670 PB ACTIO AL GUIDE TO GARDEN PLANTS heliotropium 



height of 6-10 ft., and have enormous 

 leaves. 



Wigandias for the outdoor garden are 

 raised from seeds sown early in March 

 or February in heat. They germinate 

 readily, and when the seedlings are large 

 enough they are priclied off singly into 

 pots in light loamy soil, and gradually 

 given as much Ught and air as possible, 

 and also a cooler atmosphere, so as to 

 thoroughly harden them off by June, 

 when they may be transferred to the open 

 ground. In the autumn plants may be 

 raised from cuttings inserted in sandy 

 soil, and placed in bottom heat. When 

 well rooted they may be potted and 

 wintered in a warm greenhouse until the 

 following June. Such plants are larger 

 and stronger than those raised from seed 

 and give an effect in the garden much 

 sooner. Boot cuttings may also be made 

 in brisk bottom heat. The following 

 kinds may all receive the same treatment. 



W. macrophylla {W. caracasana). — 

 A fine foliage plant about 10 ft. high, 



native of Caracas and the mountains of 

 New Grenada. Leaves large, elliptic 

 heart-shaped, acutish, hairy-tomentose, 

 and ruddy brown above. Flowers in 

 April (in greenhouses), lilac, on one-sided 

 crosier-like spikes. 



Culture Ac. as above. 



W. urens. — A Mexican species about 

 6 ft. high, looser in habit than W. macro- 

 phylla and not quite such a fine-looking 

 plant. The stems are covered with short 

 stinging hairs, and the large heart-shaped 

 sinuate-lobed and toothed leaves have 

 reddish stalks. Flowers in autumn, 

 violet-blue, in crosier-like panicles. 



Culture dc. as above. 



W. Vig^eri. — A vigorous quick-grow- 

 ing species with stems G-8 ft. high and 

 2-3 in. diameter ; native of Mexico. 

 Leaves oval-eUiptic cordate at the base, 

 irregularly and sparingly toothed, about 

 3 ft. long, with a stalk 9-12 in. long, and 

 over 20 in. across. Flowers in autumn, 

 lilac-blue. 



Culture d-c. as above. 



LXXVIII. BORAGINEiE— Forget-Me-Not Order 



An order consisting of annual or perennial herbs, shrubs or trees, rarely 

 climbers, roughly pubescent or hairy, with round stems and no stipules, leaves 

 alternate or very rarely opposite or vvhorled, entire, toothed, or very rarely 

 lobed. Flowers in one-sided crosier-like racemes or panicles, sometimes 

 solitary and axillary, regular or rarely oblique, hermaphrodite or very rarely 

 polygamous by abortion. Calyx inferior with a bell-shaped, rarely cylin- 

 drical tube, or often very short or absent, usually with 5 teeth or lobes, very 

 rarely fewer, or 6-8. Corolla gamopetalous funnel-shaped, tubular, salver- or 

 bell-shaped or somewhat rotate, with 5, rarely 4, or 6-8 lobes. Stamens equal 

 in number to the corolla lobes and alternate with them. Ovary superior, 

 normally consisting of 2 carpels, sometimes entire, or laterally somewhat 

 4-lobed. Style simple, with a simple or 2-cleft stigma. Fruit consisting of 

 2-4 distinct nuts. 



The order consists of nearly 70 genera and about 1200 species distributed 

 over all parts of the world, especially in the north temperate regions. 



HELIOTROPIUM (Cherry Pie; 

 Heliotrope ; Turnsole). — A genus con- 

 taining 100 to 150 species of pretty, more 

 or less hairy herbs or bushes, with alter- 

 nate, very rarely almost opposite, leaves. 

 Flowers often small, in one-sided crosier- 

 like or curled spikes. Calyx 5-lobed or 

 parted. Corolla funnel- or salver-shaped, 

 6-lobed ; stamens 5 ; ovary undivided, but 

 often 4-lobed and 4-celled. 



Culture and Propagation. — The Com- 

 mon Heliotrope or Cherry Pie (H. peru- 

 vianuiri) is a great favourite in gardens, 

 more so formerly perhaps than at present, 

 on account of its delightful fragrance and 

 masses of bloom, which, however, are 

 what may be called ' qviiet ' in ooloiir. 

 When grown out of doors from May to 

 October they should be planted in light 

 and rather dry soil, and are very effective
