Rose of Sharon shrubs (Hibiscus syriacus - L.) bloom profusely from mid to late summer. Flowers of maroon, white, lavender or blue attract hummingbirds and butterflies like magnets. Rose of Sharon is easy to grow from seed for anyone who is patient and curious about plant propagation. Once established, this ornamental shrub grows two to three feet per year, self-seeds and needs very little maintenance.
Things You'll Need
- Rose of Sharon seed pods
- Small saucer or cup
- Potting soil
- Medium flowerpots
- A sunny, warm windowsill
Gather Rose of Sharon seed pods in the fall. If the shrub you've got your eye on belongs to a neighbor, ask permission first. Pluck the pods when they turn brown and brittle, before they break open and scatter the seeds.
Fill your medium-sized flowerpots with moist, rich potting soil. Tamp it in firmly, but don't pack it down too hard.
Hold the Rose of Sharon seed pods over a small saucer, and gently break them open. Just a few pods will yield more than enough seed for this project.
Plant several seeds in each flowerpot, about one inch deep, to increase your chances of getting at least one healthy plant per pot. Water thoroughly.
Set the pots in a warm, sunny spot in your home. Windowsills are excellent places, particularly if the window faces south. Keep the soil moist but not soggy. In a few weeks, the seeds will germinate. Thin, or transplant seedlings to new pots, if you get several healthy sprouts.
Maintain your Rose of Sharon seedlings in their pots for the first year; then transplant them outdoors in a protected, sunny area. Once established, they will grow like weeds and need very little care other than occasional pruning.
