A pleasant surprise popped up in my email this morning. Garden Gate eNotes sent me a gardening tip that brightened up a cold winter day. It’s about the Double “Knock Out” Rose, rosa ”RADtko”. Based on the photo and details, this appears to be a very impressive plant. Here are some facts that make it noteworthy: - It is cold hardy to Zone 5 and is reported to be always in bloom from late spring until frost. Flowers measure three and a half inches wide. Expect the plant to carry five flowers to a cluster and twenty five clusters per branch. This rose is mildly fragrant, drought tolerant and disease resistant. Because it is self cleaning, it is regarded as an easy care plant. It grows three feet tall and wide. Flowers are cherry red and its glossy green foliage turns to burgundy in autumn. The plant is usually available at most nurseries. For those who prefer to shop for online, Hortico offers excellent prices on roses and an extensive selection. ”Knock Out” is a registered trademark of its creator, William Radler.
