The seed compost should therefore have a high fibre (peat) content to ensure both good water retention and reasonable aeration. All seed should be sown thinly, and seedlings should be given as much light as possible. In some cases (e.g. Alstroemeria) a few seeds may germinate quickly but the rest will germinate a few at a time over a period of months. CLASS 1 The Anthemis, Lavatera, Clematis tangutica, Rhodochiton, Eccremocarpus, Alstroemeria, Pulsatilla and Fennel are very easy to raise from seed. Sow thinly and cover with 2-3mm layer of sifted compost CLASS 2 The Primula and Meconopsis species require slightly more care as the seeds are small and the young seedlings are delicate. A peaty compost (e.g. Equal parts of seed J.I. and peat) is best. The larger seeded species (P. Florindae, P. Japonica) may be very lightly covered, but the other species should be sown on the level surface of the compost. The surface must therefore be kept moist at all times. A rough peaty surface is important so that seedlings’ roots can easily penetrate the compost. CLASS 3 Rhododendron (including Azalea), Pieris, Gaultheria and other ericaceous seed is very small and should be sown on the surface of peat, or a mixture of about 10 parts peat to 1 part J.I. Compost. CLASS 4 The Astrantia, Angelica, Hosta, Gentiana, Sorbus, most Acer, and Clematis rehderiana seed requires a cold (and moist) treatment (stratification) before it will germinate. It may be sown in autumn (October/November) in pots and left outside until germination occurs in the spring. If pots are covered to protect them from mice, birds, etc., care must be taken that the soil does not dry out. Alternatively seed may be kept for about 90 days (3 months) in a domestic refrigerator (optimum temperature 1° - 5°C) on moist paper towelling in a covered dish. During this time the seed must not be allowed to dry out. After the cold treatment the seed is sown as Class 1. Some seed may germinate (even at 1°C) in the refrigerator within the 3 month period. The germinated seeds should be pricked out as soon as the elongated radical (little root) can be seen protruding from the seed, and the dish with remaining ungerminated seeds returned to the fridge immediately. With Astrantia and Sorbus, if the seed is kept permanently in the fridge and not sown after 3 months, a much higher percentage of germination can be achieved—though some seeds may not germinate until their third spring after 3 years in the fridge. Fungal growth may be ignored or the seeds may be cleaned and put on clean paper. CLASS 5 Paeonia, Lilium, Fraxinus (Ash) and most Acer griseum, A. palmatum, A. japonicum and A. nikoense seed require 2 cold periods (winters) before they will germinate (e.g. If sown in autumn/winter 2013 they will germinate in spring 2015). SOWING TIME Perennial species may be sown at any time so long as they can be kept growing for 3-4 months (remember to allow up to 6 weeks for germination) before becoming dormant. Sowing is best therefore done in spring, and autumn is best avoided (except, of course, for species requiring stratification) unless adequate light and heat can be provided to sustain growth over the winter GROWING ON Once the seedlings are crowded and large enough to handle (which depends on how thickly the seed was sown and how delicately you can manipulate the seedlings) they should be pricked out into individual pots in compost similar to the seed compost to grow to a reasonable size before planting out in the garden. Rhododendrons in pots should be grown in compost that is at least three-quarters peat. If sown in the spring Primula frondosa will flower later the same growing season. The other species of Primula, Meconopsis, Clematis, Anthemis, Fennel, Astrantia and Angelica will flower in the following season. Rhodochiton atrosanguineum and Maurandia spp. are usually treated as half-hardy annual climbers HOW TO ORDER YOUR SEEDS Please send the following 2 items to:The Seed Department Ness Botanic Gardens Ness, Neston Cheshire CH64 4AY Order Form Padded stamped self-addressed envelope Orders will be dealt with from January 2013.

Not all plants from seed come true. The meconopsis grandis shown right grown from seed at Ness has, instead of a single blue flower, double petals with some cream and purple markings. Meconopsis grandis Some seeds on the list have a collectors code that connects the plant back to where it originated in the wild. In the photo left the F stands for Gerorge Forrest followed by the code number which links to records that show where the plant was collected; in this example, Yunan Province, China.
