This is one of those quintessential yellow daffodil-looking daffodils. It has increased really well for me and should be an excellent choice for naturalizing. St. Keverne is said to be one of the best daff choices in the south, where less winter chill makes blooming of many daffs uncertain.

Description from Old House Gardens -
'Winner of the Wister Award, the ADS’s highest honor, this Cornish beauty blooms vigorously from Canada to the Gulf. As Bill Finch of The Mobile Press-Register says, it’s “perfectly sculpted,” and with its slender proportions it always seems to blend in beautifully. 2 Y-Y, 16-18”, zones 4b-9a.'
