I planted three kinds of Heliotrope this year, which can grow in compact form to ten inches tall or other varieties as tall as 2 to 3 feet tall, and is good in zones 9-11. I put two in pots and will bring them inside before weather gets too cold. The other two are planted in the ground so I hope they will winter over ok.
The above photos are of my True Beauty Heliotrope which I planted September 10, 2016 in a large container. I also planted two Atlanta Heliotrope and one Heliotropium Scentropia Blue. Heliotrope is often called Cherry Pie Flower due to its delicious scent. As you can see, the leaves are dark green and very attractive. The Heliotropes I mention here are Common Heliotrope or Heliotropium arborescens, not to be confused with Garden Heliotrope or Valariana officinalis (which I have not planted).
