I""I5 judiciously. 



Primulas for next Winter. — Fringed Primulas are 

 great favourites for flowering in heated greenhouses 

 and conservatories in winter, and now is the time to 

 sow seed. The seedsman sells them under the name of 

 Primula Sinensis, or Chinese Primrose, and he may offer 

 them in separate colours (even under distinctive names) 

 as well as in mixture. The pretty Primula Obconica 

 may also be sown now for blooming next winter. The 

 suggestions for sowing choice seeds in Chapter I. may 

 be applied to Primulas. 



Water Lilies. — Early May is a very good time for 

 planting aquatics, such as Nymphaeas, Water Haw 

 thorn (Aponogeton) and Water Violet (Hottonia). The 

 Nymphaeas (Water Lilies) are much the most important, 

 and those who have no pond may make a cemented 

 pool, or even grow the plants in tubs. The Sweet White 

 Water Lily (Odorata) is charming, and Chromatella, 

 yellow, is likewise a great favourite. For deep water 

 the common Nymphaea Alba had better be chosen, and 

 there is no difficulty in sinking it. The roots and soil 

 can be tied into bundles, weighted with heavy stones, 

 and thrown into the water. Where a pool is being made, 

 a few inches of good loam should be put on the bottom, 

 and the Water Lilies planted in it before the water is run 

 in. Thirty inches is a suitable depth for all the best 

 forms of hardy Water Lily. 



Coleuses. — These plants enjoy considerable favour for 

 conservatory decoration on account of the brilliant 

 colour of their leaves. If seed was sown a few weeks 

 ago, or cuttings inserted, in accordance with hints given, 

 there will now be a supply of young plants available 

 Give them separate pots now, good soil, and warmth, in
