Would this be 50 degrees night temperature? And, would this apply to most

Day or night 50 degrees maximum temperature...., it just has to be consistent
for three or more weeks.
This will apply to Primary Pelargonium hybrids as well for example like P.
Splendide, P. Ardens, P. Laurenceanum, fulgidum types etc...P. crispums which
is the parent of the Angels types. P. domesticum, Also the uniques, and the
scented-leaf varieties P. graveolens x hybrids and P. x Odoratissimum from
the sub-genus P. Cortusina need this temperature in order to set bloom.
As far as the P. Zonale, P. Hortorum go and the Ivy leaved P. Peltatum and P.
peltatum x hortorum those Zonal, ivy crosses. I have found that they will set
bud no matter what temperature they are experiencing. Just be sure to dead
head spent umbels.
