Flowers that bloom over a long period of time can give your 3-season garden beauty throughout the year. There are a lot of flowers (perennial and annual) that have a short bloom time that leaves you wishing for more. Finding the right flowers for your 3-season garden that will provide you with the beauty of blooms all season long can be challenging.
I have been in your situation before and know that it is not easy to know which plants you should choose. I have taken the time to put together a list of 3-season plants with a description and information about the plant for your convenience.
You will find a list of options below that can help you to create your beautiful 3-season garden.
Hybrid Tea Rose
Hybrid Tea Roses (Rosa x Hybrid tea) are perennial flowers that bloom all season long. These roses display large blooms available in all colors of the spectrum (except blue or black) with sparse green foliage.
History of Hybrid Tea Rose
It is believed that the Hybrid tea rose ‘La France’ dates all the way back to 1867, although they did not become popular until the Peace Rose was officially branded in 1945. You can still find this cultivar today. And furthermore, they are considered one of the oldest classes of roses on the market to date.
Hybrid Tea Roses are a good addition to your 3-season garden when blended with other perennials.
Most commonly grown as a cut flower with quick-growing upright stems, very few leaves and generally just one bud per stem, they are better suited to being mixed in among other perennials.
Rapid growers, hybrid tea roses reach a height of 6 to 8 feet and can reach a width of 2-3 feet. Thriving in full sun, roses prefer loose, well-drained soil and will bloom all summer.
Once planted, water regularly, especially during hotter temperatures when plants can dry out faster.
It is beneficial to feed roses on a regular basis, providing them with enough fertilizer to satisfy repeat-blooming varieties.
These roses can be grown in zones 5 to 9.
Fringed Bleeding Heart
