A Coronary Garden was more popular in late Victorian times but as I discovered it goes back beyond the 17th century.
Coronary gardens were  used to grow flowers that could be used for wreaths and garlands and take their name Coronary from the word crown not the health problem.

The modern day equivalent is probably the florist shop or stall located at Crematoria

This photograph is not a true Coronary garden but a memorial garden in front of the cenotaph at Otley.

Tips for the Coronary Garden (1686)

• Do not separate off sets from Tulips until they are quite dry.
• Cotton Lavender makes a foot high hedge or border if kept well clipped.
• A layer of stable litter under the soil that is planted with Tulips, Anemonies and Ranunculus will help them thrive. They my survive without lifting.
• To grow Stock Gillyflowers chose a plant with excellent double flowers. Make it beare one branch of flowers and collect the seed. Sow in February in the hot bed and transplant in Michaelmas (September).

Note about Stock Gillyflower. – I originally took it to mean Carnation or Pinks of the Dianthus family but other plant dictionaries include stocks like Matthiola incana, or say stock gillyflower is the Cheiranthus; the queen’s gillyflower is the Hesperis or even any of several Old World plants cultivated for their brightly colored flowers.
