Yucca filamentosa (Adam's Needle) seeds
Yucca are remarkable plants grown for the architectural value of their bold, sword-shaped leaves and showy panicles of flowers help on stout upright stems high above the foliage. Make excellent feature plants in containers or a bold statement in the border. Do particularly well in seaside gardens with poor, sandy soil.
Yucca filamentosa is evergreen, fully hardy and perhaps the most well known Yucca. From mid to late summer, bears tall panicles of pendulous, tulip-shaped, white flowers rising above green leaves that are edged with white threads.
Winner of the Award of Garden Merit.

Sowing Instructions: Sow at any time of year. Sow very thinly on the surface of a moist, free-draining, good seed compost (eg. John Innes) and just cover the seed with sieved compost. Seal in a polythene bag and propagate at 13-15C on a windowsill or greenhouse/coldframe (in summer). Germination should take place in 1-4 months and can be erratic, hence the need to sow thinly so that seedlings can be removed without disturbing the compost too much.
Growing Instructions: When the seedlings are large enough to handle, pot up individually into small pots (7-9cm) and grow on in well-ventilated, cooler conditions. Overwinter if necessary in a frost free place. When established, gradually acclimatise to outdoor conditions before planting out in late spring, 1.2-2m apart, in a sunny position and well-drained soil.
