The result of previous fortnight's sudden cold spell

..is an unusual number of floral abortions (what people usually call vegetative centers). A few of my bushes that were setting buds at the time have suffered from it and I had to pinch off quite a few buds. Most probably the short cold spell that followed an unusually warm February did that. It is just like the rose started setting the bud and then changed its mind about it. I suppose it may be hormone related.

How frustrating for you, Nik. The first blooms are always so exciting. It makes sense, though, that the sudden change in temperature would make the roses behave oddly. Must have been a shock to the system for them, just as it is for humans.

I get that on a lot of my roses. Sometimes I get bullheads. Ugly but fascinating.

Vegetative centers -- I usually call that 'proliferation'. I had not heard your term before. They can happen for all sorts of reasons. I once had a Souvenir de la Malmaison that proliferated all season long, each and every rose. I got rid of it.

Buford, I did not know that was called a bullhead. I see it once in a while. It fills me with regret, a wasted bloom.
