A sunny spot
She’s a sun-lover, so give her the brightest spot available. She’ll be ok in a dappled spot, but not full shade.
Moist soil
Give her a good drink about once per week – more in very hot weather. She likes her soil to stay moist.
Shelter
She’s not a fan of strong wind, so try to put her somewhere that’s sheltered from stiff breezes.
