When creating a list of pure white flowers for your garden, take into consideration that many flowers come in a wide variety of colors. Identifying the particular pure white varieties of different plant species, such as the "Clear White" Lantana flower, will remove the guesswork from your color palette and provide a greater medley of flower shape and size.
Crysanthemums (Dendranthema morifolium), often referred to as garden mums, bloom in the fall and remain in bloom until the cold temperatures of winter. Acting as perennials or annuals depending upon region, crysanthemums are well known for their vivid display of color. Of the many cultivars producing white flowers, the pure white flower cultivar is "Patriot." Displaying a pompon flower during mid to late season, patriot is a spreading crysanthemum plant, according to the Clemson University Extension. Crysanthemums thrive in full sun, prefer fertile, well-drained soil and can grow to a height of 1 1/2 to 3 feet in height.
Lantana plants (Lantana camara) are rapid growers and are known for their resilience. Thriving in hot weather, full sun and well-drained slightly acid soil, the cultivar "Clear White" displays pure white flowers. A low-spreading lantana plant, clear white can be pruned during the summer months; repeat blooming is made possible through light shearing, according to the Clemson University Extension. Clear white lantana plants may be used as annuals or perennials for ground cover or in hanging baskets. Low-spreading lantanas grow to a height of 1 to 2 feet and a width of up to 4 feet.
A highly vigorous plant, daffodils (Triandrus spp.) provide vibrant color and are available in a variety of cultivars producing pure white flowers. Thriving in at least a half a day of sunlight, daffodils prefer well-drained, medium-heavy loam soil and grow up to a height of 14 inches. Since there are different characteristics of different daffodil varieties, 13 divisions categorize them based on form. Two pure white flower cultivars come from Division 5 (Triandrus narcissi); daffodils in this division have clustered, softly pointed flowers, as explained by the University of Missouri Extension. "Thalia" displays two or three pure white flowers and "Petrel" displays two to three pure white flowers per stem, according to the Iowa State University Extension.
