Agapanthus

The agapanthus bud from 29 June is now opening, looking not unlike an allium, though those are all over now. It looks as if it'll be white. What we thought was one plant (and was certainly sold as that) has now had both blue and white flowers in past seasons, so presumably it's really two. Never both colours together though. This year's three flower heads all look to be white. Given that we bought it on the understanding that it was blue, it's mildly frustrating, but the flowers are too lovely for that to last long.
