The Best Flowers for Morning Sun
A site that receives the gentle morning sun is an ideal place to grow flowers which will not produce well if they are grown in partial shade, but that will wilt and struggle if exposed to the hot afternoon sun. For the greatest number of flowers, ensure that they are not shaded during the time the sun shines in their garden bed.
A native of the southern United States, the American snowbell (Styrax americanus) is a deciduous shrub that grows 8 to 10 feet high. It can also be trained as a single or multi-trunked small tree, but its best showing is as a shrub. The white, bell-faced flowers bloom in May. The American snowbell grows and blooms best if it is planted in a location with an eastern exposure; but ensure that it gets full sun during these morning hours. A lack of sun will reduce the amount of flowers it produces. Avoid planting it where it gets sun all day, especially the hot afternoon sun of a western exposure. American snowbell grows well as part of a border of native plants, massed in woodlands or along the edges of streams.
A showy flowering vine hardy through USDA Zone 4, clematis (Clematis spp.) is happiest in a location that is not too hot. The best place to grow them is in an area that is exposed to the morning sun and shaded from the hotter afternoon sun. They prefer cool, moist soil with good drainage, and that is slightly acidic. Mulch the base of the vine with peat moss, which will help acidify the soil and further benefit the plant. Most varieties bloom on the current year's wood and can be pruned back to ground level without sacrificing flower production. They can climb 10 feet or more and need a trellis or other support to climb upon.
Although climbing roses (Rosa spp.) require at least six hours of sun a day to produce blossoms, they prefer to get their sun during the morning and early afternoon. Avoid placing climbing roses where they are exposed to the heat of mid to late afternoon sun. If you have a site that is protected from harsh winds, your climbing roses will be even happier. Plant roses in rich but light, friable soil that is full of organic materials. Mulch the garden bed surrounding them to conserve moisture and reduce the growth of weeds. Provide a strong support structure for them to climb upon, such as a trellis, archway, arbor or sturdy fence.
Tie them to the support with strips of raffia or commercially available fastening strips. Ensure that they are far enough away from trees and shrubs that may compete for the roses' nutrients. Feed climbing roses with fertilizer specially formulated for roses two to three times during the growing season, following the application rates recommended by the manufacturer. Do not feed after mid August as the new growth will not have sufficient time to harden up before winter and will most likely succumb in the cold.
