No nglish cold seems to affect these plants : and yet their beauty is usually impaired when in 
flower, by the coldness of our nights. An obvious remedy for this is to protect their blossoms with 
glass screens : but the same result may be had if they are grown under north walls, so as to retard 
their flowering and to lower their excitability. It will also be found that the gradual thaw which 
takes place when the vernal sun has no access is a powerful safeguard against the consequences of 
being frozen ; while, on the contrary, the rapid elevation of temperature which occurs in a sunny 
border is invariably productive of bad consequences. 
The Chinese and Japanese are said to reckon their varieties of Moutans by hundreds, as we do 
our Roses. It is not improbable, now that the single and very slightly double kinds are beginning 
to establish themselves in Europe, that we too shall have the same dominion over them as over 
Camellias and Chrysanthems. The double varieties sometimes seed ; there is nothing whatever to 
prevent the single kinds from doing so ; and it is only necessary for the imported plants to become 
common to secure abundance of seed, out of which a new European race is sure to arise. The 
largest collection of these plants yet brought to Europe is that of Dr. V, Siebold, who imported 
them from Japan in 1844. They are said to have been obtained from the Imperial Gardens of Jedo 
and Mijako, and include all the finest sorts known in that empire. They are distinguished by the 
form and colour of the petals, and of the disk, styles, and stamens. None of them are completely 
double ; most are single ; some only semi-double ; and hence very likely to have seeds. The blossoms 
are described as being very large and in some cases very sweet-scented. 
The following list of these Japanese Tree Pseonies has been circulated by Dr. V. Siebold, who 
cultivates them all, as well as others, in his Nursery at Leyden.

The Wild Tree Patony. On this are worked the varieties obtained by cultivation. It deserves attention as well for the 
colour and sweet scent of its flowers as in a horticultural point of view, for its easy propagation by the division of its 
root and its hardiness, it having borne several winters in the open air without any shelter. Its colour is bright 
scarlet ; each petal has a black spot at its base, and the stamens are surmounted with golden yellow anthers.
