46 PERENNIALS. [March. 



pulchella and & pyramidalis require protection ; these are 

 easily cultivated, and flower in spikes from May to July. 



Spiraeas. A few species are showy plants, and continue 

 flowering from May to September. S. ulmaria multiplex, 

 Meadow-sweet, has sweet-scented white flowers, in long 

 dense spikes. S. JUipendula multiplex, Drop-wort, double 

 white. S. lobdta is a native, and has fine rose-coloured 

 flowers, and blooms in June and July ; S. japonica, beau- 

 tiful dwarf white ; these are the finest of the herbaceous 

 species, and will grow in any common garden soil. 



Stdtice, Thrift. A genus containing many fine herba- 

 ceous plants ; only a few of them are common in collec- 

 tions. The finest of them are scarce, and said to be "bad 

 to cultivate." S. vulgaris, once Armiria vulgaris, is a 

 valuable plant for an edging, and does well in our climate, 

 flowering in great profusion from May to July. When 

 done flowering, the stems should be cut off. The foliage 

 is an agreeable evergreen ; the plant increases rapidly, and 

 in a few years may be planted to a great extent. S. spe- 

 ciosa has red flowers, crowded in spreading panicles. S. 

 tartarica has also very showy flowers, and is now given to 

 the genus Taxanthema. S. latifolia and S. maritima 

 are the finest. T. latifolia and T. conspicua deserve at- 

 tention. They should be lifted every alternate year, and 

 sunk deeper into the soil, because they incline to grow out, 

 and are sometimes during summer killed by the drought. 

 Hence they are said to be " bad to cultivate." 



Trollius europaeus and T. osiaticus are fine border 

 plants, with large yellow semi-double flowers ; the petals 

 are much cupped, which causes the flowers to have a glo- 

 bular appearance. They are easily grown in any loamy 

 soil, and flower from May to July. Few flowers have the 

 curious globular character which these have. 



Veronica, Speed-well. This genus consists of about 

 one hundred and twenty species of herbaceous plants, be- 

 sides several varieties. The flowers are in long close 

 spikes, white, flesh-coloured, or blue ; they are generally 

 of the latter colour. Above sixty species are equally fine, 

 and being generally of the same character, the catalogue 

 at the end of this work will contain the best selection that 

 we can make. Very few of them are in the collections of 

 the country, although they are very showy, and flower
