Heliotrope
Growing a heliotrope plant brings satisfaction to the gardener not only in its dense cluster of delicate flowers, but in its delicious aroma. If that wasn't a good enough reason to grow these delightful blooms, they are also drought and heat tolerant and deer hate them. They are long bloomers that begin flowering in summer and offer up their fragrant bounty through the first frost. All parts of the plant are poisonous to humans and animals if ingested.
