Frequently Asked Questions

How is Regal Pelargonium different from Zonal Geranium?

It has larger, velvety blooms with dramatic petal markings and ruffled edges, and blooms mainly in spring and early summer rather than continuously, needing cooler night temperatures for best flowering.

Why won't my Regal Pelargonium flower indoors?

It needs cool conditions, particularly nighttime temperatures of 50–55°F, to trigger its best flowering — warm indoor nights can suppress bloom production.
