I bought a packet of Johnson’s seeds a while back. It’s was a bumble bee friendly mixture so I’m not sure what flower it is (picture above). They’ve grown but I’ve just noticed this morning a couple of stems have this white/grey blobs on it (picture below). Can anyone tell what this is? Is it safe to cut off or am I best just leaving it alone?
