Pardanthopsis dichotoma Pardanthopsis dichotoma
(Vesper iris)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

The flowers of vesper iris open in the late afternoon over a period of several minutes, just about the time the sound of evening vespers might have wafted over an old monastery garden. It is a valuable addition to the garden also because of its late blooming season (high summer into early fall) and for its ability to bloom from seed started the same spring. The vesper iris has typical iris-looking leaf fans and abundantly branched, willowy bloom stalks rising to 4 feet. The inch-wide flowers range in color from pure white to violet.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This tropical annual produces mounds of narrow burgundy-red foliage and purple plumes to 1 foot long. It is invaluable for containers and stunning, annual foliage color in a border. It rarely sets seed.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

The Volcano® series of fragrant, abundantly-flowering, compact Phlox has been bred for high levels of natural disease-tolerance. This is wonderful news for Phlox fans, who until now have often had to deal with powdery mildew when growing other Phlox varieties. -Anthony Tesselaar Plants

Plectranthus ‘Mona Lavender’ Plectranthus ‘Mona Lavender’
(2 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Plectranthus cultivars are popular foliage plants, but some gardeners grow them for their blooms, and one of the best bloomers is 'Mona Lavender'. This cultivar has abundant lavender-purple flowers that complement the dark green leaves (with purple undersides and stems). These plants thrive in light to deep shade. -Tom Nelson, Regional Picks: Northern California, Fine Gardening issue #127

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Prized largely for its foliage, this spreading evergreen perennial is grown as an annual or under glass.

Psoralea pinnata Psoralea pinnata
(African scurf pea, Blue pea)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This short-lived shrub or small tree with feathery foliage is blanketed in late spring with fragrant, pea-shaped violet blooms with white wings. Though it is native to streamsides, scurf pea doesn't require extravagant watering and survives occasional drought. When the plants eventually die, they leave ample progeny and straight branches useful for garden stakes. Combine with azaleas and camellias, which bloom at the same time.

Ruellia brittoniana 'Purple Showers' Ruellia brittoniana 'Purple Showers'
(Mexican petunia, Common ruellia, Wild petunia)
(7 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This three-foot-tall evergreen shrub bears many tubular, blue or purple, petunia-like flowers on dark stems over a long period. Each flower lasts for just one day. It is a fast grower that may self-seed aggressively. Use in a border, container, or at waterside. Can be grown as an annual in cooler areas.

(Desert ruellia)

This southern California native shrub produces a dense mass of small, glossy leaves and purple, petunia-like flowers in late spring and early summer. Sporadic flowering can occur throughout the season. It grows up to 4 feet tall and 6 feet wide.
