It's like a beacon amongst my hybrid teas! The color is outstanding! The pictures do NOT do it justice... it's even brighter than my white roses!

I bought this rose as an own root juvenile from a grower. For almost a year, it didn't bloom at all (probably because it was too young). I was growing dissapointed (I seriously thought I was doing something wrong) with it until about two months ago, I finally saw a single bud. It was WELL worth the wait! It hasn't stopped blooming since! It's still shrimpy... but since it is getting a bit older, once a spent bloom comes off, it's already working on another.

Electron has been growing in my parent's rose garden (which is now mine) for about 25 years. It's still one of the strongest rose plants in the bed and has one of the strongest fragrances. Like all hybrid tea roses in Northeast Ohio, it often dies down to the ground in cold winters, but it bounces back with beautiful blooms by mid-June. It does have large and quite numerous thorns, but I think that's its only downfall.
