Gardeners' Notes:

Indeed, the flowers are small, but that makes it charming. And they do last quite a while-- unless the deer find them.

Mine do not get the optimum amount/hours of sun, but I did the best I could in finding a place for it. It continues to put out new growth. I used Miracle Gro outdoor soil mixed with our red clay soil and I water it when the surface gets bone dry. I also used a systemic insect control, but it needs a booster, as I'm seeing thrips hanging around....

Positive coriaceous On Jul 9, 2014, coriaceous from ROSLINDALE, MA wrote:

Very deep warm red, dark but luminous. It really does glow like incandescent lava. Unlike most reds, it does not shift towards blue as the flowers age.

Flowers are 2.5", with around 25 petals, produced in large clusters.

The flowers last a long time (over a week). The petals are shed cleanly before they brown.

I see this sold here in the US under the name of 'Lava Flow' in addition to the more accurate 'Lava Glow'.

Sprays are popular for exhibition at rose shows.

Relatively disease resistant, but it still needs regular fungicide sprays to keep it from defoliating here due to black spot.

I let my husband pick out a rose that he wanted and this is what he picked. I wasn't thrilled about it because I typically like bigger blooms but I have to admit this is a great rose. I've had it about a month and a half and it's already on its second flush. The blooms really last a long time as in a week or more and they don't fade with the heat. The color is beautiful and it definitely has earned its place in my flower bed.

This is a wonderful little rose, even for beginning rose growers like myself. Covered in roses when in bloom, and blooms for long periods. Not my favorite rose (have a soft spot for tea roses) but certainly one I recommend.

Adore the dark red color on this floribunda.

This rose has the most extrordinary, beautiful color. Absolutely the darkest red but without actual blackish overtones. The plant does quite well here despite our heat, wind and cold.

My favorite rose. Actually it is a dark red, and sometimes appears very dark in the proper lighting. ARS rating 8.7. Very high.
