Gardeners' Notes:

I adore this plant and plan to include many more of them next year in my garden. The scent is amazing and it reminds me of my grandma's garden in the evening long ago. Easy to grow and VERY heat tolerant. We had a heat wave here in Portland this summer and this plant just bloomed and bloomed without missing a beat.

I've been growing this petunia with success for several years. This year I am growing it staked in the center of a pot with mounding Petunia integrifolia around the edges and it looks awesome! A lovely addition to a moon garden or an evening-fragrance garden.

From SELECT SEEDS catalog: "This heavenly scented white petunia has a modern name, but harks back to 1823 when an explorer plucked it from the mouth of the Rio de la Plata in South America. It does survive rainstorms with no marking and dissolving as some petunias are prone to do, and its sweet scent makes it an essential part of the evening garden. Self-sows."
