Coreopsis is a garden classic. Within the genus are many sizes of plants, colours of bloom and shape of blooms. Jethro Tull can grow up to 18"/45cm which makes it a great filler plant for the border. The tubular shaped petals, though, are the real treat with this coreopsis.
Please note: This picture shows what the plant may look like when more mature. At this time our plants may not look like this.
