TENDER PLANTS FOR A WARM CORNER.

must be as well ripened as possible, and must not be frozen in winter. 

 At Bagatelle, by way of great precaution, artesian-well water is run 

 in during severe weather in winter, but it is held that the rhizomes 

 are safe if they are not frozen. N. luteum is said to be still hardier. 



Fbuits. 



Citrus medica. — In Devon and Cornwall I have known Citrons 

 splendidly grown on south walls quite without heat, and only with a 

 covering of glass lights in winter, I draw attention to this because 

 other fruits can no doubt be grown equally well in the same way. 

 Near Falmouth, I am informed, the Citron grows and fruits on a wall 

 without any further protection. With top glass protection in winter 

 both Citrons and Lemons are grown successfully near Ilfracombe. 

 Near Plymouth, on a wall, the Citron fruits splendidly, and the only 

 protection' it ever gets is Frigi-domo canvas. Close to it an Orange 

 grows quite in the open, but it has been injured, though probably 

 the damage was done more by salt winds than by frost. 



Asimina triloba, North American Papaw. — Good varieties of this 

 have been found wild, and some have been obtained by selection. 

 Professor Foex considers this an important fruit. It is quite hardy 

 at Cambridge, and flowers freely, but does not fruit. It ranges south 

 to Mexico, and may at some time require more heat. In Mexico it is 

 known as * Ahonillo. ' 



Citr7is Aurantium, Orange, Tropical Asia. — At Coombe Eoyal, near 

 Kingsbridge, Devon. I have seen oranges flourishing on walls like 

 peaches. They should succeed where the Citron succeeds. In the 

 JouENAL E.H.S., xxxviii. (1912), p. xxxiii., attention is drawn, with a 

 figure, to the * Satsuma ' or * Ooushin ' Orange, one of the hardiest. 

 The hybrid with Citrus trifoliata grows in the open at Bitton. 



Cydonia sinensis, Chinese Quince. — Has been mentioned as grow- 

 ing at Cambridge, but as a fruit requiring a warm corner may be 

 mentioned again. 



Feijoa Sellowiana {Bot. Mag,, t. 7620), South Brazil and Uruguay, 

 — " The coming fruit for all parts of California; " it is allied to Guava, 

 and not unlike in habit and foliage. The flowers are red and white 

 and very ornamental. The fruit is green, two inches long, and 

 fragrant. It grows well on a wall at Kew. I am informed that from 

 its poor success in the south of Europe it is not likely to succeed as a 

 warm-corner fruit in this country. With Canon Ellacombb at Bitton 

 it has succeeded during the last three years as a shrub some distance 

 from a wall. 



Diospyrus Kaki, Persimmon or Japanese Plum. — This grows per- 

 fectly on a wall near Newmarket, but does not flower. It can bear 

 much more cold than a Citron, and ought to succeed well where the 

 latter succeeds. In the United States the Lamopan Persimmon is 

 expected to succeed under conditions that are not good enough for 

 other kinds. It appears to be a good kind, succeeding as far north 

 ^is Pekin (see Year-booh, U.S.A. Dep. Agr., 1910). Persimmon
