shrubby perennial growing to 2-3 ft. tall and spreads 4 ft. wide with silvery foliage and tall spikes of purple-blue flowers. One of the easiest to grow in gardens for bold spring color value; it often reseeds and generates new seedlings that can be easily removed if desired.

The Grape soda lupine is a colorful flowering perennial that combines well with native plants and in Mediterranean garden plantings. It is adapted to full sun, well drained soils and low amounts of summer water throughout the Inland Empire. Trimming in late fall or winter helps to maintain its size and to renew good foliage character.

Water Needs

The Grape soda lupine is highly adapted to sunny garden locations on well drained soils and with low amounts of supplemental water. 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 water in the spring will result in a longer flowering season.

Maintenance

Tends to be short lived in most gardens (S). Do not prune into old wood as it will not grow back from cuts in these areas. Dead head spent flower stalks if desired, however the seeds are good bird food (S). Prune into younger branches in late fall or winter to help control size and encourage new foliage growth (4).
