That is absolutely beautiful! Dianthus is a favorite of mine but did not know they came as perennials!! I always get annual cottage pinks but will be sure to get perennials this time. That garden is going to grow more beautiful day by day!!! What does the marker stone say?? Can you see this memorial easily from your house? Where is it in relation to your house? I just think it is a lovely idea and wish I had one too! So much love and work you have put into it!!!
