A hybrid raised in the nursery of Messrs Simon-Louis Frères, at Plantières, near Metz, its parents no doubt A. hippocastanum and A. × carnea. The seed came from the former, so that it is (if the generally accepted parentage of A. × carnea be correct) three-fourths common horse-chestnut and one part the red buckeye (A. pavia). It shows the characters of both its parents in the leaf; the leaflets being stalkless, as in A. hippocastanum, yet showing the more strongly ridged and uneven surface of A. × carnea. In shape and size the panicle is like that of A. hippocastanum, but the whole flower is suffused with a charming shade of soft pink, which it inherits from the other parent. In habit and general appearance it is intermediate. It has flowered at Kew for many years past, and I consider it a very beautiful and desirable acquisition. It has developed no fruit at Kew, and I understand from Mr Jouin, of Plantières, that it does not bear seed in his nursery. For public places this is an advantage. It is still true (1966) that it has produced no fruit at Kew; the fact that it is a triploid explains this sterility.
This is properly placed under A. × carnea as cv. ‘Plantierensis’.
