While there are many flowers that open in the morning, only a couple of them are purple. The morning glory is a well-known, trellising vine that blooms in the morning with purple flowers. There is confusion about which plants are actually morning glory, according to master gardeners at Washington State University. Three types of flowering vines are called morning glory, but the real one is the one for your garden. Native California poppies are a bright orange-yellow, but breeders have expanded its colour pallet to include purple as well. These flowers open in the morning and close at night.
Morning Glory or Not
There are three vines commonly called morning glory. according to Master Gardner Carolyn Pauw Barden from Washington State University. Convolvulus arvensis, also called bindweed or wild morning glory, is a noxious weed with white or pinkish-white leaves. It grows by roadsides in ditches and strangles ornamentals and crops alike. Ipomoea tricolour is the lush, vining annual common in gardens and containers. C. tricolour is a shrubby dwarf. It is still pretty, but not the classic morning glory as is the I. tricolour. I. purpurea is the purple variety, and its flowers open every morning and close about noon.
Morning Glory Characteristics and Care
I. purpurea has heart-shaped leaves and spreads indefinitely, depending on its supporting structure. It is native to the Southeast United States and grows well in warm climates. Its flowers are funnel shaped, pinkish-to-purple and 2-1/2 to 3 inches wide. Morning glories don't require much more than moist soil, full sun and a trellis to climb. The trellis isn't necessary. A morning glory will vine through taller shrubs, or spill over containers, if that's what you want it to do. To ensure a plant full of blooms, deadhead it daily and pinch the leading flower on new vines. After the first frost, remove the plant. It is an annual and won't survive the winter.
California Poppy History and Description
The California poppy (Eschscholzia californica) was named for a physician named Johann Friedrich Gustav von Eschscholtz on an expedition to San Francisco in 1815, according to the University of Wisconsin. It became the state flower of California in 1903 and is now protected to prevent it picked or destroyed. Plant breeders worked with this pretty native and made it commercially available to gardeners everywhere in colours ranging from its native orange to purple. The California poppy's satiny, four-petaled flower opens in the morning and closes at night. It stays closed on cloudy or windy days as well.
California Poppy Care
California poppies require full sun. They do well in poor soil with good drainage. They are drought tolerant, but regular irrigation produces more blooms. It doesn't transplant well but grows quickly from seed and reseeds readily. The California poppy is perennial in areas within its native range, including southwestern Washington State, south to Baja California and east to western Texas. It thrives as an annual in colder climates.
