Container gardening is a great way to bring flowers, trees and shrubs onto a porch or patio. Using barrels as containers for flowers can provide enough soil to incorporate a moderately sized tree or shrub. Ideas for flowers in barrels include low, ground-cover creeping plants and tall, erect flowers such as tulips and lilies. Flowering shrubs and trees can also be included as flowering barrel plants.

Blooms are 1 inch wide and four or five petals appear in spring to summer. Plant a mock orange in full sun in cool summer weather or light shade in hotter summer-weather locations. Propagate via summer semi-ripe stem tip rooting.
The daylily (Hemerocallis hybrids) is a perennial with 10-40 inch strap-like leaves and stalked flowers. Flower colors and sizes vary, with each bloom lasting a day.

Divide every 3-5 years for best plant growth.
