Is this a member of the thistle family grown in dry, sandy soil or is it not blooming enough to tell?
Hi Mary,
no, this is a member of the ‘pink’ family, Caryophyllaceae. It is Silene latifolia, the white campion, which was previously called Lychnis alba. It is from Europe and has become established in many states.
Sincerely,
Dr. Steven Hill, Botanist, SCNPS
