Keep in mind when planting that White katie is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside. White katie requires a soil ph of 6.1 - 9.0 meaning it does best in weakly acidic soil - weakly alkaline soil.
Ensure that temperatures are mild and all chance of frost has passed before planting out, as White katie is a tender plant.
The botanical epithet is from the Latin brittoniana meaning “to have existed in imperial times” or “named by Britton”.
