Yucca whipplei (Our Lord's Candle) seeds
Hardy Perennial (to -5C)
Flowers: Late spring to early summer
Height: Up to 1.5m
Position: Sun & well-drained soil.
Packet of 12 seeds
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) mixed in equal parts with vermiculite/perlite, and barely cover the seed with a very fine sprinkling of sieved compost. Propagate at 18-23C in a propagator, greenhouse or on a windowsill sealed in a polythene bag. 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. If temperatures are likely to drop below -5C, protect with fleece.
