flowers with white eyes. The seed may be sown in May, and 

 the young plants transferred to their permanent quarters in 

 September or October for flowering the following season. 



Verbascums are grand plants for shrubberies, or for growing in 

 back positions in large flower borders where they show off to 

 advantage. V. olympicum is one of the best, with large silvery 

 leaves and tall branched flower-spikes, 6ft.' in height; these are 

 covered with numerous rich yellow flowers, iin. across. Flowers 

 from May to August. V. phlomoides grows 5ft. high. It has 

 massive green . foliage and bright yellow flowers, which are pro- 

 duced successionally from May to August, as in the last-mentioned 

 species. 



Wallflowers {Cheiranthus Cheiri) are exceedingly showy and 

 effective sweet-scented border plants ; no garden, however small, 

 should be without a clump of these . old-fashioned and decidedly 

 popular plants. The seed should be sown in April and May — the 

 earlier the better — for flowering the following spring. There are 

 numerous varieties in cultivation, some with double and others 

 with single flowers. Harbinger, i^ft. high, has very large single 

 flowers, varying from brown to orange-red. Primrose Dame has 

 sulphur-yellow flowers. Golden Tom Thumb is very fine, pro- 

 ducing an abundance of rich orange-yellow flowers. It is also 

 a single and grows about ift. high. Ruby Gem is from 12m 1 . to 

 15m. high, with extra large single flowers of a ruby-violet colour. 

 The double-flowered German Wallflowers produce massive spikes 

 of large, sweet-scented flowers, which are remarkable for the 

 variety of their colours, and are highly appreciated for the 

 embellishment of flower-beds and borders.
