Meconopsis betonicifolia - 50
Originating from the lush, mountainous regions of south-eastern Tibet, this almost magical blue flowered perennial is ideal for growing in a cool, sheltered position. For best results there is a little trick - provide it with an acidic, moist, yet free draining soil that won’t dry out – especially during the summer months. However during the winter the roots need to be kept more on the dry side, so if they are likely to be water logged - cover the plants to protect them from rain.
Pre-chill seed for 3 weeks. Sow in winter or early spring in good free draining seed compost covering the seed with a light sprinkling of compost. Place out of doors in a coldframe or sheltered spot. Keep compost moist, protect from heavy rain but not from frost which is beneficial. Leave for about five weeks then bring into warmth of 13-18C (55-65P).
At two-leaf stage transplant seedlings to 8cm (3in) pots. Keep shaded from strong sunlight. Gradually acclimatise to outdoor conditions and plant out when well established into deep, moist loam in sheltered semi-shaded position, spacing the plants 46-60cm (18-24in) each way.
