Cut one stem and it fills a room. Petals twist outward from a soft coral center, bleeding into peach and then lavender at the tips. A slow color shift you only see up close. It was bred in South Africa by W.H. Maritz in 2000.

Growing Penhill Watermelon

Plant in full sun and pinch early to encourage branching. Remove side buds on each stem to push all the energy into one bloom. Cut when flowers are three-quarters open and firm to the touch on the back. Sear your stems in near-boiling water immediately after cutting, let them cool, then move to fresh water.

Spacing
Space roughly 2–3 ft apart
Staking
Stake early — stems carry heavy blooms and lean in wind
