Sophora secundiflora is a most desirable shrub or small tree for warm-summer climates, with its showy racemes of scented, violet-blue flowers contrasting with rather dark evergreen leaves (Fredericksburg, Texas, USA – 2 March 2024). Image Julian Sutton.

An evergreen tree 25 to 35 ft high with pinnate leaves 4 to 6 in. long, made up usually of seven or nine oblong or obovate leaflets which are 1 to 2 in. long, notched at the end. Flowers produced in racemes 2 or 3 in. long at the end of the leafy young shoots of the current year in spring. Each flower (of the normal pea-flower shape) is about 1 in. long, violet-blue and very fragrant (like violets).

Native of Texas, New Mexico, and North Mexico. It was figured by Ortega, the Spanish botanist in 1798 from a plant that flowered in Madrid. Decaisne, who figured it in the Revue Horticole, 1854, p. 201, observes that it withstands easily the climate of the midi of France. I do not know that it has been tried out-of-doors yet in this country but it is only likely to succeed in the sunniest, warmest localities and is better fitted no doubt for the south of Europe. It would be worthwhile trying it on a south wall, for Sargent describes it as one of the handsomest of small trees in the Texan forest, and hardy trees with fragrant violet-blue flowers are very rare.

For a couple of weeks at the end of winter the gardens and public spaces of Central Texas towns are full of the colour and scent of Sophora secundiflora (San Antonio, Texas, USA – 29 February 2024). Image Julian Sutton.

Variants of Sophora secundiflora with white or palest violet flowers occasionally turn up in wild populations (Crockett Co., Texas, USA – 4 March 2024). Image Julian Sutton.

At its largest Sophora secundiflora makes a loose, usually multistemmed small tree (wild plant in Government Canyon State Park, Texas, USA – 10 March 2024). Image Julian Sutton.

The indehiscent woody pods of Sophora secundiflora are often retained on the plant for many months. They contain 1 (as here) to 3 seeds (Austin, Texas, USA – 24 February 2024). Image Julian Sutton.

When crushed, the pods of Sophora secundiflora reveal the brilliant scarlet (and extremely poisonous) seeds (San Antonio, Texas, USA – 11 March 2024). Image Julian Sutton.
