a botanical sign we are about to get a torrential downpour.

another year of enjoying the taiyo tree peony bloom ( or at least i think it’s a taiyo peony ) for less than 24 hours before a torrential rainfall pummels the blooms. it happens every year. i realize they are blooming at a time of the year that’s prone to get torrential downpours but they are such good predictors of the timing of a downpour that it makes me wonder if the plant can sense a change in the barometric pressure which triggers a bloom?

the ant and the peony.

the ant and the peony.

anyone who has peony’s like our paeonia lactiflora variety known as "mons. jules elie" has no doubt noticed the buds are covered with ants just before they flower. apparently there’s an old wives’ tale that peonies need ants to bloom or be pollinated by them.

but those in the know say that while the ants are attracted to the sweet waxy coating on the bud, antless peonies bloom just fine.

the real question is how the peony’s know to bloom within 24 hours of a torrential rainstorm. i swear it happens every year and this year was no exception.
