PLEASE NOTE: Since plants are often sourced from the garden to order, sizes do vary a little, depending on how they come out of the ground, but I always endeavour to give a little more rather than less! They are sometimes shipped bare-rooted, but will approximate the size specified (e.g. a 9cm pot).

Trachelium caeruleum 'Pallas' AGM
Blue throatwort
Sold out
Type/Hardiness Herbaceous, Perennial, Tender
Flowering period Summer
Height 12-18in/30-45cm
Light preference Full sun
Soil preference Moist, well-drained
Sowing time/depth Spring, autumn, surface
Although a perennial, this stunning plant is usually grown as an annual, as it will not withstand frost. It forms a bushy mound of small leaves from which rise flower stems topped with large umbels composed of many tiny mauve flowers. A wonderful cut flower - much recommended!
Sowing and/or growing instructions
Mix the seeds with a little very fine sand and sow in spring or autumn, dusting the surface of a small pot of moist, but not waterlogged, compost with some of the contents of the packet. Keep under glass. A temperature of 20C may speed germination but heat is not required. Carefully transplant strongest seedlings into individual pots and plant out spring-sown plants when all danger of frost is past. Autumn-sown plants will need to be overwintered in a frost-free environment. Note: Seeds are like dust (I understand that there are around 100,000 per gram!) and usually sold pelleted, but I don't have the facilities to do this. I have managed to remove much of the chaff, but some is still present. I have examined the harvest under magnification and although it is impossible to quantify exactly how many seeds are in a packet there will be many hundreds, if not thousands.
