Where NA 75038-J, Paeonia ostii, once grew, there are now apparently only hybrid seedlings from outcrossing with P. x suffruticosa elsewhere in the garden. The majority appear to be double-flowered with lavender-colored petals. To the extent that P. ostii is already in the background of P. x suffruticosa, these might also be considered to belong to that hybrid, but the proportion of P. ostii is significantly higher in them. | 2191277 | NA 88989 |

Seedlings are regularly produced in the original bed location. These are initially presumed to be pure P. ostii seedlings, but since there are some P. x suffruticosa growing in other parts of the museum, there is a chance that some might be hybrids. | 2165732 | NA 87564 |
