Aquilegia

Common name; Columbine / Granny's Bonnet

Aspect

A hardy herbaceous perennial, bearing long spurred flowers in a wide range of colours in May and June.

 

Plants can grow up to 900mm (36") tall, with delicate foliage spreading to 300-500mm (12"-18") in diameter, and topped with flowers up to 75mm (3") long.

 

It is a prolific ‘self seeder’ and hybridizes quite easily hence the variation in flower colour, shape and size.

 

 

 

 

 

 

 

 

 

 

 

It is a useful plant for growing in containers and for ‘cut’ flowers.

 

Note; The seeds and roots are highly poisonous, and contain cardiogenic toxins which can cause severe gastroenteritis and or heart palpitations if ingested.

 

Cultivation;

 

Week 25 -27;

 

Cut flower stems down to ground level after flowering.

 

If required for propagation, collect seed prior to disposing of tops.

 

 

Sow ripe seeds in boxes / trays and lightly cover then place in a cold frame.

 

Alternatively; wait until Week 11 the following year, and germinate at 16°-20°C (61°-68°F)

 

 

Germination should take around 2-3 weeks.

 

Note; Seeds gathered from any particular variety may not come true to type.

 

Prick out the seedlings when large enough to handle (Week 28/16) into boxes or trays of potting compost, and grow on in a cold frame until planting out time.

 

 

Week 35; Plant out aquilegias 300mm. (12") apart in a sunny or partially shaded position in a moist, well-drained fertile soil.

 

 

Week 40; Increase stock by dividing established plants now, or wait until around week 15-18 the following year.
