SUMMER CLIMBING PLANTS.

and a fine succession of flowers are among 

 its other recommendations. It will climb 

 30 feet or more in a summer. 



VII. Double Rose Convolvulus, (Ca- 

 lystegia piibescens.) — A novel thing in its 

 way, just introduced from China ; for it is 

 a double flowering convolvulus — only the' 

 corolla is not arranged as you might sup- 

 pose, cup within cup, but with many irre-

gular petals, like a rose. Their colour is 

 a pale pink, very delicate and pretty ; and 

 they continue to bloom for some time in 

 July and August. This plant likes a deep, 

 rich soil, and not a very warm exposure. 

 Being a perennial from China, it is likely 

 to prove hardy in this climate. As yet, it 

 is rather rare, (though I see it advertised 

 by the dozen, in the April number, by Wat- 

 son, of Plymouth,) though it may doubtless

be had of Thorburn and others. [The 

 Calystegia is an acquisition, and we are 

 glad to find that a plant in our garden 

 has withstood the past winter. Ed.] 



VIII. The Crimson Passion Flower, 

 (Passiflora Kermesina.) — I close my list 

 of summer climbers with this — a green- 

 house plant, which perhaps surpasses 

 them all. It is certainly the most pro- 

 fuse flowering, graceful, and showy of 

 all passion-flowers ; and passion-flowers 

 are perhaps the most interesting of 

 climbers. I succeed in getting a fine 

 bloom of this passion-flower by shifting 

 a strong plant into a good sized pot with rich 

 compost, and plunging the pot up to the 

 rim in the open border, at the foot of a 

 trellis about the beginning of June. Here 

 it will take care of itself, and grow freely, 

 — reaching the height of some ten or 

 twelve feet by autumn ; and during the 

 months of August and September it gives 

 me a great quantity of flowers. The lat- 

 ter are not so large as some other pas- 

 sion-flowers, but are of a rich purplish
