- Description
-
Drought and salt tolerant rapidly growing shrub with rather broom-like appearance. Overgrown plants can be severely pruned but avoid cutting into oldest stems. Can provide good erosion control on hills.
Insects, Diseases, and Other Plant Problems: No serious insect problems. Susceptible to leaf and stem blight. It is a short-lived shrub but tends to reseed itself. It can be weedy and rapidly grow to crowd out native plants. If plants are unwanted, pull them before they flower and set seed. Some non-seeding cultivars are available.
Quick ID Hints:
- Pea-like flowers in late spring along green stems
- Leaves trifoliate on lower stem, one leaflet on upper stem
- Stems have 'twizzler stick' appearance
- Twiggy, mounded shrub with arching stems
- Flowers yellow, or red, pink hues
Deciduous shrub to 6.5', arching and broad-rounded.
Blooms in late spring to early summer; cultivated for floral state which lasts 1-2 weeks, otherwise looks like dead, arching twigs; leaves usually gone by mid-June; stem more grooved and twisted than C. X praecox and usually blooms later and is usually a larger plant; there are also pink and crimson cultivars.
Tolerates poor soils, shade; rapid growth; relatively pest-free.
