White cactus flowers images. Cactus plants are native to the Americas and grow throughout the western and southwestern United States, as far north as Utah and Idaho. The plant has adapted to survive in rough, inhospitable terrain with poor soil and little water and is leafless, with swollen stems and spines. Over 2,000 species exist. All of them produce blossoms and fruit, but only two--saguaro and organ pipe cactus--produce white flowers. Cacti make attractive (if thorny) landscape plants in warm, dry climates and provide habitats and food for birds and wildlife. Grow miniature varieties as house plants.

Heather flowers pictures information.

Heather (Calluna vulgaris) Scotch Heather/Ling Heather, is an evergreen branching shrub. Heather flowers bloom in late summer. Wild species of Heather flowers are usually in purple or mauve shades. The flower's various cultivars come in colors ranging from white, through pink, a wide range of purples and reds. Different varieties of Heather flowers bloom from late July to November in the northern hemisphere. The flowers may turn brown but still remain on the plants over winter, and this can lead to interesting effects.

Heathers are found throughout Western Europe and in some parts of northeastern North America and Siberia. Heather varieties are widely cultivated in rock gardens for cut flower arrangement. A low mound of handsome greenery topped by multiple spikes of colored flowers; Heathers are native to Ireland, Scotland, Scandinavia, Russia, and northern North America. The Heather plant is one of the primary plant species grown on the poor, acid, sandy soils which is typical of heaths.

In Heather flowers, the corolla is showy in true heaths, and in the Erica genus, heathers have showy pink or rarely, white sepals that overlap the corolla. There are two types of Winter Heather plants. The lower, winter spreading types are grown as ground covers, in rockeries, containers or for spot color in flower and shrub beds. While the upright winter varieties are best suited for borders, spot color, massing or as container plants. The flowers of both types are ideal for small winter arrangements.

  Ageratum plants are covered with clusters of small, fuzzy flowers. Most types are mounding plants six to ten inches tall and wide, but there are taller types. Plants bloom from spring planting until frost in fall.

Related varieties: The blues include Blue Horizon for cutting and Blue Lagoon and Blue Danube for pots and bedding.

 How to grow: Grow in any well-drained soil in full sun or partial shade. Space six to ten inches apart for solid colour. Deadhead or shear back slightly if plants become untidy.

  Propagation: Start seeds indoors six to eight weeks before planting. Seeds germinate in five to eight days at 70 degrees Fahrenheit.

Uses: Place in the front of borders and beds. Use them for their scarce blue color, which is seldom found in annuals. Taller, sometimes older, varieties make good cut flowers.

Scientific name: Ageratum houstonianum
