Some flowers have such a good balance between their low care requirements and their beautiful blooms that they seem to be in everybody's yard. Though it's easy to become desensitized to common yard flowers, these popular flowers show up frequently because they have so much to offer the gardener. Mixing common garden flowers with other more unusual flowers can help create a long-lasting and beautiful garden.
Shasta daisy (Leucanthemum X superbum) is a classic-looking daisy that boasts a cheery yellow center framed by crisp white petals. The perennial is quite hardy and low maintenance, and a common sight in gardens in USDA zones 5 to 9. The stiff stalks and attractive blue green foliage of the plant make shasta daisy excellent as a cut flower. Shasta daisy grows best in full sunlight in limey soils that are well drained. Water the plant frequently during the growing season, but withhold water during the winter--too much water in the colder months can quickly cause root rot, leading to the death of the plant.
French marigolds (Tagetes patula) are frost-tender annuals that are a common sight in USDA zones 9 to 11. The plant boasts rich blue green foliage and fluffy, multilayered flowers in fiery shades of yellow, orange and red. The plants are often used in annual flower beds or borders. Marigolds require very little care, and will grow in most soil types. The drought-tolerant plant grows best in full sun or sun with a little afternoon shade. Water marigolds as needed, and deadhead the flowers to keep the plant blooming throughout the season.
Bearded iris (Iris germanica) is a common sight in temperate gardens across the world. In the United States, the popular flower can grow anywhere from USDA zones 4 to 10. The perennial plant boasts fleshy, lush green foliage and floppy flowers that are orchidlike in appearance. Bearded iris is available in a range of colors, from blackish purple to bright yellow or blue depending on cultivar. Grow the plant in full sunlight, with a little shade in the afternoon in warmer climates. The plant isn't picky about soil, but requires frequent watering until fully established. Once established, the plant only needs water during the hottest summer months.
