For a warm balcony, select Angraecum species that tolerate daytime temperatures of 25‑35 °C, can handle several hours of direct sun, and prefer intermediate‑warm humidity. Good options include A. eburneum, A. sesquipedale, A. arachnites, A. comorense, A. leonis and A. scottianum. These species originate from…
