Colin Mills, compiler of the Hortus Camdenensis, died in late November 2012 after a short illness. As he always considered the Hortus his legacy, it is his family's intention to keep the site running in perpetuity. It will not, however, be updated in the near future.

Parkinsonia aculeata L.

Frost-tender, small, spreading, often weeping, deciduous tree with spiny green stems, slender, 2-pinnate leaves with many tiny leaflets which fold up at night, and racemes of 2-15 cup-shaped, sweetly scented bright yellow flowers with orange markings and stamens, to 2cm across, in spring.  To 10m.  In dry, frost-free areas it is suitable for hedging and screening, its light, open structure allowing turf and other plants to thrive in its shade.  [RHSE, Hortus].
